Proper use and handling of the product will ensure proper product performance, will length product life, and may prevent possible accidents. Please read this manual thoroughly and handle and operate the product with care. The word “Unit” is also capitalized when it refers to an OMRON product, regardless of whether or not it appears in the proper name of the product. The abbreviation “Ch,” which appears in some displays and on some OMRON products, often means “word”. Consult your OMRON representative when using the product after a long period of storage. WARNING Do not touch the inside of the Inverter. Doing so may result in electrical shock. Doing so may result in injury. Caution Do not pull on the cables. Doing so may result in damage to the product or malfunc- tion. Not doing so may result in fire. Caution Confirm that the rated input voltage of the Inverter is the same as the AC power sup- ply voltage. An incorrect power supply may result in fire, injury, or malfunction. Caution Connect the Braking Resistor and Braking Resistor Unit as specified in the manual. Doing so while the RUN signal is turned ON may result in injury. Caution Be sure to confirm permissible ranges of motors and machines before operation because the Inverter speed can be easily changed from low to high.

2-1-2 Installation Conditions H Cautions and Warnings WARNING Provide an appropriate stopping device on the machine side to secure safety. (A holding brake is not a stopping device for securing safety.) Not doing so may result in injury. When installing the Inverter, always provide the following installation space to allow normal heat dis- sipation from the Inverter. 120 mm min. Upon completion of installation, always remove the cover from the Inverter. Otherwise, ventilation will be affected, causing the Inverter to overheat. Not doing so may result in electrical shock. WARNING Wiring must be performed by authorized personnel. Not doing so may result in electrical shock or fire. Remove the Digital Operator from the front cover before removing the front cover. For models of 15 kW or less (both 200-V and 400-V class), do not remove or mount the front cover without first removing the Digital Operator;. Do not mount the front cover with the Digital Operator attached to the front cover, otherwise Digital Operator may malfunction due to imperfect contact. There- fore, always follow the instructions given below when connecting the Inverter to periph- eral devices and other parts. H Wire Size and Round Solderless Terminal For the main circuit and ground, always use 600-V polyvinyl chloride (PVC) cables. Install one wiring circuit breaker per Inverter. When a magnetic contactor is installed on the primary side of the main circuit to stop a load forcibly, however, the regenerative braking does not work and the load coasts to a stop. It is recommended that a Noise Filter be installed at the Power Supply to minimize this noise transmission. This is extremely hazardous. Also, be careful not to short the output wires. Alternatively, cables can be routed through a grounded metal pipe to prevent induction noise. Refer to the following for the definition of harmonics (i.e., harmonic currents with voltages) and countermeasures against the generation of harmonics from the Inverter.http://www.drupalitalia.org/node/66080
Harmonics (Harmonic Currents with Voltages) Definition Harmonics consist of electric power produced from AC power and alternating at frequencies that are. The output current of the Inverter is comparatively high. Therefore, the ratio of harmonics in the output current of the Inverter is higher than that of any other electric machine. With DC and AC Reactors DC reactor (optional) When using a Braking Resistor Unit, set L8-01 to “1” (i.e., overheating protection of the braking resis- tor) and set L3-04 to “0” (i.e., no decelerating stall prevention) or “2” (i.e., braking with stall prevention). Braking resistor Inverter Caution. There are four types of PG speed control, as shown below. Select the type that fits the application and control method. FWD: Lit when there is a forward command input. REV: Lit when there is a reverse command input.S Inverter Modes The SYSDRIVE 3G3FV Inverter’s parameters and monitoring functions have been organized in groups, so it is easier to make settings and read data. These function groups are known as modes. The access level restricts which parameters can be set or displayed. Level. S Setting Parameters in Each Access Level The displays in program mode differ for each access level. (There is no difference in other modes.) This section provides the procedure to change the acceleration time to 20 s in each access level. The acceleration time (C1-01) is a parameter in program mode.

Setting “7”. To clear the emergency stop, turn the run command OFF, turn the fast-stop input OFF (or ON for an N.C. Auto-tuning is the only setting for basic operation with open-loop vector control. When the voltage limit restricted by the input power supply is reached near the rated motor speed, vector control cannot be established and speed accuracy will be reduced. If a load is connected when auto-tuning is performed, not only will incorrect motor parameters be re- corded, but the motor may operate erratically resulting in dangerous conditions such as loads falling from vertical axis motors. The motor parameters will revert to their default settings if a fault occurs. Set these parameters again when auto-tuning. Fault display Probable cause and remedy Data Invalid There was a fault in the data set during auto-tuning. Parameter F1-09 sets the length of time that the motor speed must exceed the overspeed detection level in order to generate an overspeed fault. Parameter Display name Setting.
Parameter F1-11 sets the length of time that the difference between the motor speed and reference speed must exceed the PG speed deviation detection level in order to generate a PG speed deviation fault (DEV). H Motor Selection Setting (E1-02) Set the motor selection (E1-02) to the type of motor to be used. This setting is used as a basis for motor protection Valid access levels Parameter. The motor will operate during auto-tuning, so be sure that it is safe for the motor to operate before press- ing the Run Key. Initialize the torque limit parameters (H7-01 to H7-04). The acceleration time is too short. Increase acceleration time 1 (C1-01). Secondary current reference Frequency reference U1-21 U1-22 Detected speed Note In vector flux control, the ASR’s P gain is the maximum frequency standard. H Regular Gain Settings (C5-01 and C5-02) Parameter C5-01 sets the proportional gain of the speed loop (ASR), and C5-02 sets the integral time. Motor speed (Hz) Note If C5-07 is set to 0.0, ASR P Gain 1 and ASR I Time 1 are used for the proportional gain and inte- gral time at all frequencies. Lengthening the integral time lowers the re- sponsiveness, and weakens the resistance to external influences. Vibration will occur if this setting is too short. This parameter cannot be changed during operation.Set this time as short as possible in any application where safety cannot be ensured.ASR Integral Reset (Setting E) When one of the multi-function inputs is set to “E,”. Multi-function analog output 2 (terminal 23): Outputs the actual motor speed (0 to 10 V). Output torque Forward direction Forward torque limit Regenerative torque limit Reverse Forward Regenerative torque limit Reverse torque limit Reverse direction Note 1. When the forward torque limit has been set, the analog input signal acts as the limit value for torque generated in the forward direction. The default setting does not normally need to be changed.
Set the parameter if stable slip compensation is required in the constant output area where the operating frequency is as high as or higher than the rated frequency. This function is effective for equipment in which a starting torque is required, such as machinery with a high friction load or cranes. Use either the DC injection braking at startup (b2-03) or the “DC braking reference” multi-function input (set value: 60) to raise the motor’s magnetic flux in advance before startup. (The magnetic flux from the DC injection braking at startup (b2-03) can also be brought up quickly. The default settings shown in the table are for 200-V class, 0.4 to 1.5 kW Inverters. Note 4. The default setting de- pends upon the type of Inverter. (The table shows the default setting for 200-V class, 0.4-kW In- verters.) Calculate the rated slip (E2-02) from the value shown on the motor’s nameplate with the following equa- tion and set this value. Motor core-saturation coefficient 2: Core-saturation coefficient when magnetic flux is 75. Normally these values aren’t shown on the motor’s nameplate, so it might be necessary to contact the motor manufacturer. Increase this setting if vibration or hunting occur.Factor of 4: By counting the rising and falling edges of phase A and phase B, this method has four times the resolution of the PG. The torque reference value cannot be set with the Digital Operator. Valid access levels Parameter Display name Setting Units Default. With torque control, the motor sometimes rotates at high speed with no load or a light load. When frequency reference (current) terminal 14 has been set to frequency reference by setting parameter H3-09 to 1F, this terminal is also used as an input terminal for the speed limit. In this case, the actual speed limit value is the sum of the voltage input value at terminal 13 and the current input value at terminal 14. Advanced Note This parameter cannot be changed during operation.
Set the speed limit bias as a percentage of the maximum frequency. This parameter cannot be changed during operation.

Setting Name Forward Torque Limit Reverse Torque Limit Regenerative Torque Limit Torque reference (The input limits torque in both the forward and reverse directions during speed control.) Speed Limit (Limits torque in both the forward and reverse directions.) Set the analog input terminal’s signal level, gain, and bias to match the actual input signal. H Setting Motor Parameters The motor parameters (function E2) will all be set automatically when auto-tuning is performed, so it normally isn’t necessary to set them manually. Adjust this setting when a torque limit or torque control is being used and the output torque varies with the ambient temperature. The default setting does not normally need to be changed. The functions that can be used in common are marked with a “S ”. DC injection braking current is set as a percentage of Inverter rated output current, with the Inverter rated output current taken as 100. The PID control provided by the SYSDRIVE 3G3FV Inverter is not suited for control that requires a responsiveness of 50 ms or less. Application Control contents Sensors used (example) Speed control Speeds are matched to target values as speed Tacho-generator information in a mechanical system. Speed information for another mechanical system is input as target values, and synchronized control is executed by feeding back actual speeds.
Re- sponse is possible with respect to changes both in target values and the control object. Control object Target value Feedback value Basic PID Control This is the basic form of PID control. Set value Contents PID disabled. Adjust the responsiveness of the PID control by means of the proportional gain (P), integral time (I), and derivative time (D). Explanation of Set Values Parameter b5-07 adjusts the PID control offset. Set the characteristic according to the relationship between the Inverter’s output frequency and the feedback value. Positive characteristic: The feedback value increases when the Inverter’s output frequency in- creases. Feedback loss detection enabled. (The Inverter will continue operating with a warning output turned ON.) Feedback loss detection enabled. (The Inverter’s protective function shuts off the output.) Set this parameter to disable or enable the feedback loss detection function and to specify the opera- tion of the Inverter after the loss of the feedback signal is detected. The vibration will be reduced as the integral time (I) is lengthened. Response Before adjustment After adjustment. With the SYSDRIVE 3G3FV, S-curve characteristic times can be set respectively for beginning accel- eration, ending acceleration, beginning deceleration, and ending deceleration. If speeds are unstable, raise the set value. Valid access levels Parameter Display name. Make ad- justments in the following cases: If the wiring distance between the Inverter and the motor is long, raise the set value. If the motor capacity is less than the Inverter capacity (the maximum application motor capacity), raise the set value. When the frequency reference is zero and a run command is input, the motor operates at the frequency reference lower limit (d2-02).

Be sure to install the Cards in their correct locations. Wait at least one minute (or at least three minutes for models of 30 kW or more), and then remove the Inverter’s front cover. Check to be sure that the CHARGE light is turned OFF. Explanation of Settings Setting Description. The second digit below the decimal point is set by bits 8x10, 4x10, and 2x10, so the settings are made in units of 0.02 Hz. For example, if “0” (1F) is set, when the output frequency is 60 Hz there will be an output of 60 pulses per minute. (Duty 50) H Setting a Wired SYSMAC BUS Interface Card (F8) When using a 3G3IV-PSIG Wired SYSMAC BUS Interface Card, set the following parameter in order to specify the operation of the Inverter for communications failures. Coast to a stop. Fault Emergency stop time: Decelerates to a Fault stop according to the C1-09 setting. Continuous operation. (See note.) Alarm Note If the parameter is set to 3, the Inverter will operates without references from the host controller. This stored frequency will be retained even after a power interruption and the motor will be restarted at this frequency when a run command is input again.Turning the input OFF has the same effect as setting H3-05 (the multi-function analog input selector for terminal 16) to1F.
When a fault has occurred, be sure to find out what kind of fault occurred, take steps to correct the cause of the fault, and restart the Inverter. It is possible to damage the Inverter by repeatedly resetting a fault without correcting the cause. There are 16 external fault inputs available with all 16 combinations of the following variables. Select the setting with the desired combination. External Fault Input level Detection method. Deceleration time set in b3-03. Maximum frequency or set frequency Frequency reference that was set Output frequency Minimum baseblock time Speed Torque Control Change (Setting: 71) Speed control Torque control With this setting, the multi-function input can be used to switch between speed and torque control. These parameters can- not be changed during operation.The run command is ON and voltage is being output. Inverter Operating 2 (“During RUN 2,” Setting: 37) The Inverter is not outputting a frequency. The position has been brought within the zero servo completion width (b9-02) after the zero servo command was input. This output function indicates that zero-servo position control has been completed. The Inverter’s status monitor item U1 can be output as multi-function analog output. Refer to the table of status monitor items in page 3-12 for details. 6-5-8 Protective Functions: L H Motor Protection Settings (L1) Valid access levels.

Set this parameter when a high-speed motor is being used in the high-speed range (the high frequen- cy range above the base frequency). Therefore the actual deceleration time becomes longer than the deceleration time that has been set. This can be adjusted, however, by set- ting a shorter deceleration time than for the 0 setting, so that the actual deceleration time will also be shorter.

Press the Menu Key to display the operation mode, and enter the drive mode by pressing the Enter Key. The frequency reference is too low. The load may be too big. The 3G3FV has a stall prevention function and an automatic torque boost function, but the motor responsiveness limit may be exceeded if acceleration is too rapid or if the load is too big. When “1F” (frequency reference) is set for parameter H3-09 (multi-function analog input terminal 14), a frequency corresponding to the terminal 14 input input voltage (current) is added to the frequency reference. The Inverter goes into DC braking status for 0.5 seconds after deceleration is completed. (This is the factory-set default.) To make sure that the brake holds, use the frequency detection function and apply the brake only when the detected frequency drops to 3 to 5 Hz or lower. If the motor continues operating at low speed, without com- pletely stopping, and after a deceleration stop has been executed, it means that the DC braking is not decelerating enough. If this occurs, insert a diode as indicated by section A below. Section A 24 V 1 to 8 3.3 K 8-21.
