Note
• Basic parameters for inverter operation must be correctly set before you can operate the
inverter in torque control mode.
• Torque control is not available during low speed regeneration and light load operation. Operate
the inverter in vector control mode instead.
• Do not switch between Fx and Rx operations while the inverter is operating in torque control
mode. An overcurrent or reverse deceleration fault trip may occur as a result.
Torque Control – Details
Code Description
DRV-08 Trq Ref
Src
Select the input source for the torque reference.
Setting Description
0 Keypad-1 Sets the torque reference using the keypad (up to 180%
of rated motor torque, set at CON-02). 1 Keypad-2
2 V1 Sets the torque reference using the analog terminals.
The torque reference changes based on the set value at
IN-02 (Torque at 100%).
For example, if IN-02 is set to 200%, the torque reference
becomes 200% when 20 mA current is supplied.
The setting can be viewed in monitor mode. Set CFG-06
–
08 to “ 19 (Torque Ref) ” .
3 I1
6 Int485
Sets the torque reference using the built-in RS485
communication device.
CON-02 CMD
Torque
Sets the torque reference for keypad input.
IN-02 Torque at
100%
Sets the torque reference for analog terminal input.
CON-35 SL2 L-
ExcitLmt
This is the ratio to improve the operating characteristics in the low torque/low
speed range by lowering the magnetic flux current. However, if the value is set
too low, stable sensorless control may not be possible.
CON-62 Speed
Lmt Src
Select the input source for the speed limit.
Setting Description
0 Keypad-1 Sets the speed limit using the keypad (CON-63 FWD
Speed Lmt / CON-64 REV Speed Lmt). 1 Keypad-2
2 V1 Set the torque reference using the analog terminals, in
the same manner as setting a frequency reference.
The setting can be viewed in monitor mode. Set CNF-21
