7-3 Description of Functions
● When setting with a positive value, it will be a torque command of forward
power running or reverse regeneration.
● When setting with a negative value, it will be a torque command of forward regeneration or reverse power running.
● The setting range of torque command is different when selected by mode A (F1320=1) and mode B (F1320=2).
(Refer to the above table)
Note: If the torque command is too small because of the load, it may cannot accelerate or decelerate.
Please pay attention to this.

Note 1: If the upper value of the torque limiter is too large, the motor may accelerate rapidly, special attention must be
paid when setting this upper value.
Note 2: When the lower value of the torque limiter is smaller than the torque at the load side, the inverter may be unable
to accelerate.
