Multi-function Compact Inverter 3G3MX2-V1 User’s Manual (I585-E1)
Precautions for Correct Use
When the torque limit function is used in a low speed range, the inverter may fail to start the
motor and detect an overload. In this case, use this function in conjunction with the overload
limit selection (b021/b221/b024).
Use this function to stop temporarily the frequency acceleration/deceleration function (LAD) when the
torque limit function is activated. This function, as well as the torque limit function, is enabled when the
1st/2nd Control Method (A044/A244) is set to 03 (Sensorless vector control).
• LAD functions to calculate the transient frequency reference value to enable the motor to reach the
reference frequency in the set acceleration/deceleration time.
• This function stops the frequency reference temporarily at the transient value calculated by LAD
when the torque limit function is activated and restarts at that frequency when the torque limit is reset.
• To stabilize the motor operation after resetting the torque limit, enable this function.

Transient frequency calculated by LAD changes even when torque
limit function is activated (b045 = 00).
Transient frequency calculated by LAD stops changing temporarily
when torque limit function is activated (b045 = 01).
