06-12 Over-Torque limit
a
Factory setting 150
Settings 0~250%
This parameter sets the over torque limit used during torque control, V/F control, and
Vector control. When using an analog input set for “Torque Limit”, this parameter will set
the actual limit. The value in this parameter is based on the AC drive output current in %.

Electronic thermal relay function disabled
This parameter selects the type electronic thermal relay function based on the motor
characteristics.
Inverter/vector motor = windings designed for AC drive output and low speeds with
high currents.
Standard motor = windings not designed for AC drives. Motor has a shaft mounted fan
which offers poor cooling at low speeds
