If voltage of 1 OV is applied

terminals 3 and 4, the torque

the same as the torque which the motor is able to

provide with the set Imax current.

Adjustment of the torque controller

The torque controller must be set when the drive is

When

For this, torque

must be established.

at terminals 3 and 4.
