10.5 Adjustment of the Imax limit
The torque controller has the same as the limit
controller. The Imax current entered CO22 corresponds
to the maximum torque which the motor is able to
Example:
is set to the rated current of the connected motor, the motor
only be loaded with the rated torque.
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.

10.6 Adjustment of the torque controller
The torque controller must be set when the drive is load,
provided that there is a rising torque characteristic of the load over

Set the field frequency for the torque setting.
When the torque setpoint, a torque reserve must be
provided which depends on the acceleration time and the inertia.
For this, torque
must be established.
After the drive has accelerated to the frequency the

operating is reached. This is done by reducing the torque
at terminals 3 and 4.
