Advanced current controller

In some machines, it may be necessary to set different amplification factors for different current
ranges.
Definition:

Current
< Current below P. 777 is in effect

Current above P. 700 is in effect
>
Current below P. 700 is in effect


Torque controller

The torque-controlled Configurations 230, 430, 530 and 630 enable sensor-less torque control as an
alternative to speed control. Torque control is possible above the
frequency limit, current impression is active at the current reference frequency as the reference
frequency. In this case, the torque is not controlled but is set depending on the load behavior and
