18.5.2 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 776  Amplification low Current 777
 Current above P. 700 is in effect 775 > Current
> Current below P. 700 is in effect 757  Amplification 700
 Current > Current above P. 759 is in effect 758  Amplification high Current 759
By default, the parameters are preset such that the parameters are not active and only the basic
parameters are active.

18.5.3 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 624. Below 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
the Starting Current 623. In order to obtain torque controlled starting, the reference frequency
should be above the Frequency Limit 624. For example, this is guaranteed if Minimum Frequency
418 > Frequency Limit624.
f < Frequency Limit 624: Current impression
f ≥ Frequency Limit 624: Direct Torque Control DMR
The Frequency Limit 624 is set automatically during motor commissioning.
