Limit for detection of acceleration process

Minimum Deviation for Comp. Acceleration
Via Parameter
process is detected. Acceleration pre-control via Parameters 870 and 871 will only be activated when
the deviation between ramp input and ramp output is greater than Parameter 869.
Parameter 869should be set such that small variations of the reference speed do not result in narrow
"needles" in the reference torque. Minor reference value variations normally are no intended change
of the reference value, but are caused by noise in the analog reference value or changing diameters in
operation.

Current limitation

Current Limit for Compensation
Via Parameter
compensation calculator can be limited. The compensation calculator outputs a torque-forming current
component, Parameter 872 only refers to this component.
The total current is set accordingly, depending on the parameterized magnetizing current and the
output of the speed controller. The outputs of the compensation calculator and speed controller to-
gether form the reference value
