The value for parameter P-0-0018, Number of pole pairs/pole pair
distance has to be taken from the completed form "Output Data for
Asynchronous or Synchronous Motors".
The velocity command value that is output by the controller is limited to
this value of parameter S-0-0113, Maximum motor speed. The value
mustn't be higher than the maximum allowed velocity (speed)!
The motor current at standstill is the rms value of the torque-generating
component of the continuous motor current.
The value entered in parameter S-0-0111, Motor current at standstill is
the 100% reference value for the torque/force limit parameters S-0-0092
and P-0-0109 with percentage-based scaling (see below).
