P083, set according to source of the actual speed value
Rated motor
P100 =
Number of SIMOREG
P648, P649, set according to source of the control word
U807 = 0.000s telegram failure does not lead to a fault message
P110 = Actual armature resistance
x no. of SIMOREG converters
P111 = Actual armature
inductance
x no. of SIMOREG
converters
The optimization run for current
controller and precontrol
(P051 = 25) sets these parameters
correctly.
