9.2.5 Voltage constant
In configuration 5xx for the control of synchronous machines, the control behavior
can be improved for high dynamic requirements by the settings of the parameter
Voltage constant
383.
For the voltage constant, refer to the motor data sheet. In the motor data sheet, the
value may be indicated in
rpm 1000
V
. This value can be taken over for parameter
Voltage constant
383.

383 Voltage constant 0.0 mVmin 850.0 mVmin 0.0 mVmin
9.2.6 Stator inductance
In configuration 5xx for the control of synchronous machines, the control behavior
can be improved for high dynamic requirements by setting the parameter
Stator in-
ductance
384.
The
stator inductance
384 is the value between two motor phases and can be taken
usually from the data sheet of the motor.

9.2.7 Peak current
The parameter
Peak Current
1192 is used during the guided commissioning to set
the limits for the Isq set value in the frequency inverter. This serves the protection of
the connected synchronous motor. The value can be taken from the motor name
plate or the motor data sheet. Exceeding the values given by the motor manufacturer
can lead to damages in the motor.
