1)
The rated DC voltage for the armature and field circuit is reached at an undervoltage of 5% of the
line side input voltage. If the rated supply voltage is applied to the input, a 5% higher output DC.
voltage is obtained. In conjunction with an undervoltage of more than 5% the output DC voltage
must be reduced linearly.

Conditions:
The control accuracy is referred to the rated speed of the drive and applies with the SIMOREG K
equipment at operating temperature. The following preconditions are applicable:
-
Temperature changes of ±10 K
-
Power supply voltage changes of +10% / -5% of the rated supply voltage
-
Load changes up to 100% of the maximum torque
-
Temperature-compensated tachometer with a temperature coefficient of 0.15
