Permitted pulse voltage for EDR../EDRN.. motors
INFORMATION
The permitted maximum PE voltage of 1200 V must not be exceeded in IT system
operation even in the event of an error.
INFORMATION
If the permitted pulse voltage is exceeded, you have to provide for according meas-
ures to limit it. Consult the manufacturer of the inverter.
INFORMATION
The maximum permitted nominal motor voltage for inverter operation is 500 V.
