The cable should be as short as possible, and the cable cross section should correspond to the
national/international regulations so that the voltage supply at the rectifier does not deviate
from the rated voltage by more than ±2 %.
If the drum motor with electromagnetic brake is used at an ambient temperature below +5 °C,
a special oil must be used. In case of doubt, contact Interroll.
The electromagnetic brake is a pure holding brake and should not be used for positioning or
braking the motor. Positioning applications should be implemented with a frequency inverter in
conjunction with an encoder integrated in the motor. Braking applications should be implemented
with a frequency inverter.
