Project Planning for AC Motors
4Q operation with
brake and external
braking resistor
• 4Q operation with external braking resistor is recommended for applications in which
the level of regenerative energy is high.
• External braking resistors are only permitted with brake motors in combination with
brake control BGM/BSM.
• When using external braking resistors and BGM/BSM brake control, MOVIMOT
®
special functions must be activated. Refer to the MOVIMOT
®
operating instructions
for more information.
