Testing Motor with Brake without PLC
Hello everyone,
I’m having an issue with a SEW Eurodrive motor, model RF67 DT71D4/BMG/MM03, which is equipped with a BMG brake. The motor’s shaft is currently blocked, and based on the datasheet (page 14, link below), the brake seems to be the cause. Here’s the link to the full manual: SEW Eurodrive manual.
I’d like to test the motor by supplying it with three-phase power (L1, L2, L3 at 380V) to check its rotation in both directions. However, I’m unsure how to properly deactivate the brake before powering the motor because I don’t want to damage anything.
- How can I supply 24V to the brake so that it disengages and allows the motor to spin freely?
- Are there any precautions I should take to avoid making a mistake during this test?
Thanks in advance for your advice!
