A less intuitive cause: A phase-to-ground short in the motor cable can create asymmetric voltage spikes that reflect back into the DC link, causing an overvoltage condition. This often triggers 607 alongside other faults like 608 or 314.
Proactive maintenance can nearly eliminate this fault: simodrive 611 error 607
: Measure the DC bus voltage and ensure the busbar screws are tight. A less intuitive cause: A phase-to-ground short in
: Inspect the motor power cables for breaks and ensure the terminals on both the motor and the Simodrive module are tight. simodrive 611 error 607
If the 48V supply drops below ~42V or is noisy, the drive cannot reliably activate the pulse enable. This is the of Error 607.
