SIMODRIVE 611U 617: DC Link Overvoltage

What 617 means

The DC link voltage rose above the upper limit, usually from braking energy.

Symptoms

Trips when axes decelerate hard.

Is it repairable?

Yes: infeed and resistor modules are repairable.

Common causes

  • Braking energy too high for the regen or braking resistor
  • High line voltage
  • Failed pulse resistor or infeed module

Safe checks

  1. 1Check the line voltage
  2. 2Reduce the deceleration as a test
  3. 3Check the pulsed resistor module or regenerative infeed

Drives hold dangerous voltage after power-off. Checks should only be done by qualified personnel, with power isolated and the DC link discharged.

Reviewed by AutomIQ repair technicians. Code and name from the SIMODRIVE 611 universal Function Manual.
