What the Fault Means

Fault: Braking resistor phase failure

Likely causes

  • A phase failure for the brake resistor was detected
  • Fault value (r0949, interpret decimal): 11: Phase U 12: Phase V 13: Phase W See also: p3235 (Phase failure signal motor monitoring time)

Solution and Safe First Checks

  1. Check the feeder cables to the braking resistors.

Safety: do not work inside the panel without isolating the power; if unsure, consult a qualified technician.
