Collective Break Error (KSP) (4)

Quote from Baig

Hi,

We are facing Collective Break Error (KSP) (4) on our KR C4.

Sometimes General Servo Error (1) and (4) also occur along with collective break error.

Have replaced the KPP and KSP2. Still alarm is there.

Any suggestions from anyone here??

Hi, check power supply connector for the brakes X3 for bad, burnt connection on CCU(A1) Power management board which goes from K2 filter and X34 (G1) KPP. Or even try and exchange the wires togehter with connectors.

Not long time ago I had issue due to poor connection on X3 connector with generating the similar error messages and the pin in the X3 started to get burned more more due to poor connection in one of the pins in X3 connector as seen in attached pictures. After replacing the wires and cleaning the pins on the board issue was cleared.
