Ackn. force controller error

Kuka · KRC2 KSS System Message

What does 2948 mean?

This is a follow-up message to the 'Force controller error' indicating that the force sensor signal does not match the motion. Error type 1: Actual force changes but position remains constant. Error type 2: Position changes but actual force remains constant. Error type 3: The gun opens further than the position corresponding to FORCE_LIM. These monitoring functions are only active during force control, resulting in dynamic braking, inhibition of active commands, and the 'ALARM_STOP' signal at level 0.

Common Causes

  • The force controller has detected an error and acknowledged it.
  • Internal fault within the force control loop.
  • Parameter misconfiguration affecting the force control algorithm.
