Stopped (Axis Number)

What does 1100 mean?

This message on the KUKA KRC4 KSS 8.3 system indicates that a specific axis ('{(Axis number)}') has unexpectedly stopped or entered a prolonged standstill condition, typically triggered by the internal standstill monitoring function. This can occur due to external impedance, loss of motion command, or incorrect monitoring sensitivity, particularly when in torque mode.

• An uncommanded stop or hold condition for the specified axis, possibly due to external intervention or safety interlock.
• External mechanical obstruction or collision causing the axis to cease movement during an active motion command.
• Activation of an emergency stop, safety stop, or power loss event affecting the motor or drive of the identified axis.
• The standstill monitoring parameters are too sensitive for the current application's motion profile or for torque mode operation.
• An internal drive fault, motor issue, or brake malfunction preventing the axis from responding to commanded movements.

Click steps to track your progress.

1. 1

   Review the robot program and execution context to confirm that an intentional stop or hold command for the specified axis is not active.

2. 2

   Thoroughly inspect the robot's work envelope and the affected axis ('{(Axis number)}') for any mechanical obstructions, collisions, or binding.

3. 3

   Check the status of all safety circuits, emergency stop devices, and external safety stops to ensure they are not active and preventing motion.

4. 4

   If in torque mode, verify that SET_TORQUE_LIMITS(..., monitor #OFF) is active if regular standstill monitoring is intended to be suppressed.

5. 5

   Use the KUKA HMI's diagnostic monitor to check the real-time status, commanded velocity, and actual velocity of the drive associated with the affected axis.
