Alarm KRC0047

KUKA Robot KRC0047 - i2t MONITORING, CURRENT LIMIT OF THE MOTOR CABLE <string1> AFTER <string2> s EXCEEDED 100

The motor cable current limit has exceeded 100 percent of the maximum permissible threshold after the specified time duration, indicating severe axis overload. The robot must be immediately halted and the payload or motion profile must be reduced to prevent thermal damage to the motor and cable.

KUKA Robot KRC0047 - i2t MONITORING, CURRENT LIMIT OF THE MOTOR CABLE <string1> AFTER <string2> s EXCEEDED 100

i2t MONITORING, CURRENT LIMIT OF THE MOTOR CABLE <string1> AFTER <string2> s EXCEEDED 100

The motor cable current limit has exceeded 100 percent of the maximum permissible threshold after the specified time duration, indicating severe axis overload. The robot must be immediately halted and the payload or motion profile must be reduced to prevent thermal damage to the motor and cable.

Common Causes

  • Payload mass exceeds the rated maximum for the specific robot axis
  • Motion velocity or acceleration parameters set beyond recommended limits in machine data
  • Mechanical friction or binding in the axis joint due to wear, contamination, or misalignment
  • Insufficient cooldown time between consecutive high-load operations causing cumulative thermal stress
  • Gravitational load holding requirements on vertical axes without adequate counterbalance settings

Troubleshooting Steps

  1. 1Immediately stop the robot program and bring all axes to a safe standstill using SafeOperation procedures
  2. 2Check the actual payload mass on the tool flange and compare against the axis load rating in the technical specifications
  3. 3Review the $CURR_MON[] machine data array in WorkVisual to understand the threshold limits for each motor cable
  4. 4Reduce motion acceleration and velocity parameters in the KRL program and retune using WorkVisual calibration tools
  5. 5Inspect the axis mechanical components for signs of binding, bearing wear, or contamination and service if required
  6. 6Allow adequate cooldown periods between high-load cycles and implement duty cycle monitoring using KUKA diagnostics
