KPS Ballast Switch Overload During Operation
Kuka · KR C2 Robot Controller
Was bedeutet Ballast switch energized for too long PMx ?
The brake resistor experienced an I²t overload during operation. This indicates that the ballast switch was energized for an excessive duration. Possible causes include a defective or incorrectly connected ballast resistor, or deceleration phases in the robot program that are too long.
Häufige Ursachen
- Ballast switch in KPS remains energized for too long during normal operation.
- Faulty ballast switch not de-energizing correctly.
- Control signal for the ballast switch is stuck 'on'.
- Overcurrent condition detected through the ballast switch.
Reparaturschritte & Checkliste
Klicken Sie auf Schritte, um Ihren Fortschritt zu verfolgen.
- 1
Check the ballast resistor for defects, including open circuits or incorrect resistance values.
- 2
Verify the correct wiring and connection of the ballast resistor to the KPS module.
- 3
Review the robot program for excessively long or frequent deceleration phases and adjust if necessary.
- 4
Consider implementing an energy recovery unit to manage regenerative energy and reduce stress on the ballast resistor.
