KPS Ballast Switch Overload During Operation

What does Ballast switch energized for too long PMx mean?

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.

1. 1

   Check the ballast resistor for defects, including open circuits or incorrect resistance values.

2. 2

   Verify the correct wiring and connection of the ballast resistor to the KPS module.

3. 3

   Review the robot program for excessively long or frequent deceleration phases and adjust if necessary.

4. 4

   Consider implementing an energy recovery unit to manage regenerative energy and reduce stress on the ballast resistor.
