Brake Chopper Power Supply Not Present

What does PWR_+12V5 Off mean?

The PWR_+12V5 Green LED is OFF, indicating that the brake chopper power supply is not present. This condition means the 12.5V power rail required for the brake chopper operation is missing, which could impact the robot's ability to dissipate regenerative energy during braking. Without this power, the brake chopper cannot function.

• The +12.5V power supply to the brake chopper circuit is not present.
• No voltage detected on the +12.5V line supplying the brake chopper.
• Failure in the power source for the brake chopper control (e.g., fuse, regulator).
