Brake Abnormal

¿Qué significa SRVO-018 ?

An excessive current is detected in the motor brake circuit, and the ALM LED (SVALM) on the 6-Axis servo amplifier is illuminated. This can be caused by a short circuit or ground fault in the brake wiring, or an optional brake release unit being left active while attempting robot motion.

• The brake system on an axis is reporting an abnormal condition.
• This could indicate that the brake is not engaging or disengaging correctly, or that there is a fault with the brake control circuit.
• The servo drive may not be receiving the correct brake status feedback.
• Requires checking brake power, wiring, and the brake mechanism itself for mechanical issues.

1. 1

   Check the robot connection cable (RMP1, RP1) and the internal cable of the robot and motor brakes connected to CRR88 connector on the 6-Axis servo amplifier for a short-circuit or grounding fault. If found, replace the failed part.

2. 2

   Check the cables and motor brakes connected to CRR65A, CRR65B connector on the 6-Axis servo amplifier for a short-circuit or grounding fault. If found, replace the failed part.

3. 3

   If using an optional brake release unit, turn off its on/off switch and cycle the controller power.

4. 4

   Replace the 6-Axis servo amplifier.
