FANUC Alarm SRVO-046 — SERVO OVC alarm (Group:%d Axis:%d)

Description

This alarm is issued to protect the motor when there is a danger of thermal destruction when the root-mean-square current value, calculated internally by the servo system , exceeds the maximum permissible value.

Remedy · Remède

1. Check the operating conditions of the robot. If the robot's ratings, such as the rated duty cycle and load, are exceeded, modify the use of the robot such that the rated values are not exceeded. 2. Check each interphase voltage of the three-phase voltage (200 VAC) applied to the servo amplifier connector CRR38A, which is 3-phase, and connector CRR39, which is singlephase. If the applied voltage is found to be 170 VAC or less, check the input power supply voltage. 3. Replace the servo amplifier. 4. If this does not clear the alarm, verify that all connectors are securely connected. 5. Replace the motor.
