Remedy · Remède
1. Check whether the robot has collided with an object. If so, reset the system , then move the robot away from the location of the collision by jogging. 2. Check that the applied load does not exceed the maximum rating. If the rated load is exceeded, reduce the applied load. If the robot is used with an excessive load applied, the estimated disturbance might become excessively large, resulting in this alarm being output. 3. Check each interphase voltage of the three-phase voltage (200 VAC) applied to the servo amplifier. If the applied voltage is found to be 170 VAC or less, check the input power supply voltage. 4. Replace the servo amplifier.
