Hi toby,

SRVO-043 SERVO DCAL alarm

Cause: The regenerative energy produced by the motor, exceeded specification.

Remedy: If a 4 is indicated on the servo amplifier LED, a DCSW condition exists. DCSW alarm occurs when the regenerative transistor is on for one second or longer. To repair a DCSW, replace the servo amp. If problem persists, the load of the robot may exceed the specification. If a 5 is indicated on the servo amplifier LED, a DCOH condition exists. DCOH alarm occurs when the regenerative resistor overheats and is sensed by the thermostat. The average regenerative energy is excessive, relax the operating conditions. If using a separate regenerative discharge unit, check the wiring or replace.

Happy Learning!

Thanks mate , 

I will try this .
