This document describes how to recover from a SRVO-038 Pulse mismatch alarm.The alarm is triggered when the encoder pulse count detected at power on is different from the one stored at power-off.

This can happen when the stored pulsecoder value is changed, for example by loading a backup.The error can also be triggered when the robot is moved while it is turned off, this can happen when the holding brake is defective on one of the axis.
