Error messages

This page lists the error messages of the Epulse50 servo drive. When an error occurs, the drive reports the message and disables the power stage — the motor produces no torque.

All error messages disable the converter final stage (the motor has no torque). Type R alarms can be reset by the user, type B alarms are blockers. In the latter case, to reset the alarm, the converter must be switched off and on again (C2-16, CONTROL SUPPLY) to reset the alarm.

- The table lists the error codes, the alarm type (R = resettable, B = blocking), and the cause and remedy. - Type R alarms can be acknowledged and reset by the user after the cause has been removed. - Type B alarms require a power cycle (switching the control supply off and on) to reset. - Always remove the root cause before resetting the alarm; a repeated alarm indicates an unresolved fault.
