Tripping; Overview Of Operation Upon Tripping - Omron SYSDRIVE MX2 SERIES User Manual

3-4 Tripping

Upon detecting an error (overcurrent, overload, etc.) during operation, the Inverter cuts off the
output to the motor to protect the motor and Inverter. At the same time, the ALARM LED
indicator is lit and an error code is displayed. "Tripping" refers to this series of operations.
When a tripping occurs, the motor goes into free-run status. Identify the cause of the error from
the displayed error code, and remove the cause.
A RUN command is not accepted during a tripping. To reset a tripping, press the STOP/RESET
key. If a Reset (18: RS) is allocated to the multi-function input terminal, switching the reset
input from ON to OFF resets a tripping.
Note, however, that a tripping may not be reset depending on the cause of the tripping. In such
case, reconnect the power.
Also, confirm the RUN command and various other input signals thoroughly before executing
a reset. If the RUN command signal remains ON, the Inverter will restart immediately after the
reset.
