Reset (Rs) - Omron 3G3MX2 User Manual

Reset (RS)

This function resets an Inverter trip.
To reset an Inverter trip, press the STOP/RESET key on the Digital Operator, or turn ON the
reset (RS) terminal.
When using the reset terminal, allocate "18: RS" to a multi-function input terminal.
The restart method to be applied after the reset operation can be selected by Reset Restart
Selection (C103). Take note, however, that the Inverter will restart at 0 Hz if Reset Selection
(C102) is set to "03: Trip reset only," regardless of the setting of C103. If an overcurrent trip
occurs at frequency matching, extend the Restart Standby Time (b003).
A trip reset time can be selected by Reset Selection (C102). In addition, the reset signal can
be applied only to trip reset due to an error.
For the Reset (RS) terminal, only the NO contact setting is effective.
Do not use the reset terminal to stop the Inverter output. The reset operation will clear various data
such as electronic thermal function and usage rate counter for regenerative braking, thereby
causing damage to the Inverter.
