4-2 Function Mode Reset •This function resets an Inverter trip. 4 Functions •To reset an Inverter trip, press the STOP/RESET key on the Digital Operator, or switch the RS terminal from ON to OFF. •To reset via the control circuit terminal block, allocate 18 (RS) to the desired multi-function input. •With reset frequency matching selection C103, you can select how to restart the Inverter after reset, a frequency matching or 0-Hz start. If an overcurrent trip occurs at frequency matching start, increase the retry wait time (b003). •You can select an alarm reset timing in reset selection C102. In addition, you can enable the reset signal only for alarm resetting during error.
•For the RS terminal, only NO contact is available. Note: Do not use the reset terminal to shut off the Inverter output. Reset operation clears the internal data (e.g. electronic thermal BRD counter), causing damage to the Inverter.
