1.8.8 Reset signal: Setting "10"

Used to reset the alarm stop state established when the inverter's protective function is activated. The reset signal immediately sets the control circuit to the initial (cold) status, e.g. initializes the electronic overcurrent protection circuit. It shuts off the inverter output at the same time. During reset, the inverter output is kept shut off. To give this reset input, short terminals RES-SD for more than 0.1 second. When the shorting time is long, the operation panel or parameter unit displays the initial screen, which is not a fault. Operation is enabled after terminals RES-SD are opened.

The reset terminal is used to reset the inverter alarm stop state. If the reset terminal is shorted, then opened while the inverter is running, the motor may be restarted during coasting (refer to the timing chart below) and the output may be shut off due to overcurrent or overvoltage.

Setting either of "1" and "15" in reset selection Pr. 75 allows the accidental input of the reset signal during operation to be unaccepted.

(For details, refer to page 94.)
