Reset method of protective function

4.3 Reset method of protective function

(1) Resetting the inverter
The inverter can be reset by performing any of the following operations. Note that the internal thermal integrated value
of the electronic thermal relay function and the number of retries are cleared (erased) by resetting the inverter.
Recover about 1s after reset is cancelled.
Operation 1: ..... Using the operation panel, press
(Enabled only when the inverter protective function is activated (major
fault) (Refer to page 239 for major fault.))
Operation 2:...... Switch power off once, then switch it on again.
Operation 3: ..... Turn on the reset signal (RES) for more than 0.1s. (If the RES signal is
kept on, "Err." appears (flickers) to indicate that the inverter is in a reset
status.)
REMARKS
For the 01800 or more, you can set Pr. 75 to disable reset operation until the thermal cumulative amount reaches 0 when a
thermal trip (THM, THT) or an overcurrent trip (OC1 to OC3) occurs consecutively twice. (Refer to
(applied).)
