By setting Pr. 76 "alarm code output selection", an alarm definition can be output as a 4-bit digital signal. This

signal is output from the open collector output terminals equipped as standard on the inverter.

Correlations between alarm definitions and alarm codes are as follows.

(Note) 0: Output transistor OFF, 1: Output transistor ON (common terminal SE)

The alarm output assumes that Pr. 195 setting is "99" (factory setting).

The inverter can be reset by performing any of the following operations. Note that the electronic overcurrent

protection's internal heat calculation value and the number of retries are cleared (erased) by resetting the

inverter.

It takes about 1s from when reset is canceled until operation is restored.

Operation 1: Using the operation panel (FR-DU04), press the 

 key to reset the inverter.

Operation 2: Switch power off once, then switch it on again.

Operation 3: Switch on the reset signal (RES).
