5.1.3 Alarm code output

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).

5.1.4 Resetting the inverter

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.

Operation 1: Using the operation panel (FR-DU04), press the [RESET] key to reset the inverter.

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

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