CAUTION

Do not reset the inverter with the start signal on.

Otherwise, the motor will start instantly after resetting, which may lead to hazardous

conditions.

4.2.34 Alarm code output selection (Pr. 76)

Pr. 76 "alarm code output selection"

When an alarm occurs, its code can be output as a 4-bit digital signal from the open collector output

terminals. When programmed operation has been selected, this parameter also serves to output a group

operation signal.

The alarm code can read by a programmable controller etc to show its remedy on a display. Also you can

look at the progress of programmed operation.

0 Alarm code is not output. (Depends on Pr. 190 to Pr. 195).

When an alarm occurs, an alarm code signal is output. (Output signal is the same as in 1.)

When operation is normal, an operation status signal is output. (Output signal is the same as in 0.)

Note: 1. For alarm code definitions, refer to page 173.

2. The Pr. 76 setting overrides the Pr. 190 to Pr. 195 settings. Therefore, if you assign other signals

to output terminals SU, IPF, OL and FU using Pr. 190 to Pr. 195, these terminals provide the

output signals as listed above when any of "1 to 2" is set in Pr. 76. This should be noted when

using the functions which use the output signals to exercise control.
