Alarm Code Output Selection (Pr. 76) - Mitsubishi Electric FR-A520-0.4K Instruction Manual

4.2.33 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.

1 Alarm code bit 3
When an alarm occurs, an alarm code signal is output. (Output signal is the same as in 1.)
2
When operation is normal, an operation status signal is output. (Output signal is the same as in 0.)

(during programmed Output at time-out
operation)
Note: 1. For alarm code definitions, refer to page 203.
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 3" is set in Pr. 76. This should be noted when
using the functions which use the output signals to exercise control.
Example: When using the brake sequence functions (Pr. 278 to Pr. 285), assign the brake
opening request signal (BOF) to the RUN terminal by setting "20" in Pr. 190.
