Alarm operation
H30 causes the inverter to generate a mock alarm in order to check whether external sequences function
correctly at the time of machine setup.
Setting the H30 data to "1" displays mock alarm err on the LED monitor. It also issues alarm output ALM (if
assigned to a digital output terminal specified by E06 or E07). (Accessing the H30 data requires simultaneous
keying of "
key +
key.") After that, the H30 data automatically reverts to "0," allowing you to reset the
alarm.
Just as for data (alarm history and relevant information) of those alarms that could occur in running the
inverter, the inverter saves mock alarm data, enabling you to confirm the mock alarm status.
To clear the mock alarm data, use H19. (Accessing the H19 data requires simultaneous keying of "
key +
key.") H19 data automatically reverts to "0" after clearing the alarm data.
