Changes in Output Targets for Fatal Fault Signal (MJA) of
Multi-function Output
Regarding the fatal fault signal (MJA) of multi-function output, the errors that can be output are changed
as follows. The fatal fault signal (MJA) turns ON when an alarm indicated with "Yes" in the table below
occurs.
The 3G3MX2-EV2 Series Inverter does not output the MJA when a Current detector error (E10), CPU
communications error (E22), or Main circuit error (E25) occurs. Refer to 7-8-19 Fatal Fault Signal (MJA)
on page 7-89 for information on the fatal fault signal (MJA) of multi-function output.
