Bits 7 and 8 of MP2195 enable you to deactivate the error messages that may be triggered by
the evaluation of these signals (PF.PS.AC, PF.PS.DC), without changing the SUPPLY.SPY table.
MP2195
Input:
July 2010
Note
Signals that change their status during operation are always identified as errors.
Only as of CC424 (B): Errors of the supply module (e.g. excessive Uz temp.) lead to an NC
stop (if M148 then LIFTOFF) with a subsequent emergency stop.
