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 Handling of status signals from HEIDENHAIN power supply units
Input:
Bit 0 - status signals that are already active during control power-up
0: Missing signals are ignored
1: Missing signals are evaluated
Bit 1 - ERR.UZ.GR
signal
0: Error message is not suppressed
1: Error message is suppressed
Bit 2 - ERR.TMP
signal
0: Error message is not suppressed
1: Error message is suppressed
Bit 3 - reserved
Bit 4 - ERR.IZ.GR
signal
0: Error message is not suppressed
1: Error message is suppressed
Bit 5 - RDY.PS signal
0: Error message is not suppressed
1: Error message is suppressed
Bit 6 - ERR.ILEAK
signal
0: Error message is not suppressed
1: Error message is suppressed
Bit 7 - PF.PS.AC
0: Previous behavior; Error message is not suppressed
1: Error message is suppressed
Bit 8 - PF.PS.DC
0: Previous behavior; Error message is not suppressed
1: Error message is suppressed
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.
