Power Failure Back-up Module
(with control power backup function)
DESCRIPTIONS
TMS01/032E
8.2 Control Sequence Diagram
8.2.1 Power ON Sequence
AC200V ON
Power supply to PSM
(AC200V) AC200V supplied from CX13
Power failure detection Power Failure Detection is available
(note 1)
1sec MIN.
CX17 Internal relay Internal relay is ON
*MCON signal
(CNC→SVM)
CX3 (PSM) Internal relay PSM internal relay is ON
MCC ON
DC link voltage
2200 ×=VDC
(VDC) Charging
1.5sec MAX.
*CRDY (PSM ready signal)
Sub Module C voltage VDC VDC×0.9
(Sub Module C TB1) Charging
60sec MAX.
RDY (CX16 B3) (note 2)
LED indication Blank “−” ”0”
Note 1) Power failure detection is available during PSM Ready signal (*CRDY) is “1”.
EXPFL (CX15) must be set “0” till power failure detection is started.
Note 2) Power failure backup operation is available when RDY =1. The operation which needs power
failure backup should be proceeded after the signal RDY goes “1”.
Without Sub Module C, RDY goes “1” simultaneously with *CRDY goes “0”.
