Description of Function R/W *
M1000
Operates monitor NO contact (contact a). NO while RUN, contact a. This contact
is On while in the RUN state.
RO
M1001
Operates monitor NC contact (contact b). NC while RUN, contact b. This contact is
Off while in the RUN state.
RO
M1002
Initiates a forward (the instant RUN is On) pulse. Initial pulse, contact a. Produces
a forward pulse the moment RUN begins; its width = scan cycle
RO
M1003
Initiates a reverse (the instant RUN is Off) pulse. Initial pulse, contact a. Produces
a reverse pulse the moment RUN ends; the pulse width = scan cycle
RO
M1004 Reserved RO
M1005 Driver malfunction instructions RO
M1006 Converter has no output RO
M1007 Driver direction FWD(0)/REV(1) RO
