Operating Procedure
In positioning control, operation is started up, stopped normally, and stopped in
emergencies by the ON/OFF status of special utility relays.
The table below shows the relationship between operations and the special utility
relays used.

■ Operation chart
Note 1: If there is no error in the parameter setting when special utility relay 2310
turns ON at startup of the clock pulses, special utility relay 2309 turns ON and clock
pulses are output.
Note 2: If there is an error in the parameter setting, special utility relay 2309 does
not turn ON but a corresponding error code is written to DM1486.
Confirm the error code, and change the erroneously set parameter.
Note 3: By setting special utility relay 2309 to OFF in an interrupt program, clock
pulses can be immediately stopped.
Note 4: Rising of special utility relay 2310, falling of special utility relay 2309, and
rising of special utility relay 2308 are performed by end processing and RETI.
(Special utility relay 2309 turns ON at that time.)
Note 5: It takes a maximum of 10 ms from when special utility relay 2310 turns ON
until pulses are output.
Note 6: Even if special utility relay 2310 is set to ON while special utility relay 2308
or 2309 is ON, it is ignored.
Note 7: When pulse output has finished, special utility relay 2309 is immediately set
to OFF (without regard to the scan time).

When relay 2310 turns ON, clock pulses are
output (detection at rising edge).
While clock pulses are output, relay 2309
remains ON. While clock pulses are not
output, relay 2309 remains OFF.
When relay 2308 turns ON, clock pulses are
decelerated and stopped (detection at rising
edge).
