12. WHEN USING WITH A GENERAL-PURPOSE INTERFACE
12 - 83
Note 1. When the rest of command travel distance is other than "0", ST1 (Forward rotation start) is not received. Refer to section
12.6.5 (1).
2. RT (Second acceleration/deceleration selection) will not be accepted during operation. Selection of the servo motor speed and
acceleration/deceleration time constants will be enabled by on-edge of ST1 (Forward rotation start). However, when the rest of
command travel distance is other than "0", ST1 (Forward rotation start) is not enabled even if turned on.
3. Counting will start when the rest of command travel distance becomes "0".
4. When MEND (Travel completion) is off, the station position outputs will be "0" (all off).
5. Up to four points of DO are available; therefore, PS0 to PS7 cannot be outputted simultaneously.
12.6.3 Manual operation mode
POINT
When the operation mode is changed during operation, inputting ST1 (Forward
rotation start) is disabled until the operation stops. Switch on ST1 (Forward
rotation start) after the operation stops.
For the machine adjustment, home position adjustment, and others, you can shift the position to any position
with the station JOG operation or JOG operation.
(1) Station JOG operation
(a) Setting
Set devices and parameters as shown below depending on the intended application. With this
operation, DI0 (Next station No. selection 1) to DI7 (Next station No. selection 8) are disabled.
Item Device/parameter to be used Setting
Selecting indexer method Control mode selection of [Pr. PA01] Select "_ _ _ 8" (positioning mode (indexer method)).
Manual operation mode
selection MD0 (Operation mode selection 1) Switch on MD0.
MD1 (Operation mode selection 2) Switch off MD1.
Station JOG operation
selection [Pr. PT27] _ _ 0 _: Select Station JOG operation.
Rotation direction selection SIG (External limit/Rotation direction decision/
Automatic speed selection) The rotation direction to a station No. will be as
follows.
Off: Station No. decreasing direction
On: Station No. increasing direction
Servo motor speed [Pr. PC07] Set a servo motor speed.
Acceleration time constant/
Deceleration time constant RT (Second acceleration/deceleration
selection) 1. When RT is turned off
Acceleration time constant: setting value of [Pr.
PC01 Acceleration time constant 1]
Deceleration time constant: setting value of [Pr.
PC02 Deceleration time constant 1]
2. When RT is turned on
Acceleration time constant: setting value of [Pr.
PC30 Acceleration time constant 2]
Deceleration time constant: setting value of [Pr.
PC31 Deceleration time constant 2]
