Relevant
Sections
CSTR
PTP strobe
(Start signal)
The actuator will start to move to the position set by the
command position number.
3.2.4
PC1 to
PC256
Command position
number
Input (in binary) a number of the position that is desired to move. 3.2.4
BKRL Brake forcible release The brake will forcibly be released. 3.2.3
RMOD
Operation mode
changeover
The operating mode is selectable when the MODE switch of the
controller is set to AUTO.
(The setting is AUTO when signal is OFF, and MANU when ON.)
3.2.3
*STP Pause
When this signal turns OFF while the actuator is moving, the
actuator will decelerate to stop. The remaining
movement is in a hold while the actuator is stopped and will
resume when the signal turns back ON.
3.2.4
3.2.5
3.2.6
RES Reset
An alarm will be reset when this signal is turned ON. Also, when
it is turned ON in the pause mode (*STP is turned OFF), the
remaining movement amount can be cancelled.
3.2.3
3.2.4
3.2.5
3.2.6
SON Servo ON
The servo remains ON while this signal is ON, or OFF while this
signal is OFF.
3.2.4
HOME Home return
The controller will perform home return operation when this
signal is turned ON.
3.2.3
MODE Teaching mode
The operating mode will change to the teaching mode when this
signal is turned ON. The mode will not be switched over unless
CSTR, JOG+ and JOG- are all OFF and the actuator operation is
stopped.
3.2.4
JISL Jog/inching selector
Jog Operation can be performed with JOG+ and JOG- while this
signal is OFF.
Inching Operation is performed with JOG+ and JOG- when it is
ON.
3.2.4
JOG +
JOG -
Jog
Jog Operation is performed to positive direction by detecting ON
edge of JOG+ signal and to negative direction by JOG- signal
while JISL signal is OFF.
The actuator will decelerate and stop if OFF edge is detected
while in each Operation.
Inching Operation is performed while JISL signal is ON.
3.2.4
PWRT Current Position Write
When the write position is specified in the teaching mode and
this signal has remained ON for 26msec or longer, the controller
will write the current position in the specified position field.
3.2.4
Input
ST0 to ST6 Start Signal
The actuator moves to the commanded position with this signal
ON during the solenoid valve mode.
3.2.5
3.2.6

Signal with “*” expresses the signal of active low. In the controller, the process is held when the input signal is turned OFF.
