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
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
SON
Servo ON
The servo remains ON while this signal is ON, or OFF while
this signal is OFF.
3.2.3
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 20 msec or longer, the
controller will write the current position in the specified
position field.
3.2.4
CLBR
Loadcell Calibration
Command
Turn this signal ON for more than 20ms to perform
calibration of loadcell.
3.2.7
Input
ST0 to ST6 Start Signal
The actuator moves to the commanded position with this
signal ON during the electromagnetic valve mode.
3.2.5
Signal with “*” expresses the signal of active low. In the controller, the process is held when the input signal is turned OFF.
