Servo ON
When the SVON signal is ON, the product
is operational (Servo ON)
When the signal is OFF, the motor goes
into the free run state.
No
forward(CCW)
rotation
The motor is stopped so that the actuator
cannot rotate forward more than the set
motion window [0x2013] The set value
determines how it stops.
No
backwrad(CW)
rotation
The motor is stopped so that the actuator
cannot rotate reverse more than the set
motion window [0x2013] The set value
determines how it stops.
Alarm reset Turns off the Servo alarm.

operation
Intiatesoperation to the index position
operation.
Stop servo Stops operation.
Post-sensor
operation
If the index type is registration absolute
orregistration Relative, when the REGT
signal is on, the speed and distance is
changed to the preset speed and distance.
When the EMG signal is on, the servo

** PCON
P Control
Action
When the PCON signal is on, PI control
changes to P control.
** GAIN2
Gain 1,2
Transfer
When the GAIN2 signal is on, the speed
control changes from Gain 1 to Gain 2.
** PCL
Limit positive
torque
When the PCL signal is on, positive torque
is limited. [0x2110] You can preset the
action, and the torque limit is determined
by [0x2111].
