mode
1 EXT1 External latch signal 1 input An external interrupt input signal.
Use as an external interrupt signal for
interrupt feeding or as external origin
input signal for origin searches. The
signal is valid when ON.
Position
2 DEC Origin proximity input The origin proximity input signal for ori-
gin searches.
The signal is valid when ON.
All modes
3 NOT Reverse drive inhibit input The limit input in the reverse direction.
This input operates as follows (i.e., like
a NC contact):
OFF: Drive prohibited, ON: Drive
enabled All modes
4 POT Forward drive inhibit input The limit input in the forward direction.
This input operates as follows (i.e., like
a NC contact):
OFF: Drive prohibited, ON: Drive
enabled All modes
5 +24VIN +24-V power supply input for
control DC The +24 VDC input terminal for the con-
trol input power supply. All modes
6 STOP Emergency stop input An external input signal used to stop
power supply to the motor.
This input is used when an error occurs
to unlock the Servo from a host control-
ler.
This input operates as follows (i.e., like
a NC contact):
OFF: Power to motor stopped (Servo
cannot be locked).
ON: Power can be supplied to motor
(Servo can be locked).
