Operation can be switched between a status signal
(high level) and a differential signal (rising edge) us-
ing bit A in setup parameter Cn-02.

PCL/SPD1
Forward rotation current
limit input / Speed selec-
tion command 1 input
Forward/reverse rotation current limit (PCL/NCL)
when setup parameter Cn-02 bit no. 2 = 0.
(ON: Current limit)
12
NCL/SPD2
Reverse rotation current
limit input / Speed selec-
tion command 2 input
(
)
Internal setting speed (Cn-1F, 20, 21) selector switch
when setup parameter Cn-02 bit no. 2 = 1.
13
+24VIN
+24-V power supply input
for control DC
Power supply for pin nos. 11, 12, 14, 15, 16, 17, 18;
+24-V input
14
RUN
Run command input
ON: Servo ON, when setup parameter Cn-01 bit no.
0 = 0.
0
0.
When setup parameter Cn-01 bit no. 0 = 1, this sig-
nal is not used. (Automatically set to Servo ON.)
15
MING
Gain deceleration input
ON: Decrease speed loop gain, when setup parame-
ter Cn-02 bit no. 2 = 0 and Cn-01 bit no. F = 0.
IPG
(HA/LA/V/W
Models)
Pulse stop input
ON: Stop input command pulses, when setup pa-
rameter Cn-02 bit no. 2 = 0 and Cn-01 bit no. F = 1.
RDIR
Rotation direction com-
mand inputs
When setup parameter Cn-02 bit no. 2 = 1, this is
the rotation direction command for internal speed
settings 1 to 3. (OFF: Forward, ON: Reverse)
16
POT
Forward drive prohibit in-
put
Forward rotation overtravel input (OFF when prohib-
ited). When setup parameter Cn-01 bit no. 2 = 1, this
signal is not used.
17
NOT
Reverse drive prohibit in-
put
Reverse rotation overtravel input (OFF when prohib-
ited). When setup parameter Cn-01 bit no. 3 = 1, this
signal is not used.
18
RESET
Alarm reset input
ON: Servo alarm status is reset.
