External I/O Circuits
Section 3-3
Control I/O Signals
The following table shows the names and functions of the Servo Drive's con-
trol I/O signals.
CN1 Control Input Signals
Pin No.
Symbol
Name
Function/Interface
1
+24VIN
12 to 24-VDC
Power Supply
Input
Power supply input terminal (12 to 24 VDC) for sequence inputs.
2
STOP
Emergency
Stop Input
Input for emergency stop.
When this signal is enabled and pin 1 is not connected to pin 2, an
Emergency Stop Input error (alarm code 87) occurs. Set this signal
to be enabled or disabled in the Emergency Stop Input Setting
(Pn041). (Factory default: Enable)
3
EXT3
External Latch
Signal 3
This external signal input latches the current value feedback pulse
counter.
The position data is obtained the moment the input is turned ON.
Minimal signal width must be 1 ms or more.
4
EXT2
External Latch
Signal 2
5
EXT1
External Latch
Signal 1
6
IN1
External Gen-
eral-purpose
Input 1
This input is used as external general-purpose input 1.
7
PCL
Forward Torque
Limit Input
When the Torque Limit Selection (Pn003) is set to 3 or 5, this signal
input selects the torque limit.
8
NCL
Reverse Torque
Limit Input
19 to 20
POT
Forward Drive
Prohibit Input
Forward, reverse drive rotation overtravel Input.
Pn004 chooses between enable and disable.
Pn044 sets the function assignment for pins 19 and 20.
Pn066 selects the operation.
NOT
Reverse Drive
Prohibit Input
21
DEC
Origin Proximity
Input
Connect the origin proximity input signal in the origin search opera-
tion.
Pn042 changes the logic of the sensor.
22
IN0
External Gen-
eral-purpose
Input 0
This input is used as external general-purpose input 0.
23
IN2
External Gen-
eral-purpose
Input 2
This input is used as external general-purpose input 2.
