Input devices
The following devices can be assigned to any connector pins among CN1A-8, CN1B-5, 7, 8, 9, 14, 15, 16, 17
and CN1A-19 (when the input device is selected using the parameter). Automatic ON setting can also be
made using parameters.
Signal Name Abbreviation Description
No assigned
function
Function is not assigned.
Forced stop EMG
Forced stop input device.
Opening EMG-SG results in a forced stop status, switching off the servo
amplifier and operating the dynamic brake.
When EMG-SG are shorted in the forced stop status, the forced stop status can
be reset.
Servo-on SON
Operation ready signal input device.
Shorting SON-SG switches on the base circuit.
Opening SON-SG shuts off the base circuit and coasts the servo motor.
Alarm reset RES
Alarm reset signal input device.
Shorting RES-SG at alarm occurrence resets the alarm. By setting parameter
No. 55 (OP6), the base circuit can be shut off when RES-SG are shorted.
The following alarms cannot be reset:
Also, the regenerative alarm (AL. 30), overload 1 (AL. 50) and overload 2 (AL.
51) cannot be reset until the power transistor is cooled to proper temperature.
Forward
rotation stroke
end
LSP
Forward rotation stroke end signal input device.
Opening LSP-SG disables operation in the CCW direction. Operation can be
performed in the CW direction.
To perform CCW operation, short LSP-SG with the limit switch.
Reverse rotation
stroke end
LSN
Reverse rotation stroke end signal input device.
Opening LSN-SG disables operation in the CW direction. Operation can be
performed in the CCW direction.
To perform CW operation, short LSN-SG with the limit switch.
Forward
rotation start
ST1
Forward rotation start signal input device.
Shorting ST1-SG in the automatic operation mode starts forward rotation on its
leading edge.
Shorting ST1-SG in the home position return mode starts a home position
return on its leading edge.
Shorting ST1-SG in the jog feed mode starts forward rotation jog.
Note. Forward rotation indicates an address increasing direction.
Reverse rotation
start
ST2
Reverse rotation start signal input device.
Shorting ST1-SG in the automatic operation mode starts reverse rotation on its
leading edge.
Shorting ST1-SG in the jog feed mode starts reverse rotation jog.
Note. Reverse rotation indicates an address decreasing direction.
Automatic/man
ual selection
MD0
Automatic/manual mode selection signal input device.
Shorting MD0-SD chooses the automatic operation mode, and opening them
chooses the manual operation mode.
Proximity dog DOG
Proximity dog signal input device.
Proximity dog signal for a manual home position return.
Shorting DOG-SG turns on the proximity dog signal.
