This section explains the function inputs that can be allocated to the general-purpose inputs.
 Error Stop Input (ESTP)
• This signal is used to forcibly generate an error to stop motor rotation from an external device.
• If the Error Stop Input (ESTP) signal turns ON during motor rotation, the Servomotor stops
according to the setting in the Stop Selection - Fault Reaction Option Code (3B20-04 hex).
• If the Error Stop Input (ESTP) signal turns ON when the Servomotor is energized, the Error Stop
Input (Error No. 87.00) will occur.
 Positive Drive Prohibition Input (POT) and Negative Drive Prohibition Input
(NOT)
• These two input signals prohibit the positive and negative drive (over-travel).
• When these terminals are short-circuited (default setting), the Servo Drive can drive the Servomo-
tor in each rotation direction.
• In the drive prohibition state, the Servo Drive does not enter an error state.
• To use this function, set
Drive Prohibition - Enable (3B10-01 hex) to 1 .
• When Drive Prohibition - Enable (3B10-01 hex) is set to 1 , you can select the operation at a
drive prohibition input in Drive Prohibition - Stop Selection (3B10-02 hex).
 Home Proximity Input (DEC)
• This is the deceleration signal for homing.
• If the Home Proximity Input turns ON while the Servomotor is running at the
Speed During
Search for Switch (3A00-03 hex), it will decelerate to Homing - Speed During Search for Zero
(3A00-04 hex).
 External Latch Input (EXT1 and EXT2)
• These are the external input signals to latch the present position.
• The encoder position data is obtained at the rising edge when the External Latch Input is turned
ON.
 Monitor Inputs (MON1 to MON8)
• These can be used as general-purpose monitor inputs.
• The general-purpose monitor inputs do not affect operation, and they can be monitored from the
host controller.
 Positive Torque Limit Input (PCL) and Negative Torque Limit Input (NCL)
• The Positive Torque Limit Input (PCL) is used to switch the torque limit between the Positive
torque limit value (60E0 hex or 3330-03 hex) and Positive Torque Limit Value 2 (3330-05 hex).
• The Negative Torque Limit Input (NCL) is used to switch the torque limit between the Negative
torque limit value (60E1 hex or 3330-04 hex) and Negative Torque Limit Value 2 (3330-06
hex).
• Use the Torque Limit - Switching Selection (3330-01 hex) to select a method to switch the
torque limit.
