Control Input Details
This is the detailed information about the CN1 connector input pins.
General-purpose Inputs (IN1 to IN8)
Note: The functions that are allocated by default are given in brackets.
Refer to
7-1 Sequence I/O Signals on page 7-1 for the allocation procedures.
Immediate Stop Input (STOP)
 STOP is used when an external sequence such as the host forcibly turns OFF the servo.
 If the Immediate Stop Input (STOP) turns ON during the Servomotor rotation, the dynamic brake
makes a deceleration stop. After the motor stops, it remains in servo-free state.
 If the Immediate Stop Input (STOP) turns ON when the motor is energized, an Immediate Stop
Input Error (Error No. 87.0) will occur.
 This input is allocated to the pin 5 with the NC contact in the default setting.
Precautions for Safe Use
Turn ON the Immediate Stop Input (STOP) at the same time when you turn OFF the main
power. When the main power turns OFF due to an external immediate stop, the motor will
continue to rotate due to residual voltage. This may cause human injuries or damages to the
machine and devices.
