CN I/F Connector
Input Signals (Common) and their Functions
・Connect to (+) of an external power
supply(12VDC to 24VDC).
・Connect to (-) of an external power supply(12VDC to 24VDC).
・The required capacity depends on the I/O circuit
configuration. 0.5A or larger is recommended.
・When this signal is connected to COM-, the dynamic brake
will be released and the driver is enabled. (Servo-ON).
・When Pr02 (Control Mode Selection) = 3, 4 or 5,
the control mode is selected per the table below.
・If COM- is opened when the movable part of
the machine has moved to CW exceeding the
limit, the motor does not generate torque.
・If COM- is opened when the movable part of
the machine has moved CCW exceeding the
limit, the motor does not generate torque.
・When Pr04 (Overtravel Limit Input Disabled)
= 1, CW and CCW inputs are disabled.
・The dynamic brake can be made operable during CW/CCW
inputs valid. Use Pr66 (Dynamic Brake Inactivation at
Overtravel Limit) to make the dynamic brake operable.

1. This signal becomes effective about two seconds after
power on (see the Timing chart).
2. Don't use this Servo-ON or Servo-OFF signal to turn on
or off the motor.
・ Allow at least 50ms delay after the driver is enabled before any
command input is entered.
・ By opening the connection to COM- , the driver will be disabled(Servo-
OFF) and the current flow to the motor will be inhibited.
・Operation of the dynamic brake and clearing action of the position er-
ror counter can be selected using Pr69 (Sequence under Servo-OFF).
