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 configura-
tion. 0.5A or larger is recommended.
• When this signal is connected to COM-, the dynamic brake will be re-
leased and the driver is enabled. (Servo-ON).
ÅE When Pr02 (Control Mode Selection) = 3, 4 or 5, the con-
trol mode is selected per the table below.
• If COM- is opened when the movable part of the ma-
chine has moved to CW exceeding the limit, the mo-
tor does not generate torque.
• If COM- is opened when the movable part of the ma-
chine 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 error counter can
be selected using Pr69 (Sequence under Servo-OFF).
