• Connect to (+) of an external power supply (12VDC to
24VDC).
• Use source voltage of 12V
±
10% – 24V
±
10%.
• 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.
• If you set 1 to Pr04 (Overtravel input inhibited invalid), CWL/CCWL
input will be disabled. A factory setting is Disable (1).
• With Pr66 (DB deactivate when driving is inhibited), you can
activate dynamic brake when CWL/CCWL input is enabled.
According to a factory setting, dynamic brake operates
(Pr66 is set to 0).
The function differs depending on the control mode.
<Notes>
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. See page
46 "Dynamic Brake" in Preparations.
• 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).

• Clears the position error counter.
Connect to COM– to clear the counter.
• Use Pr4D to select the clear mode.
• With speed setting of the 2nd selection input, you can set 4
speeds in combination with INH.
