• 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 amplifier is enabled. (Servo-ON).

•

If the COM- connection is kept closed for more than 120 ms,

the alarm status will be cleared.

•

Some alarms cannot be cleared by this input.

For details, see Protective Functions on page 60.

The function differs depending on the control mode.

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 App.8)

• Allow at least 100ms delay after the amplifier is enabled before any

command input is entered.

• By opening the connection to COM- , the amplifier 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 (0 Default: level 1: Edge)
• The internal velocity selection 2 (input) is valid. 4 kinds of

velocity settings are available by combination with DIV/
INTSPD1 input. See control mode setting Pr02 (APP. 16).
