<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 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).

C O M Å |
• 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.
SRV-ON
• When this signal is connected to COM-, the dynamic brake will be
released and the amplifier is enabled. (Servo-ON).
A-CLR
•
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.
INTSPD2
P o s i t i o n
• Clears the position error counter. Connect to COM-
c o n t r o l
to clear the counter.
• Use Pr4D to select the clear mode (0 Default: level 1: Edge)
Internal
• The internal velocity selection 2 (input) is valid. 4 kinds of
velocity
velocity settings are available by combination with DIV/
