Connections and Settings in Torque Control Mode
The motor decelerates and stops as the dynamic brake (DB) is
operated. The motor will be in free condition after it stops.
Free running, the motor decelerates and stops. The motor
will be in free condition after it stops.
In this case, if you shut off the main power during Servo ON, it
will be SERVO-OFF without a trip. Then, when the main pow-
er supply turns ON again, it will be recovered to Servo ON.
Shutting off main power during Servo ON will activate ab-
normal main power supply under-voltage (alarm code
No.13) and cause a trip.
65 0 – 1 – Undervoltage
error response
at main power-off
The parameter sets whether to enable the “protection against main power
source under-voltage” function when you shut down the main power of
main and control power supplies.
Refer to the timing chart “At Power ON” of Preparations volume on page 40.
66 0 – 1 – Dynamic breke
inhibition at
overtravel limit
The parameter sets driving conditions at decelerated operation after over-
travel input inhibit (CCWL: connector CN X5 9-pin or CWL: connector CN
X5 8-pin) has been activated and enabled.

(2) Processing to clear content of the deviation counter
after the main power source is shut off.

• The parameter sets:
1) Driving conditions during deceleration or after stop
2) Processing to clear the deviation counter
following Servo off (SRV-ON signal: CN X5 29-pin turns On ‡ Off).
• A relationship between setting of Pr69 and driving conditions/deviation
counter processing conditions is similar to that of Pr67 (Sequence at
Main Power Off).
• See also “Serve On/Off Operation When the Motor Stops” of the timing
chart of Preparations volume on page 42.
