You can set up the action during deceleration or after stalling when some
error occurs while either one of the protective functions of the driver is
triggered.
(DB: Dynamic Brake action)
<Caution>
The content of the deviation counter will be cleared when clearing the
alarm. Refer to P.43, "Timing Chart (When an error (alarm) occurs (at

–Sequence at
Servo-Off
You can set up,
1) the action during deceleration and after stalling
2) the clearing of deviation counter content,
after turning to Servo-OFF (SRV-ON signal : CN X5, Pin-29 is turned from
ON to OFF)
The relation between the setup value of Pr69 and the action/deviation
counter clearance is same as that of Pr67 (Sequence at Main Power Off)
Refer to P.44, "Timing Chart"-Servo-ON/OFF action while the motor is at
stall" of Preparation as well.
(DB: Dynamic Brake action)
<Caution>
In case of the setup value of 8 or 9, torque limit during deceleration will be
limited by the setup value of Pr6E (Torque setup at emergency stop).

action at stalling
You can set up the time from when the brake release signal (BRK-OFF :
CN X5, Pin-10 and 11) turns off to when the motor is de-energized
(Servo-free), when the motor turns to Servo-OFF while the motor is at
stall.
Refer to P.44, "Timing Chart"-Servo-ON/OFF Action While the Motor Is at
Stall" of Preparation as well.
• Set up to prevent a micro-travel/
drop of the motor (work) due to the
action delay time (tb) of the brake
• After setting up Pr6a
