You can set up,
1) the running condition during deceleration and after stalling
2) the clear treatment of deviation counter is set up. 
After the servo-ON signal input is turned off (SRV-ON : CN X5, Pin-23
shifting from ON to OFF).
The relation between the setup value of SV.Pr69 and the action/deviation
counter clearance is same as that of SV.Pr67 (Error response at main
power-off).
Refer to P.135, "Timing Chart"-Servo-ON/OFF action while the motor is at
stall" of Operation Setting as well.

standstill
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.135, "Timing Chart"-Servo-ON/OFF Action While the Motor Is
at Stall" of Operation Setting as well.
• Set up to prevent a micro-travel/
drop of the motor (work) due to the
action delay time (tb) of the brake

delay at motor in

You can set up time from when detecting the off of Servo-ON input signal
(SRV-ON : CN X5, Pin-29) is to when external brake release signal
(BRK-OFF : CN X5, Pin-10 and 11) turns off, while the motor turns to
servo off during the motor in motion.
Refer to P.135, "Timing Chart"-Servo-ON/OFF action while the motor is in
motion" of Operation Setting as well.
• Set up to prevent the brake
deterioration due to the motor
running.
• At Servo-OFF during the motor is
running, tb of the right fig. will be
a shorter one of either SV.Pr6B
setup time, or time lapse till the
motor speed falls below 30r/min.
