– 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

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 >

then compose the sequence so as
the driver turns to Servo-OFF after
the brake is actually activated.
