Servo-OFF

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.

delay at motor

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

• After setting up SV.Pr6a

tb , 

then compose the sequence so as

the driver turns to Servo-OFF after

the brake is actually activated.

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.
