Set the detection timing of the speed arrival output (AT-SPEED).
When the motor speed exceeds this setup value, the speed arrive output (AT-SPEED) is output.
Detection is associated with 10r/min hysteresis .

Motor brake delay time setup, mainly used to prevent servo on “galloping “phenomenon.
Set up the time from when the brake release signal(BRK-OFF) turns off to when the motor is de-energized
(servo-free),when the motor turns to servo-off while the motor is at stall
⚫
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 Pr4.37>=tb, then compose the sequence
so as the drive turns to servo-off after the brake is
actually activated.

Mechanical brake start delay time setup, mainly used to prevent servo off “galloping “phenomenon.
Set up time from when detecting the off of servo-on input signal(SRV-ON)is to when external brake
release signal(BRK-OFF)turns off, while the motor turns to servo off during the motor in motion.
⚫
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 Pr4.38 setup time, or time
lapse till the motor speed falls below Pr4.39 setup speed.
