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

You can 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
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) 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.
