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.
Ni After setting up Pr4.37>=tb, then
compose the sequence so as the driver
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

When servo off, rotate speed less than this setup vale, and mechanical brake start delay
time arrive, motor lost power.
