Description
Specifies a delay between a close command (that is,
when the brake control output is de-energized) and
when the drive stops modulating. This is to keep the
motor live and under control until the brake actually
closes.
Set this parameter equal to the value specified by the
brake manufacturer as the mechanical make-up time
of the brake.
Brake close delay.
Defines the brake close speed as an absolute value.
After motor speed has decelerated to this level, a
close command is given.
Brake close speed.

If the internal brake chopper of the drive is enabled,
all energy fed by the motor to the drive is assumed to
be converted into heat, but the calculation still
records savings made by controlling the speed. If the
chopper is disabled, then regenerated energy from
the motor is also recorded here.
