Description of choices:
Free-wheeling stop: Selected if the fre-
quency converter is to "release" the motor
which then runs freely until it stops. Logical
"0" will lead to free-wheeling stop.
Quick stop: Selected if the motor is to be
stopped according to alternative ramp time
in parameter 218. Logical "0" will mean
quick stop.
D.c. brake: Selected if the motor is to be
stopped by impressing a D.C. voltage to
the motor for a certain period as selected
in parameters 306 and 308. The function is
only active when the value in parameters
306 and 308 is different from 0. Logical "0"
will lead to D.C. braking.
Reset and free-wheeling stop: Selected
when free-wheeling stop is to be activated
(see under free-wheeling stop at the top of
this description) and reset (see description
of reset in parameters 400, 401), simulta-
neously.
Logic "0" will mean reset and free-wheel-
ing stop.
Stop: Selected if the frequency converter
is to be stopped (see description of stop in
parameters 400, 401). Logical "0" will
mean stop.
