VFD brake
failure output
Zero servo is used in closed-loop vector control to
check whether the pulse count at stop is greater
than the threshold P93.05. If the threshold is
exceeded, a brake failure alarm is reported. The
output can be set through relay. After the time
P93.06 (if the pulse count is greater than triple of
P93.05, the delay P93.06 is directly skipped), if the
option " Zero servo input slows down" is selected,
the VFD runs downward slowly at the frequency
P93.03 and coasts to stop within the time P93.04.
Then the VFD performs inspection again.
(2) When P93.02=2: Zero servo input is always
valid (keeping running at zero speed).
