Description
signal detection takes effect, if both the zero
position signal and running command signal are
detected, the operating lever zero position fault
STC is reported. If the running command is
given during zero position detection, the VFD
does not respond. If both the zero position
signal and running command signal still exist
after zero position detection, the operating lever
zero position fault STC is also reported. If the
zero position signal is removed suddenly during
zero position detection, the VFD does not
respond to the running command since zero
position detection is incomplete.

that AI2 is greater than 1.00V, the analog speed
reference deviation fault AdE is reported.
