signal received
Drive has received
emergency stop
command and ramps
to stop according to

parameter 2208
EMERG DEC TIME.
Motor identification
magnetization is on.
This alarm belongs to
normal start-up
procedure.
Intermediate circuit DC
voltage is oscillating
due to missing input
power line phase or
blown fuse.
Alarm is generated
when DC voltage
ripple exceeds 14% of
nominal DC voltage.
Condition defined by
3701 USER LOAD C
MODE has been valid
longer than half of the
time set by 3703
