4-58 Missing Motor Phase Function
Displays alarm 30, 31 or 32 in the event of a missing motor
phase. It is strongly recommended to enable to avoid motor
damage.
Option:

[1]
NOTE
This parameter cannot be adjusted while the motor is
running.

Function:
[ par. 4-54 - Enter the upper reference limit.
999999.999 ] When the actual reference
exceeds this limit, the display
reads Ref High. The signal
outputs can be programmed to
produce a status signal on
terminal 27 or 29 and on relay
output 01 or 02.
Function:
[ -999999.999 - Enter the lower
par. 4-57 feedback limit. When the
ReferenceFeed- feedback falls below this
backUnit] limit, the display reads
Feedb Low. The signal
outputs can be
programmed to produce
a status signal on
terminal 27 or 29 and
on relay output 01 or
02.
Function:
[ par. 4-56 - Enter the upper
999999.999 feedback limit. When
ReferenceFeed- the feedback exceeds
backUnit] this limit, the display
reads Feedb High. The
signal outputs can be
programmed to produce
a status signal on
terminal 27 or 29 and
on relay output 01 or
02.
Function:
Off No alarm is displayed if a
missing motor phase
occurs.
