Enter the upper
feedback limit. When the
feedback exceeds this
limit, the display reads
Feedb High. The signal
outputs can be
programmed to produce
a status signal on
terminal 27 or 29 (FC
302 only) and on relay
output 01 or 02 (FC 302
only).
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: Function:
[0] Disabled No alarm is displayed if
a missing motor phase
occurs.
[1] Trip 100 ms
[2] Trip 1000 ms
[3] Trip 100ms 3ph detec.
NOTE
This parameter cannot be adjusted while the motor is
running.
3.6.4 4-6* Speed Bypass
Some systems call for avoiding certain output frequencies
or speeds, due to resonance problems in the system. A
maximum of four frequency or speed ranges can be
avoided.
4-60 Bypass Speed From [RPM]
Array [4]
Range: Function:
Size related* [ 0 - par. 4-13
