Frequency bypass 4 (FREQ. BYPASS 4)
Value:
0.0 - parameter 200
0.0 Hz
Function:
Some systems call for some output frequencies to be
avoided because of resonance problems in the sys-
tem.
Description of choice:
Enter the frequencies to be avoided.
See also parameter 229.
234
Motor phase monitor
(MOTOR PHASE MON)
Value:
Enable (ENABLE)
[0]
Disable (DISABLE)
[1]
Function:
In this parameter it is possible to select monitoring of
the motor phases.
Description of choice:
If
Enable
is selected, the adjustable frequency drive will
react on a missing motor phase which will result in
alarm 30, 31 or 32.
If
Disable
is selected,
no
alarm is given if a motor phase
is missing. The motor can be damaged/overheated if
it runs on only two phases. It is therefore recommen-
ded to keep the missing motor phase function ENA-
BLED.
