4-56 Warning Feedback Low
Option: Function:
[-99999
9.999]
*
-999999.999 -
999999.999
Enter the lower feedback limit. When the feedback falls below
this 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.
4-57 Warning Feedback High
Range: Function:
999999.
999
*
[Par. 4-56 -
999999.999]
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 and
on relay output 01 or 02.
4-58 Missing Motor Phase Function
Option: Function:
[0] Off Displays an alarm in the event of a missing motor phase.
[1]
*
On No alarm displayed in the event of a missing motor phase. How-
ever, if the motor runs on only two phases, it can be damaged
by overheating. Retaining the
On setting is therefore strongly
recommended.
This parameter cannot be adjusted while the motor is running.
2.6.4. 4-6* Speed Bypass
Define the Speed Bypass areas for the ramps.
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]
0 RPM *
[0 - par. 4-13 RPM] Some systems call for avoiding certain output speeds due to
resonance problems in the system. Enter the lower limits of the
speeds to be avoided.
4-61 Bypass Speed From [Hz]
Array [4]
0 Hz *
[0 - par. 4-14 Hz] Some systems call for avoiding certain output speeds due to
resonance problems in the system. Enter the lower limits of the
speeds to be avoided.
