3.5 C-## Frequency Control Functions
Parameter group related to the Jump Frequencies, Multi-step Frequencies, Job set-up, and Frequency Settings 2 and 3.
3.5.1 C-0# Frequency Control Functions
Parameters to configure Jump Frequencies 1, 2, 3, and 4, and Multi-step Frequencies 1 through 8.
C-01 Jump Frequency From [Hz]
Array [4]
Range: Function:
0 Hz* [0.0 - par. H-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.
C-02 Jump Speed From [RPM]
Array [4]
Range: Function:
0 RPM* [0 - par. H-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.
C-03 Jump Speed To [RPM]
Array [4]
Range: Function:
0 RPM* [0 - par. H-13 RPM] Some systems call for avoiding certain output speeds due to resonance problems in the system. Enter
the upper limits of the speeds to be avoided.
C-04 Jump Frequency To [Hz]
Array [4]
Range: Function:
0 Hz* [0.0 - par. H-14 Hz] Some systems call for avoiding certain output speeds due to resonance problems in the system. Enter
the upper limits of the speeds to be avoided.
C-05 Multi-step Frequency 1 - 8
Array [8]
Range: 0-7
Range: Function:
0.00 %* [-100.00 - 100.00 %] Enter up to eight different preset references (0-7) in this parameter, using array programming. The preset
reference is stated as a percentage of the value Ref
MAX
(par. F-53 Maximum Reference) If a Ref
MIN
different
from 0 (par. F-52 Minimum Reference) is programmed, the preset reference is calculated as a percentage
of the full reference range, i.e. on the basis of the difference between Ref
MAX
and Ref
MIN
. Afterwards, the
value is added to Ref
MIN
. When using preset references, select Preset ref. bit 0 / 1 / 2 [16], [17] or [18] for
the corresponding digital inputs in parameter group E-##.
