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 - par. F-15 Some systems call for avoiding certain
*
Hz] 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. F-17 Some systems call for avoiding certain
*
RPM] 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. F-17 Some systems call for avoiding certain
*
RPM] 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 - par. F-15 Some systems call for avoiding certain
*
Hz] 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 % [-100 - Enter up to eight different preset references
