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
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. F-17
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. F-17
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 - par. F-15
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 % * [-100 -
100 %]
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
(F-53 Maximum Reference) If a Ref MIN different
C-05 Multi-step Frequency 1 - 8
Array [8]
Range: 0-7
Range: Function:
from 0 (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-##.
Illustration 3.18 Preset Reference
Preset ref. bit 2 1 0
Preset ref. 0 0 0 0
Preset ref. 1 0 0 1
Preset ref. 2 0 1 0
Preset ref. 3 0 1 1
Preset ref. 4 1 0 0
Preset ref. 5 1 0 1
Preset ref. 6 1 1 0
Preset ref. 7 1 1 1

3.5.2 C-2# Jog Set-Up
Parameters to configure Jog Speed, Jog Accel/Decel Time
and Quick Stop Decel Time.
C-20 Jog Speed [Hz]
Range: Function:
0 Hz * [0 - par. F-15
Hz]
The jog speed is a fixed output speed at
which the frequency converter is running
when the jog function is activated.
See also C-22 Jog Accel/Decel Time.
