Z
[100]
Function:
The jog frequency f
JOG
is the fixed output frequency at
which the FC motor is running when the jog function
is activated.
Description of choice:
Set the desired frequency.
214 Reference function (REF FUNCTION)
Settings:
★
Sum (SUM)
[0]
External/preset (EXTERNAL/PRESET)
[2]
Function:
It is possible to define how the preset references are
to be added to the other references. For this purpose,
Sum
is used. It is also possible - by using the
External/preset
function - to select whether a shift
between external references and preset references is
desired.
Description of choice:
If
Sum
[0] is selected, one of the adjusted preset
references (parameters 215-216) is added as a
percentage of the maximum possible reference.
If
External
/
preset
[2] is selected, it is possible to shift
between external references or preset references via
terminal 2, 3, 4, or 5 (parameter 332, 333, 334, or
335). Preset references will be a percentage value of
the reference range.
External reference is the sum of the analogue
references, pulses and bus references.

If
Sum
is selected, one of the preset
references will always be active. If the preset
references are to be without influence, they
should be set to 0 % (as in the factory setting).

0.00%
[0]
Function:
Two different preset references can be programmed in
parameters 215-216.
The preset reference is stated as a percentage of the
value Ref
MAX
or as a percentage of the other external
references, depending on the choice made in
parameter 214. If a Ref
MIN
≠
0 has been programmed,
the preset reference as a percentage will be
calculated on the basis of the difference between
Ref
MAX
and Ref
MIN
, following which the value is added
to Ref
MIN
.
Description of choice:
Set the fixed reference(s) that is/are to be the options.
To use the fixed references, it is necessary to have
selected Preset ref. enable on terminal 2, 3, 4, or 5
(parameters 332 - 335).
Choices between fixed references can be made by
activating terminal 2, 3, 4, or 5 - see the table below.

(CATCH UP/SLW DWN)
Settings:
0.00 - 100.00 %
[0 - 10000]
✭
0.00 %
[0]
Function:
This parameter enables the entry of a percentage
value (relative) which will either be added to or
deducted from the actual reference.
Description of choice:
If
Catch up
has been selected via one of the terminals
2, 3, 4, or 5 (parameters 332 - 335), the percentage
(relative) value selected in parameter 219 will be
added to the total reference.
