FC 300 Design Guide
How to Program
- The choice of configuration in par. 1-00
Configuration Mode:forSpeed closed-loop
[1], RPM ; for Torque [2], Nm.
- The unit selected in par. 3-01 Refer-
ence/Feedback Unit.
3-04 Reference Function
Option:
*
Sum [0]
External/Preset [1]
Function:
Select Sum [0] to sum both external and
preset reference sources.
Select External/Preset [1] to use either the preset
or the external reference source.
" 3-1* Refere nces
Parameters for se tting up the reference sources.
Select the preset reference(s). Select Preset ref. bit
0/1/2[16], [17] or [18] for the corresponding
digital inputs in p arameter group 5.1* Digital Inputs.
3-10 Preset Referen ce
Array [8]
Range:
-100.00 - 100.00%
*
0.00%
Function:
Enter up to eight different preset references (0-7)
in this parameter, using array programming. The
preset re ferenc e is state d as a percentage of the
value Ref
MAX
(par. 3-03 Maximum Reference)or
as a percentage of the other external references.
If a Ref
MIN
0 (Par. 3-02 Minimum Reference)is
programmed, the p reset 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 5.1* Digital Inputs.
3-11 Jog Speed [Hz]
Range:
0.0 - par. 4-14 Hz
*
5Hz
Function:
The jog speed is a fixed output speed at which
the adjustable frequency drive is running when
the jog function is activated.
See also par. 3-80.
3-12 Catch-up/slow-down value
Range:
0.00 - 100.00%
*
0.00%
Function:
Enter a percentage (relative) value to be either
added to or deducted from the actual reference for
catch-up or slow-down respectively. If Catch-up
is selected via one of the digital inputs (par. 5-10
to par. 5-15), the percentage (relative) valu
eis
added to the total r efere n ce. If Slow-down is
selected via one of the digital inputs (par. 5-10
to par. 5-15), the pe rcentage (relative) va
lue
is deducted from the total reference. Obtain
extended functionality with the DigiPot function.
See parameter group 3-9* Digital Pot
entiometer.
3-13 Reference Site
Option:
*
Linked to Hand / Auto [0]
Remote [1]
Local [2]
Function:
Select which reference site to
activate.
*
default setting ()display text []value for use in communication via serial communication port
