F204
Secondary speed-
reference source
"Y”
Selection: 0: Internal reference (F155) – with memory
1: Analogue input AI1
2: Analogue input AI2
3: Pulse input OP1
4: Fix-frequencies, terminal control (digital inputs)
5: same as 1, (F155) but no memory
6: PID controller output
7: Potentiometer on keypad (AI3)
Default setting: 0
Secondary speed channel has the same function, as primary channel, if selected as the only reference. Setting parameter
F207,
both
channels, primary and secondary can be concatenated each other.
If
F204=0
, the value in
F155
works as initial speed reference, if secondary channel is used alone, in this case the value in
F156
is ignored
If
F207=1
or
F207=3:
value in
F155
and
F156
are valid for the secondary speed reference source
F205
and
F206
determine the range of the secondary speed channel, if analogue channel AI1 or AI2 are used for sec. speed ref. input
(F205=1 or 2)
If the potentiometer on the keypad panel is selected (F205=7), primary speed reference source is limited on fix-frequencies or MODBUS
setting
It is not allowed to configure primary and secondary speed reference source through the same channel
F205
Reference point for the range setting
of the secondary speed reference channel,
using AI1 or AI2
Selection: 0: referred on F-max
1: referred on the primary
speed channel “X”
Default setting: 0
F206
Range for secondary speed ref. „Y“ (%)
Range: 0….100 %
Default setting: 100
In case of combined speed control and secondary speed ref. input via
AI1
or
AI2
, parameter
F205
and
F206
determine the relation to the
primary reference
Combined speed control – between primary and secondary speed reference
F207
Output frequency as
combination between primary ("X)
and secondary ("Y") speed
reference signal
Selection:
0: X, only primary reference is used
1: X+Y Sum of primary and secondary reference
2: X or Y (terminal input selection)
3: X or X+Y (terminal input selection)
4: X (Fix-frequencies) and Y (analogue) combined
5: X-Y Difference between primary and secondary value
6: X+Y(F206-50%) * (value defined in F205)
Default setting: 0
If
F207=1:
X+Y, the sum of both channels is used – it is not allowed to use PID controller output for speed reference signals .
If
F207=3:
X or (X+Y) determine the output frequency, selection via terminal digital input. – is not allowed to use PID controller
output is not allowed for speed reference signal.
If
F207=4:
Fix-frequencies are the primary speed source, with priority to the analogue speed reference input for example
(F203=4 und F204=1).
If
F207=5:
The difference between both speed reference channels determine the output frequency – PID controller output is not
usable.
If
F207=6:
output frequency is set according to X+X(F206-50%)*F205 – PID controller output is not allowed
