200 Output frequency range/direction
(OUT FREQ RNG/ROT)
Value:
Only clockwise, 0-132 Hz
(132 Hz CLOCK WISE)
[0]
Both directions, 0-132 Hz
(132 Hz BOTH DIRECT.)
[1]
Only clockwise, 0-1000 Hz
(1000 Hz CLOCK WISE)
[2]
Both directions, 0-1000 Hz
(1000 Hz BOTH DIRECT.)
[3]
Only counter clockwise, 0-132 Hz
(132 Hz COUNTERCLOCK)
[4]
Only counter clockwise, 0-1000 Hz
(1000 Hz COUNTERCLOCK)
[5]
Function:
This parameter guarantees protection against unwan-
ted reversing. Furthermore, the maximum output fre-
quency can be selected that is to apply, regardless of
the settings of other parameters.
NOTE
The output frequency of the adjustable
frequency drive can never assume a value
higher than 1/10 of the switching frequen-
cy, see parameter 411.
Is not to be used together with Process control, closed
loop (parameter 100) .
Description of choice:
Select the desired direction as well as output frequen-
cy.
Note that if Clockwise, 0-132 Hz [0], Clockwise, 0-1000
Hz [2], Counter clockwise, 0-132 Hz [4] or Counter
clockwise, 0-1000 Hz
[5] is selected, the output fre-
quency will be limited to the range f
MIN
- f
MAX
.
If Both directions, 0-132 Hz [1] or Both directions,
0-1000 Hz [3] is selected, the output frequency will be
limited to the range ± f
MAX
(the minimum frequency is
of no significance).
Example:
Parameter 200 Output frequency range/direction =
both directions .
201 Output frequency low limit (F
MIN
)
(OUT FREQ LOW LIM)
Value:
0.0 - f
MAX
0.0 Hz
Function:
In this parameter, a minimum motor frequency limit
can be selected that corresponds to the minimum fre-
quency at which the motor is to run.
The minimum frequency can never be higher than the
maximum frequency, f
MAX
.
If
Both directions
has been selected in parameter 200,
the minimum frequency is of no significance.
Description of choice:
A value from 0.0 Hz to the max. frequency selected in
parameter 202 (f
MAX
) can be chosen.
202 Output frequency high limit (FMAX)
(OUT FREQ HI LIM)
Value:
f
MIN
- 132/1000 Hz (parameter
200) depends on unit
Function:
In this parameter, a maximum motor frequency can be
selected that corresponds to the highest frequency at
which the motor is to run. The factory setting is 132 Hz
