200 Rotation direction (ROTATION)
Settings:
✭
Only clockwise,
0-132 Hz (132 Hz CLOCK WISE)
[0]
Both directions,
0-132 Hz (132 Hz BOTH DIRECTIONS) [1]
Only counterclockwise, 0-132 Hz
(132Hz COUNTERCLOCKW.) [2]
Function:
This parameter guarantees protection against
unwanted reversing.
Using Process, closed loop mode (parameter 100)
parameter 200 must not be changed to Both
directions [1].
Description of choice:
Select the desired direction seen from the motor
drive end.
Note that if Only clockwise, 0-132 Hz [0]/ Only
counterclockwise, 0-132 Hz [2] is selected, the
output frequency will be limited to the range f
MIN
-
f
MAX
.
If Both directions, 0-132 Hz [1] is selected, the
output frequency will be limited to the range ± f
MAX
(the minimum frequency is of no significance).
NOTE!
This is only possible in Stop Mode (motor stopped on
a Stop command).
201 Min. output frequency

Function:
In this parameter, a minimum motor frequency limit
can be selected that corresponds to the minimum
frequency at which the motor is to run.

Parameter Group 2: References and Limits
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 Max. output frequency
(MAX OUTPUT FREQ)
Settings:
f
MIN
(parameter 201) - f
RANGE
(132 Hz, par. 200)
✭
f
RANGE
Function:
In this parameter, a maximum motor frequency can
be selected that corresponds to the highest
frequency at which the motor is to run.
See also parameter 205.
Description of choice:
A value from f
MIN
to 132 Hz can be selected.
203 Reference/feedback range
(REF/FEEDB. RANGE)
Settings:
★
Min - Max (MIN - MAX) [0]
- Max - + Max (-MAX-+MAX) [1]
Function:
This parameter decides whether the reference
signal is to be positive or can be both positive and
negative.
NOTE!
Analogue input (reference/feedback) can only be
positive.
Choose Min - Max [0] if Process, closed loop mode
has been selected in parameter 100.
