200 Rotation direction (ROTATION)
Settings:
Only clockwise,
0-132 Hz (132 Hz CLOCK WISE)
Both directions,
0-132 Hz (132 Hz BOTH DIRECTIONS)
Only counterclockwise, 0-132 Hz
(132Hz COUNTERCLOCKW.)
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
f .
MAX
If Both directions, 0-132 Hz [1] is selected, the
output frequency will be limited to the range ± f
(the minimum frequency is of no significance).
NOTE!
This is only possible in Stop Mode (motor stopped on
a Stop command).

H
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.

FCM 300 Series
The minimum frequency can never be higher than
the maximum frequency, f
[0]
If Both directions has been selected in parameter
200, the minimum frequency is of no significance.

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.

203 Reference/feedback range
(REF/FEEDB. RANGE)
Settings:
Min - Max (MIN - MAX)
- Max - + Max (-MAX-+MAX)
Function:
This parameter decides whether the reference
signal is to be positive or can be both positive and
negative.

NOTE!
[60]
Analogue input (reference/feedback) can only be
positive.
Choose Min - Max [0] if Process, closed loop mode
has been selected in parameter 100.
