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

139 Brake cut in frequency
(BRAKE CUT IN)
Settings:
0.5 - 132 Hz (parameter 200)
[5-]
✭
3.0 Hz
[30]
Function:
Here the frequency at which the external brake is to
be activated is selected via output set in parameter
340 when the motor is ramping down to stop.
Description of choice:
Set the desired frequency.

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).
NB!
This is only possible in Stop Mode (motor
stopped on a Stop command).

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.
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.
