200 Rotation direction
(ROTATION)
Value:
Only clockwise,
(ONLY CLOCKWISE)
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
If Both directions, 0-132 Hz [1] is selected, the output
frequency will be limited to the range ± f
minimum frequency is of no significance).
NB!:
This is only possible in Stop Mode (motor
stopped on a Stop command). Ramp will
be followed, if no set up change.
NB!:
If parameter 200, selection of direction, is set
for different values in the 2 setups, and the
setup is changed during operation, the direction
changes without ramping. In such cases trip may
occur and that may reduce the service life of the power
module, as well as it may be harmful to the application.
Therefore!
It is recommended not to set parameter 200 for
different values in the 2 setups. If that should be
necessary the user must make sure that setup
changes are only made with stopped motor.

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.

Function:
This parameter decides whether the reference signal is
to be positive or can be both positive and negative.
