200 Output frequency range
(OUT FREQ. RNG/ROT)
Value:
Only clockwise, 0 - 132 Hz
(132 HZ CLOCKWISE)
Both directions, 0 - 132 Hz
(132 HZ BOTH DIRECT)
Anti-clockwise only, 0 - 132 Hz
(132 HZ COUNTER CLOCK)
Clockwise only, 0 - 1000 Hz
(1000 HZ CLOCK WISE)
Both directions, 0 - 1000 Hz
(1000 HZ BOTH DIRECT)
Counter-clockwise only, 0 - 1000 Hz
(1000 HZ COUNTER CLOCK)
Function:
This parameter guarantees protection against
unwanted reverse. Furthermore, the maximum output
frequency can be selected that is to apply regardless
of the settings of other parameters. This parameter
has no function if Process regulation, closed loop has
been selected in parameter 100 Configuration.
Description of choice:
Select the required direction of rotation as well as
the maximum output frequency. Please note that if
Clockwise only [0]/[3] or Counter-clockwise only [2]/[5]
is selected, the output frequency will be limited to the
range f -f . If Both directions [1]/[4] is selected,
MIN MAX
the output frequency will be limited to the range ± f
(the minimum frequency is of no significance).

201 Output frequency low limit, f
(MIN OUTPUT FREQ)
Value:
0.0 - f
MAX
Function:
In this parameter, a minimum motor frequency limit can
[0]
be selected that corresponds to the minimum speed
at which the motor is allowed to run. If Both directions
[1]
has been selected in parameter 200 Output frequency
range, the minimum frequency is of no significance.

Description of choice:
[3]
The value chosen can range from 0.0 Hz to
the frequency set in parameter 202 Output

frequency high limit, f
[5]
202 Output frequency high limit, f
(MAX. OUTPUT FREQ)
Value:
f - 132/1000 Hz (par. 200 Output frequency range)
MIN
Function:
In this parameter, a maximum output frequency limit
can be selected that corresponds to the highest
speed at which the motor is allowed to run.
NOTE
The output frequency of the variable
frequency drive can never assume a value
higher than 1/10 of the switching frequency
MAX
(parameter 411 Switching frequency).
Description of choice:
A value can be selected from f
in parameter 200 Output frequency range.
