References and Limits 200-228
In this parameter group, the frequency and reference
range of the frequency converter are established. This
parameter group also includes:
-
Setting of ramp times
-
Choice of four preset references
-
Possibility of programming four bypass fre-
quencies.
-
Setting of maximum current to motor.
-
Setting of warning limits for current, frequen-
cy, reference and feedback.

50 Hz
Function:
In this parameter, a maximum output frequency can be
selected that corresponds to the highest speed at
which the motor can be.
NB!
The output frequency of the frequency
converter can never assume a value high-
er than 1/10 of the switching frequency
(parameter 407
Switching frequency
.
Description of choice:
A value from f
MIN
to the choice made in parameter 200
Output frequency
range can be selected.
