Minimum / maximum frequency Minimum / maximum frequency
Minimum / maximum frequency
Defines frequency limits of the frequency converter.
The default maximum value for parameters 1
.....
1 and 1
.....
2 is 120 Hz. By setting 1
. .
. . . 2 =
120 Hz when the device is stopped (RUN indicator not lit) parameters 1 ..... 1 and 1 ..... 2
are changed to 500 Hz. At the same time the panel reference resolution is changed
from 0.01 Hz to 0.1 Hz.
Changing the max. value from 500 Hz to 120 Hz is done by setting the parameter
1
.....
2 = 119 Hz when the device is stopped.

These limits correspond to the time required for the output frequency to
accelerate from the set minimum frequency (par. 1
