<1> The individual frequency values have to be
in ascending order and must differ
from each other by at least 1 Hz.
<2> If P332 = 32000, the I-component is set to zero.
During operation with the V/f characteristic
(P290 = 1) without encoder, it is necessary
f
for the correct function of the OFF1 command

that the P799 (OFF source set value) is set to
P326, P328
200. In order to avoid the alarm
"Set-Actual Deviation", the P791 (source
variable) should also be set to 200.

In case further "messages" from the
