During operation with the V/f characteristic
(P290 = 1) without encoder, it is necessary
for the correct function of the OFF1 command
that the P799 (OFF source set value) is set to
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
function diagram 480 are used, the actual source
value must be adjusted.
If P332 = 32000, the I-component is set to zero.
The individual frequency values have to be
in ascending order and must differ
from each other by at least 1 Hz.
