5.3 Trimmer
All of the trimmers required for the adjustment of the drive regulator to the respective
application are located on the unit boards. All of the trimmers are pre-set to the standard
parameters and/or the customer commissions so that the customer normally does not have
to re-adjust the trimmers.
Adjustment right = value increases
Adjustment left = value decreases
OFFSET Speed offset balancing
Put set point input to "0“.
Enable drive control,
i.e. set ENABLE to HIGH potential.
Set motor at standstill with "OFFSET“ trimmer.
