The unit differentiates between two setpoint adjustments:
ï the setpoint adjustment in percent
With the adjusted setpoint limits the speed range 0%...100% is defined. In
this case the adjustment 0% corresponds to the minimal speed and 100%
to the maximal speed. The speed after the setpoint limiting is calculated
according to following formula:
positive setpoint = oP.6 + (setpoint adjustment [%] x
negative setpoint = oP.7 + (setpoint adjustment [%] x
ï the absolute setpoint adjustment, i.e. the setpoint is directly adjusted as
speed and limited through the corresponding minimal and maximal values
as well as through the absolute maximal value.
The setpoint sources are assigned as follows:
Setpoint adjustment in percent
Terminal strip (analog setpoint)
Keyboard/Bus in %
Motorpoti
