Conveyor systems, pumps etc. are often operated at a
basic speed which can be increased as required.
Here, the speed is implemented by the 8200 motec by
preselection of a main setpoint and an additional
setpoint. These setpoints may originate from different
sources (e.g. PLC and setpoint potentiometer).
The 8200 motec adds the two analog setpoints and then
increases the speed of the motor accordingly.
The upward and downward ramps for both setpoints
are variable and can be adjusted to ensure smooth
acceleration. The main setpoint ramp can also be set as an
S-ramp.
