Feedrate SP

If you select this parameter, the analog input received will be mapped to a
value representing the desired feedrate (i.e. the Feedrate setpoint). This will
be used to control the feeder if the Feeder Control Method is "Rate Control"
(see Main Menu > Advanced Setup > Feeder Control > Method), and the
Feeder Control Source is "Remote Analog" (see Main Menu > Advanced
Setup > Feeder Control > Source ). The data will be scaled according to the
Calibration of this analog input and the parameters under Numeric Data (see
below).

Speed SP

If you select this parameter, the analog input received will be mapped to a
value representing the desired belt speed (i.e. the Speed setpoint). This will
be used to control the feeder if the Feeder Control Method is "Speed
Control" (see Main Menu > Advanced Setup > Feeder Control > Method),
and the Feeder Control Source is "Remote Analog" (see Main Menu >
Advanced Setup > Feeder Control > Source ). The data will be scaled
according to the Calibration of this analog input and the parameters under
Numeric Data (see below).

Oloop SP

If you select this parameter, the analog input received will be mapped
directly to the Belt Speed Demand output, bypassing all closed loop control.
This will be used to control the feeder if the Feeder Control Method is "Open
Loop" (see Main Menu > Advanced Setup > Feeder Control > Method), and
the Feeder Control Source is "Remote Analog" (see Main Menu > Advanced
Setup > Feeder Control > Source ). The data will be scaled according to the
Calibration of this analog input and the parameters under Numeric Data (see
below).
Load
If you select this parameter, the analog input received will be mapped to a
value representing the actual belt load. This might be useful if the belt load is
being measured by a sensor that transmits an analog output. The data will
be scaled according to the Calibration of this analog input and the
parameters under Numeric Data (see below).
Speed
If you select this parameter, the analog input received will be mapped to a
value representing the actual belt speed. This might be useful if the belt
speed is being measured by a sensor that transmits an analog output. The
data will be scaled according to the Calibration of this analog input and the
parameters under Numeric Data (see below).
Inclination
If you select this parameter, the analog input received will be mapped to a
value representing the angle of the feeder or conveyor. This value then is
used to correct the measured load according to the angle. This might be
useful if the scale or feeder is mounted in such a way that the angle relative
to earth is changeable, allowing automatic correction. The data will be scaled
