Pid Feedrate; Analog I/O - MERRICK Genetix Safety, Installation, Operation And Maintenance Manual

Load
In some cases the load signal generated by the feeder mechanics is unusable
to calculate feedrate as-is because of mechanically generated noise, for
example excessive ambient vibration. In these cases, a sliding average
algorithm calculates an average load with less noise. This parameter is settable
between 1 and 33 slots, with 1 representing no averaging. The result of the
averaging is used in feedrate calculations.
Note: The Speed signal can be further "damped" for display purposes only (see
Main Menu > Display Settings > Damping > Load).
Setpoint
In some cases the setpoint signal as received from the remote system is
unusable because it is too noisy. Therefore it also possible to average the
setpoint before it goes to the PID control algorithm. This is also a sliding
average, settable between 1 and 33 slots.

PID Feedrate

If, after Load averaging and Speed averaging, the calculated feedrate is still too
noisy, it can cause erratic control action as the PID algorithm tries to
compensate. Therefore it also possible to average the feedrate before it goes to
the PID control algorithm. This is also a sliding average, settable between 1 and
33 slots.
Note: It is very rarely necessary to set this parameter higher than 1 if Load
averaging and Speed averaging are used properly. Also, this is not the same as
the "actual" feedrate which can be damped for display purposes only (see Main
Menu > Display Settings > Damping > Feedrate).

Analog I/O

(Main Menu > Advanced Setup > Analog I/O)
This menu allows you to map the physical Analog Inputs and Analog Outputs to
specific logical functions, and to set certain properties for those IO. Physical inputs
are those that exist on the installed hardware. Physical inputs accept analog
information (such as current or voltage) from external sources, and physical outputs
present similar information. The exact number of physical Analog IO points and their
form depends on the installed hardware and the Configuration settings (see Main
Menu > Advanced Setup > Configuration).Selecting this menu item, you will be
presented with the following menu:
