PI feedback controller connection to production equipment
The connection of the PI feedback controller depends on the configuration of the insulation extruder
or capstan drive control inputs.
Connection 1
In this configuration, the PI feedback controller output voltage is added in series with a fixed control
voltage from a potentiometer or PLC. The fixed control voltage sets the capstan or extruder operating
midpoint and the PI feedback controller output drives the capstan or extruder above or below this
operating midpoint.
Note that the PI feedback controller ground reference (0V) is not connected to the 0V reference of the
controlled equipment; this is possible as the PI feedback controller ground reference is isolated from
earth.
Connection 2
In this configuration, the PI feedback controller output voltage is added to a fixed control voltage from
a potentiometer or PLC via the auxiliary control input on the extruder or capstan driver. The fixed
