FIGURE 37. Pot wiring for Analog Command and Analog Feedback

Analog inputs 3 and 4 have different characteristics than inputs 1 and 2, and so require a lower resistance potentiometer in order to guarantee accuracy.

Important Notice

This wiring is also the one to use when the controller is in Analog mode but switched to RS232 after reset using the method discussed in “Entering RS232 from R/C or Analog mode” on page 105

Analog Feedback on Single Channel Controllers

On Single Channel controllers (SC Version - not to be confused with Dual Channel control- lers of which only one channel is used for position control - See “Single Channel Opera- tion” on page 177.), the controller accepts one command and uses one input for feedback.

Feedback Wiring in RC or RS232 Mode on Single Channel Controllers

When the controller is configured for RS232 or RC command, the wiring of the feedback must be done as shown in the figure below.
