Analog Feedback on Single Channel Controllers

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.

Feedback Wiring in Analog Mode on Single Channel Controllers

When the controller is configured in Analog mode, the analog input 1 is used for com- mands while the analog input 4 is used for feedback. Note that the analog inputs 3 and 4 are only available on the AX2550 with PCB revision 6.1 or above. The PCB revision can be found on the sticker affixed at the bottom of the case. Roborun will detect the new hard- ware revision and display Rev B on the screen.

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.
