Analog Connections Overview
The analog connection block consists of two channels. Each channel has a signal pin and a + and – pin for powering
the analog voltage source. These potentiometer power pins are special in that they allow the Simple Motor Controller
to detect if an analog channel has become disconnected, so we recommend using these pins rather than alternate
power supplies or other pins on the board.
If you use an analog voltage source that is not powered from the Simple Motor Controller’s
potentiometer power (+ and –) pins, you will need to check the Ignore Pot Disconnect checkbox under
the Advanced Settings tab of the Simple Motor Control Center (see
Section 5.3 ).
We recommend using a potentiometer in the 1 kΩ to 10 kΩ range. Higher-resistance potentiometers will not work
well with the potentiometer disconnection detection feature. If you need to use a higher-resistance potentiometer, you
can disable potentiometer disconnection detection from the Simple Motor Control Center.
