Applied Motion STM17C-3CE - Manual (Page 21)

The Analog (AIN) Input
The STM17 drives feature an analog input. The input can accept a signal
range of 0 to 5 VDC. The drive can be configured to operate at a speed or
position that is proportional to the analog signal. Use the ST Configurator
software to set the signal range, offset, dead-band and filter frequency. The
STM17 drives also provide a +5VDC 100ma output that can be used to
power external devices such as potentiometers. It is not the most accurate
supply for reference; for more precise readings use an external supply that can provide the desired accuracy.
