Analog Input
The STM23S/Q/IP drives feature an analog input (not available on STM23C drives). 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
STM23 drives provide a 5 volt DC, 50 mA output labeled +5V 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.
