Analog inputs
The command and position analog inputs are used when the steer command and
position feedback devices are pots or sine/cosine sensors or sawtooth sensors.
The motor temperature sensor input provides a constant current appro
-
priate for a thermistor sensor. Some standard predefined motor temperature
sensors are supported in software (see Sensor Type parameter, page 49). Note:
The industry standard KTY temperature sensors are silicon temperature sensors
with a polarity band; the polarity band of a KTY sensor must be the end
connected to I/O Ground (pin 7).
All analog inputs are protected against shorts to B+ or B-.

Power supply outputs
The +5V supply is used for all steer command and position feedback devices.
The +10V supply is provided for the handheld programmer; it should not be
used for steer command or position feedback devices because voltage could
change when the programmer is plugged in. Both power supply outputs are
protected against shorts to B+ or B-.
