I/O Connections Example (D-Style Motors)
Encoders, ports, switches and buttons can be connected directly to the SmartMotor's I/O pins.
The following figure provides an example of some common I/O connections to the D-style
SmartMotor's 15-pin D-sub connector.

Common I/O Signals and Connections
NOTE:
Class 5 D-style SmartMotor I/O is Sinking type (NPN); Class 5 D-style AD1,
Class 5 M-style and Class 6 SmartMotor I/O are Sourcing type (PNP).
For additional connector, pinout and cabling information, refer to the
SmartMotor Installation
& Startup Guide
for your motor.
I/O Voltage Spikes
This section provides information on how the SmartMotor handles voltage spikes on the I/O
lines.
While all SmartMotor I/O is confined to operate between 0 and 5 VDC, some circuitry exists to
accommodate spikes above and below the operational range. This is permitted as long as
those spikes are moderate and have a short duration.
Refer to the following figure. Notice from the schematic that an I/O point can be configured as
an output. However, it can still be readable as an analog input because the connections to the
CPU are separate.
