SMD23E2 and SMD24E2 Connectors
Power and Inputs Connector
As shown in figure R1.4, the Power and Inputs Connector is located on the
back of the unit near its center. All digital input and power supply connec-
tions are made at this connector. The connector is a standard five pin A-
coded M12 connector that is rated to IP67 when the mate is properly
attached. Figure R1.5 shows the pinout of the connector when viewed
from the back of the unit.
Digital inputs are single ended and referenced to the DC Common pin.
(Sinking inputs.) Both inputs accept a nominal 5 Vdc to 24 Vdc signal
without the need of a current limiting resistor. Additional information on
how the digital inputs can be used can be found in the
section of the chapter, starting on page 17.
There are two power pins. DCPower
MAIN
powers both the control electron-
ics and the motor. DCPower
AUX
powers only the control electronics. Using
the DCPower
AUX
pin is optional. If your application requires you to cut
power to your motor under some conditions, using the DCPower
AUX
pin
allows you to cut power to your motor without losing your network con-
nection.
If the unit was ordered with an encoder, the DCPower
AUX
pin will also maintain power to the
encoder. If the motor shaft is rotated while motor power is removed, the encoder position will
update. Once power is restored to the motor, a Preset Position command can be issued to restore
the correct motor position without having to go through a homing sequence. If Stall Detection is
enabled on the SMD23E2/SMD24E2, it will also be able to tell the system if the motor shaft
rotated more than forty-five degrees with power removed.
Ethernet Connectors
Figure R1.4 shows the placement of the connectors on the SMD23E2 and SMD24E2 units. Figure R1.6
shows the pinout of the Ethernet connectors when viewed from the back of the unit. Each Ethernet port on the
SMD23E2/SMD24E2 is an “auto-sense” port that will automatically switch between 10baseT and 100baseT
depending on the network equipment it is attached to. Each port also has “auto switch” capability. This means
that a standard cable can be used when connecting the SMD23E2/SMD24E2 to any device, including a per-
sonal computer.

The connector is a standard four pin D-coded female M12 connector that is rated to IP67 when the mate is
properly installed.
