CONNECTING YOUR MOTOR
Compatible Motors
The SD17040C will work with many different motors, including those not sold by AMCI. This section
assumes that you have already chosen your motor and you are looking for wiring information. No wire colors
are given because there is no single industry wide color coding standard for stepper motor wires. You must
refer back to your motor data sheets for this information.
AMCI offers several different stepper motors in sizes 23, 34, and 42. Refer to our website, www.amci.com,
for additional information on these products.
Motor Wiring
The Interlock jumper is a safety
device that is needed for proper
operation. The SD17040C will not
power the motor without this jumper.
When the jumper is installed,
up to 170Vdc is present on the
connector. Do not use the Interlock
for anything other than its
intended use as a safety device.

NOTES
1)
170Vdc is present on the
connector when power is applied
to the motor. Install the supplied
rubber boot on the connector
during normal operation.
2)
Motor connections should be tight.
Loose connections may lead to
arcing which will heat the connector.
Phoenix Contact specifies a tighten-
ing torque of 4.4 to 5.4 lb-in. (0.5 to
0.6 Nm)
3)
Refer to the torque vs. speed curves on your motor's
specifications sheet to determine if you should wire the
motor to the SD17040C in series, parallel, or centertap
configuration.
