Connecting the Motor
Motor Connector
The motor connector is shown in figure 4.2. The two Interlock termi-
nals are a safety feature. When these two terminals are not connected,
the drive will not power the motor outputs, and the drive blinks the Sta-
tus LED red and activates the Fault Output. For normal operation, these
two terminals must be connected together with a short wire.
The Interlock terminals are meant as a safety feature, not
an alternate way to disable the motor. Use only a short
jumper to connect these pins and do not run this connec-
tion through relay contacts.
The two center tap pins, A CTAP and B CATP, are there for wiring
convenience only. They are electrically isolated from the rest of the
drive and are not used to power the motor. The
EARTH GND
pin is for
the shields of the motor cable. This pin is directly connected to the
grounding lug of the SD17060E.
When powered, the motor connector represents a shock hazard because it has 170 Vdc present
on its terminals. A rubber boot that is included with the connector must be installed but is not
shown in the following figures for clarity. When installing the motor cable, slide the rubber
boot onto the cable before wiring the connector. When you’re sure the wiring is correct, slide
the boot over the connector to cover the screw heads.
Always remove power from the SD17060E before connecting or disconnecting the
motor.
1) Never connect the motor leads to ground or to a power supply.
2) Always connect the cable shield to the Earth Ground terminal of the SD17060E’s Motor
Connector.
3) Never use the Interlock Connection to disable the motor. A short wire within the connector
boot must be used.
Motor Wiring
The SD17060E 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 in the figures below because there is no single industry wide color coding scheme for stepper
motors. You must refer to your motor data sheets for this information.
A wiring document for all of the motors ever sold by AMCI is available on our website. This single docu-
ment contains all of the information necessary to connect any AMCI motor to any AMCI drive. At the time of
this manual revision, the wiring manual can be found in the PDF Documents section of the website. It is
under the Stepper Motor heading, and link is simply called “wiring”.
The figure on the following page shows how to wire a motor to the SD17060E in series, parallel, or center-tap
configurations.
