Stepper Motor Wiring
Revision E
In an effort to constantly improve our products, AMCI has replaced older versions of our stepper motors
with new, more powerful motors. Some of these newer motors had different current requirements,
wiring, and shaft sizes than their older counterparts.
The following tables list all of the Stepper Motors ever carried by AMCI and show the current
requirements and the motor’s shaft size.
Wiring Information
When operating, the case of a stepper motor may reach 100°C.
Because there are several versions of the SM23 stepper motors that used the same part numbers,
please use the wire colors and cable length to determine exactly which version of the stepper motor
that you have.
The “xy” in the motor part number can blank for a single shaft motor, “D” for a double shaft motor,
or “DE” for a double shaft motor with a 1000 line incremental encoder.
All of the wiring connections shown are for the SD17063, SD17040, SD17040C, SD17060,
SD17060B, SD17060E, SD17080, SD31045, or the SD31045E stepper drivers.
On all of these drivers, it is also necessary to have a wire connecting the two INTERLOCK terminals
at the top and bottom of the motor connector. The driver will indicate a FAULT condition if this wire
is not present.
For the drivers short circuit protection to operate correctly, you must also connect a drain wire from
the case of the motor to the Earth Ground terminal of the driver.
Even though it is possible to extend the cable length up to forty feet, AMCI recommends installing
the driver as close as possible to the motor. This will decrease the chance of forming a ground loop
and has the added benefit of limiting the amount of power loss in the motor cable. If you must extend
the cable, you should use a cable with twisted pairs 18AWG or larger and an overall shield. The
Beldin 9552 (four wire) and the Beldin 9554 (six wire) meet this requirement.
The SD8055 and SD3520 stepper drivers do not have Ctap terminals. When connecting a series
wired motor to these drivers, it will be necessary to use a wire nut to hold the motor’s leads together.
In addition, for CW increasing readings, looking at the flange of the motor, it will be necessary to
reverse the wiring to the B- and B+ terminals. Operate motors below 100 C.
The following tables show the wiring of the four lead SM2340-130 and SM2340-240 stepper motors.
