Standard Integrated Microstepping Motor and Drive (Non-SCL)
Quick Start Guide
Step 1:
Do not apply power until all connections to the drive have been made.
Per the diagrams below, connect fused DC power to the V+ terminal on the STP-MTRD,
and DC Common to the V- terminal on the STP-MTRD. Note that the NEMA 23 V+ and Vconnector locations are the same as the NEMA 17 (pictured).
Requirements:
Each model accepts the following DC voltages:
• STP-MTRD-17x: 12-48 VDC
• STP-MTRD-23x: 12-70 VDC
If using an external fuse, the following slow blow fuses
are recommended:
• STP-MTRD-17x: 2 amp
• STP-MTRD-23x: 4 amp
Control wiring connections:
• STP-MTRD-17x: Includes a removable 11-pin
IDC connector with 12” leads. Long pre-made
control cables are available (STP-CLB-CAx)
• STP-MTRD-23x: Includes a removable 10-pin
field wireable connector (screw terminals).
Step 2:
Connect input signals to the drive. STEP and DIR are required, EN and OUT are optional.
See the User Manual for circuit connection details and examples (

STP-MTRD-17x: 11-pin connector. Color code is for 12” IDC cable (included w/motor) and optional
STP-CBL-CAxx cables.
STP-MTRD-23x: 10-pin screw terminal. Pinout is identical
to NEMA 17 version, except the “N.C.” is
not present.

Step 3:
In the “S/R” (Steps/Revolution) DIP switch
bank, select the desired step resolution (steps/
rev) using switches 1-4, located on the upper
block of four switches (pictured above).

Step 4:
In the “SETUP” DIP switch bank, set the motor’s
running current using switches 1 and 2. This is the
percentage of full current that the motor will use when
the shaft is rotating.

Step 8:
Optionally, you can test motor operation by activating
switch 4 in the “SETUP” DIP switch bank to initiate a self
test. The self test continually rotates the motor forward
and backward 2 1/2 revolutions.
Additional Help and Support
• For product support, specifications, pricing and installation troubleshooting, a Hardware User
Manual can be downloaded from the Online Documentation area of the AutomationDirect web
site.
• For additional technical support and questions, call our Technical Support team
@ 1-800-633-0405 or 770-844-4200.
Step 7:
Optional settings in the “SETUP” DIP
switch bank–the default settings for these
switches are typically sufficient. See the User
Manual for details on these functions.

Optional Encoder:
An optional encoder is available pre-mounted on “E” models. The standard encoder is a 1000ppr, Differential
line driver encoder. See below for pinouts and wire colors for the replacement cable (STP-CBL-EAxx) and
included cable with the STP-MTRD.
For more information on the encoder, please
see the Sure Step User Manual. Replacement
encoder part number is STP-MTRA-ENC1.

Step 5:
In the “SETUP” DIP switch bank, set the motor’s idle
current using switch 3. This is the percentage of running
current that the motor will use when the shaft is not
rotating. Choose 90% for maximum holding torque or
50% to reduce motor heating.
Step 6:
In the “SETUP” DIP switch bank, select the load-tomotor ratio category using switch 7. This is the ratio of the
effective load inertia to the motor’s own rotor inertia. For
high inertia loads choose 5-10X, and for low inertia loads
choose 0-4X. Setting the proper range for the load will
improve motor smoothness.
