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 V-
connector 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.

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.
* Not present on NEMA 23 motors

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.
