STM17R Quick Setup Guide
STM
Requirements
To begin, make sure you have the following equipment:
▪ A small at blade screwdriver for conguring the DIP switches (included).
▪ DC Power Source, 12-48VDC
▪ For more detailed information, please download and read the STM17R Hardware Manual, available at www.applied-motion.com/support/manuals.
Step 1
Connect the drive to the DC power source. The STM17R will accept DC
power from 12-48VDC.
Per the diagram at the right, connect the red wire to the positive output
terminal on the power supply, typically marked V+, and the black wire to
the negative terminal, typically marked V-.
(Do not apply power until all connections to the drive have been made)

Connect input signals to the drive. STEP and
DIR are required, EN and OUT are optional.
▪ See the STM17R Hardware Manual for circuit
connection details and examples.
Step 3
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 4
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 5
Select the load-to-motor inertia 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.
Step 6
Select the desired step resolution (steps/rev) using switches 1-4, located on a
second block of 4 switches.

Step 8
Optionally, you can test motor operation by activating switch 4 to initiate a
self test move.
▪ The self test move continually rotates the motor forward and backward
2-1/2 revolutions.
