Requirements
To begin, make sure you have the following equipment:
- A small flat blade screwdriver for wiring and configuring the DIP switches (included).
- DC Power Source, 12-70VDC
- For more detailed information, please download and read the STM23R Hardware Manual, available at www.applied-motion.com/support/manuals
INSTALLATION
Step 1
Connect the drive to the DC power source. The STM23R will accept DC power
from 12-70VDC. 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)
Step 2
Connect input signals to the drive. STEP and DIR are required, EN and OUT are
optional.
- See the STM23R 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 7
Optional settings. The default settings for these switches are typically
sufficient. See the STM23R Hardware Manual for details on these functions.
- a) [Switch 5] Step Pulse Noise Filter
- b) [Switch 6] Step Smoothing Filter
- c) [Switch 8] Step Pulse Type (Step/Direction is default)
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.
