Verify Motor Encoder
Resolution This test compares the physically measured distance to the distance calculated by
the software. It also verifies the encoder setting in the RSLogix 5000 software.
1. Measure and mark a fixed distance of travel on the axis.
2. Record the ActualPosition tag value with carriage at the starting position.
3. Move the carriage to the end position.
4. Record the ActualPosition tag value.
5. Calculate the distance moved by using the record values.
6. Compare the actual distance and the calculated distance.
If the values do not match, verify the resolution of the installed encoder
and the values used in the Motor Feedback, Conversion, and Units tabs.
Verify Linear Motor Wiring
and Function In RSLogix 5000 software, click the Homing and Hookup tabs to check that the
motor power, Hall sensing, and the encoder signal wiring is correct.
Follow these steps to verify your motor wiring and function.
1. Click the Hookup tab.
2. Configure the parameters.
The following table shows the suggested settings.
IMPORTANT The following components must be wired correctly for your drive and
linear motor to operate properly:
• Hall effect module
• Coil power wires
• Thermistor or thermal switch
• Encoder
