AC Induction (Asynchronous) Motor Setup
– With Encoder
Before you start
This section assumes that the encoder has been wired and configured correctly in the Encoder
Feedback section. And that moving the motor/encoder shaft by hand shows encoder counts in the
position window.

The AC Induction Motor Setup section is conceived for Motor#4, which is most commonly used
in Geo Brick Drive applications as a Spindle.

Caution
Using an external shunt resistor is highly advised with spindle
applications due to the excessive energy transmitted back into the Geo
Brick Drive during decelerations.

For simplicity and better presentation of the parameters to be set up, we will consider the following
example: A 4-axis Geo Brick Drive 8/16A, powered with 208VAC three-phase is driving a 230VAC
