G320X SERVO DRIVE
REV 10: May 13, 2010
Thank you for purchasing the G320X drive. The G320X DC servo drive is warranted to be free of manufacturing defects for 1 year
from the date of purchase. Any customer who is dissatisfied with it or is unable to make it work will be cheerfully refunded the
purchase price if the G320X is returned within 15 days of the purchase date.
PLEASE READ FIRST BEFORE USING THE G320X:
If you are not familiar with DC servo drives please do the following setup instructions with the motor on the bench before mounting it
on the mechanism it will eventually run. This will allow you to get a baseline motor behavior of what to expect.
Before you start, you must have a suitable encoder mounted and properly aligned on the motor. Follow the manufacturer’s
instructions on mounting and aligning the encoder if the motor doesn’t already come with one.
Next you must have a DC power supply suitable for the motor. The power supply current rating must equal the maximum current
you expect to run the motor at.
Finally, have a STEP and DIRECTION pulse source available.
Before going on, turn the “P”, “I”, “D”, and LIMIT trimpots to the 11 o’clock position. The trimpots are single-turn so be careful not to
over-torque them.
