Technical Note 

CTTN # 149    

 

This Technical Note is pertinent for Unidrive SP and Unidrive Classic 

 

Quick Setup/Checkout Guide 

 

There are many considerations when setting up a drive of which safety during 
commissioning is of primary concern.  One should always have a method of E-Stopping 
the drive and verify that it works before attempting a drive setup.  This guide is intended 
for the technician who is already familiar with the Unidrive Classic or Unidrive SP and is 
no substitute for the information provided in the User Guides for these products.  It is 
merely a short form guide outlining very basic initial setup steps toward the goal of 
verification of a drive and motor combination.
