About this Manual 
IMPORTANT  Motors used must be suitable for Inverter duty. 
Note  Do not attempt to control motors whose rated current is less than 25% of the drive rated current. Poor 
motor control or Autotune problems may occur if you do. 
This manual is intended for use by the installer, user and programmer of the 890 drive. It assumes a 
reasonable level of understanding in these three disciplines. 
Note  Please read all Safety information before proceeding with the installation and operation of this unit. 
It is important that you pass this manual on to any new user of this unit. 
How the Manual is Organised 
This Engineering Reference manual is organised into chapters, indicated by the numbering on the edge of 
each page. 
Information for all 890 units is included (890CS Common Bus Supply, 890CD Common Bus Drive, 890SD 
Standalone Drive). 
The manual is more detailed than the relevant QuickStart manual, and so is of use to the unfamiliar as well 
as the high-end user.
