Yaskawa F7 Drive 1500 Hz Output - Manual (Page 2)

Date: 05/05/05, Rev: 05-05 Page 2 of 7 TM.F7SW.056
This document is intended to provide proper installation and use of the Yaskawa drive with custom software. This
document is a supplement to the standard drive technical manual. It describes the effects on the drive parameters
and functions with the software installed. Read and understand this document and the standard drive technical
manuals before attempting to install, adjust, operate, inspect or maintain the drive. Observe all cautions and
warnings in this document and the standard drive technical manuals. Custom software is written to add
functionality to a standard AC drive to enhance or enable use in a specific application. The software is loaded to
the flash ROM area of the control board, and replaces the standard drive software. Custom software can add new
functions, modify standard functions, or even inhibit standard functions. It can be used to modify display text or
parameter names. Custom software is usually loaded to the drive before delivery. The control board and drive
nameplate are assigned unique part numbers and the software is registered, archived, and retrievable.
When seeking support for a drive with custom software, it is imperative to provide the unique part number shown
on the drive nameplate. The software has been flashed to the control board memory and the operation of
parameters, functions, and monitors are different than the standard drive software, as described herein.
1.0 Overview
This custom software is designed for high frequency motor (spindle) applications. The drive’s maximum output
frequency can be set to either 1000Hz or 1500Hz, depending upon C6-11. C6-11 is a factory level parameter
that can be accessed by setting A1-04 = 0616 (Password) and then setting A1-01 = 616 (Access Level). Do not
change any other factory parameters. Non-applicable drive functions have been deleted in order to optimize
CPU processing time for this software.
