Starting Up the Drive for Volts/Hertz Regulation
CHAPTER 1
Starting Up the Drive
for Volts/Hertz Regulation
This chapter describes the basic start-up procedure for drives which utilize open-loop
V/Hz regulation. V/Hz regulation is the default method of regulation. You do not
need to select it.
If you are starting up a drive which will perform vector regulation, refer to the vector
start-up procedure in chapter 2.0 instead. Do not perform the start-up procedure in
this chapter.
The start-up procedure below provides step-by-step instructions for:
• powering up
• checking monitor mode displays
• accessing program mode
• configuring General parameters (designated with a "P")
• configuring specific V/Hz parameters (designated with an "H")
• checking motor rotation direction
• running the drive
This start-up procedure describes how to program the minimum set of parameters
that usually need to be programmed for applications using V/Hz regulation. Once
you program these parameters, their values are retained even if power is lost. You
only need to re-program them if you want to change how the drive operates.
Your application may require programming other parameters in addition to the ones
described in this start-up procedure. Refer to chapter 4 for a description of all the
parameters to verify whether you need to program any additional parameters as
well. Appendix A provides a list of parameters listed alphabetically.
Throughout this manual, you will see references to parameter names and the
numbers that identify them for the drive. This manual uses the same format that will
be shown on the keypad/display to refer to parameters:
P.nnn
U.nnn
H.nnn
r.nnn
where: nnn is a number
P designates General parameters
U designates Vector parameters
H designates Volts/Hertz parameters
r designates optional RMI parameters
