Yaskawa V7N Drive with DeviceNet - Manual (Page 6)

Introduction
This document pertains to the V7N AC Drive. In this document, the word “Drive”, “AC Drive”, and
“inverter” may be used interchangeably. The V7N is a general purpose sine-coded pulse width
modulated AC motor Drive with embedded DeviceNet communications. It generates an adjustable
voltage/frequency three phase output for complete speed control of most conventional squirrel cage
induction motors. Automatic stall prevention and voltage boost prevent nuisance tripping during load
or line side transient conditions. The Drive will not induce any voltage line notching distortion back
to the utility line, and it maintains a displacement power factor of not less than 0.98 throughout its
speed range.
When properly installed, operated and maintained, the Drive will provide a lifetime of service. It is
mandatory that the person who operates, inspects, or maintains this equipment thoroughly read and
understand this manual before proceeding.
This installation guide details installation procedures and parameter setting ranges for the V7N
Drive. For programming and DeviceNet Communication protocol requirements, refer to the V7N
Drive with DeviceNet Technical Manual TM.V7N.01.
Receiving
Check nameplate - Be certain your input voltage source, motor and Drive nameplates are all
marked either 230V or 460V. Other voltages can be used, but require additional programming;
see TM.V7N.01.
