Warnings and Cautions
This Section provides warnings and cautions pertinent to this product, that if
not heeded, may result in personal injury, fatality, or equipment damage.
Yaskawa is not responsible for consequences of ignoring these instructions.
WARNING
YASKAWA manufactures component parts that can be used in a wide variety of industrial applications. The selection and application of
YASKAWA products remains the responsibility of the equipment designer or end user. YASKAWA accepts no responsibility for the way its
products are incorporated into the final system design. Under no circumstances should any YASKAWA product be incorporated into any product
or design as the exclusive or sole safety control. Without exception, all controls should be designed to detect faults dynamically and to fail safely
under all circumstances. All products designed to incorporate a component part manufactured by YASKAWA must be supplied to the end user
with appropriate warnings and instructions as to that part’s safe use and operation. Any warnings provided by YASKAWA must be promptly
provided to the end user. YASKAWA offers an express warranty only as to the quality of its products in conforming to standards and
specifications published in the YASKAWA manual. NO OTHER WARRANTY, EXPRESS OR IMPLIED, IS OFFERED. YASKAWA assumes

Read and understand this manual before installing, operating, or servicing this drive. All warnings, cautions, and instructions must be
followed. All activity must be performed by qualified personnel. The drive must be installed according to this manual and local codes.
Do not connect or disconnect wiring while the power is on. Do not remove covers or touch circuit boards while the power is on. Do not
remove or insert the digital operator while power is on.
Before servicing, disconnect all power to the equipment. The internal capacitor remains charged even after the power supply is turned off.
Status indicator LEDs and Digital Operator display will be extinguished when the DC bus voltage is below 50 VDC. To prevent electric
shock, wait at least 5 minutes after all indicators are OFF and measure DC bus voltage and verify that it is at a safe level.
Do not perform a withstand voltage test on any part of the unit. This equipment uses sensitive devices and may be damaged by high
voltage.
The drive is not suitable for circuits capable of delivering more than the specified RMS symmetrical amperes. Install adequate branch short
circuit protection per applicable codes. Refer to the specification. Failure to do so may result in equipment damage and/or personal injury.
Do not connect unapproved LC or RC interference suppression filters, capacitors, or over voltage protection devices to the output of the
drive. Capacitors may generate peak currents that exceed drive specifications.
To avoid unnecessary fault displays, caused by contactors or output switches placed between drive and motor, auxiliary contacts must be
properly integrated into the control logic circuit.
YASKAWA is not responsible for any modification of the product made by the user, doing so will void the warranty. This product must not
be modified.
Verify that the rated voltage of the drive matches the voltage of the incoming power supply before applying power.
To meet CE directives, proper line filters and proper installation are required.
Some drawings in this manual may be shown with protective covers or shields removed, to describe details. These must be replaced before
operation.
Observe Electrostatic Discharge Procedures when handling the drive and drive components to prevent ESD damage.
The attached equipment may start unexpectedly upon application of power to the drive. Clear all personnel from the drive, motor and
machine area prior to applying power. Secure covers, couplings, shaft keys, machine beds and all safety equipment before energizing the
drive.

Introduction
This manual is intended as a parameter access quick reference guide for the Yaskawa model E7 drive. It describes how to connect the E7 drive
to an RS232, RS422 or RS485 network and access parameters and their values. It lists the available parameters, their addresses, limits, available
selections and default values. Refer to the
E7 Drive Programming Manual
for detailed parameter information.
This document pertains to the E7 drive. In this document, the word “inverter”, “ac drive” and “drive” may be used interchangeably.
For details on installation and operation of the E7 drive, refer to the
E7 Drive User Manual.
All manuals and support files are available on the
CD that came with the E7 drive and are also available for download at
