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 remain 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 no liability for any personal injury, property damage, losses, or claims arising from misapplication of its products.

WARNING

 Read and understand this manual before installing, operating, or servicing this drive. All warnings, cautions, and instructions must be

followed. Qualified personnel must perform all activity. 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

The Metasys N2 protocol is considered a CASE option for the P7U drive and is not included in the standard P7U drive. If the Metasys N2 protocol is necessary, make sure that the correct drive has been ordered and received.

This manual explains the specifications and handling of the Metasys N2 protocol for the Yaskawa model P7U drive. The P7U drive with the Metasys N2 protocol selected, connects the P7U drive to a Metasys N2 network and facilitates the exchange of data.

This document pertains to the Yaskawa P7U drive. Additionally, in this document, the word “inverter”, “ac drive” and “drive” may be used interchangeably.

To ensure proper operation of this product, read and understand this manual. For details on installation and operation of the P7U drive or details on specific P7U parameters, refer to the P7U User Manual, document reference TM.P7.01. For details on P7U MODBUS communications, refer to the P7U MODBUS are on the CD that was supplied with the drive and available for download at www.drives.com.

Installation Check Sheet

The following is a quick reference guide to the installation and configuration of the P7U drive with the Metasys N2 protocol. Make a copy of this page and check-off each item as it is completed. For detailed information please refer to the detailed sections that follow.

1: Unpack the drive and verify that all components are present and undamaged.

2: Connect power to the drive and verify that the drive functions. This includes running the drive in local mode from the

digital operator without the network selected or connected. Refer to the P7U User Manual for more information on connecting and operating the drive.

3: Remove power from the drive and wait for the charge lamp to be completely extinguished. Wait at least five additional

minutes after all indicators are off. Measure the DC bus voltage and verify that it is at a safe level.

4: Connect the drive to the Metasys N2 communication network. Refer to Chapter 2 – Network Connection for the Metasys

N2 connection procedure.

5: If this drive is either the first or the last device on the network, set the terminating resistor switch, S1-1, to ON. If this

device is not the first or last device on the network, set the terminating resistor switch, S1-1, to OFF. Refer to Chapter 2 –

Network Connection for details.

6: Configure the Metasys N2 network for the drive as a VND device. Refer to the documentation included with the Metasys

N2 configuration software.

7: Set parameters b1-01, b1-02, H5-01, H5-02 and H5-08 to their appropriate values. Refer to Table 1.1 - Drive

Communication Parameter Settings on page 1-5.

Metasys N2 Set-Up

A Ya skawa Electric America, Inc. (YEA) representative is responsible for proper configuration of the drive for its primary application, while a Johnson Controls, Inc. representative is responsible for field panel programming to make use of the drive’s functionality in the building automation system as a VND device. As such, there must be coordination between the Yaskawa Electric America and Johnson Controls representatives to ensure that the programming of the drive is consistent with the particular application requirements. After verifying that the drive installation and wiring are correct, apply power to the drive. Table 1.1 below lists the parameters and their values required for proper Metasys N2 communication and control.
