Comparison Summary, Standard vs. DeviceNet Series

The Hitachi L100DN DeviceNet Series inverters generally have the same motor control capability as the standard L100 inverters. However, a few important differences do exist. The addition of DeviceNet network connectivity to Hitachi inverters is accompanied by some changes to the available parameters, functions, front panel keypad, and intelligent terminals. Together, these changes provide a complete inverter solution with DeviceNet network capability, while removing some features that are generally unused in networked applications.

DeviceNet Networking Overview

Hitachi L100DN DeviceNet Series inverters are optimized for use on a DeviceNet network. The inverter can respond to commands such as Run/Stop from a network host device, for example. L100DN inverters can also drive a motor in stand-alone mode, without a network connection. In that case, you use the inverter’s keypad or input terminals for Run/Stop commands. However, this addendum will use stand-alone operation only for initial powerup tests of your L100DN inverter during installation. After the installation material, the addendum covers network operation in detail.

The diagram below shows L100DN inverters connected to a DeviceNet network. Each connection is called a node, and the L100DN connects to the network via the 5-pin, color-coded Phoenix connector on the front panel as shown.

Network host computer L100DN inverter L100DN inverter

DeviceNet network

A DeviceNet network supports up to 64 devices, each with their own node address. One device will be the network master; all other device(s) will be network slaves. The L100DN inverter will operate as a network slave, as the network master (also called host computer) will send commands to the slaves.

A factory network such as DeviceNet allows you to integrate devices of many different types, even from various manufacturers, all into an integrated control system. A common application that uses DeviceNet is a conveyor line. Typical devices on the network include a PLC (programmable logic controller) or host computer (such as a PC), inverter drives to run motors, proximity sensors, limit switches, diverter actuators, barcode scanners, label printers, and other packaging or shipping devices. Note that Hitachi also provides the L100DN DeviceNet Series inverters, which can also reside on the DeviceNet network.

For detailed DeviceNet network configuration instructions, see “Network Control and Monitoring” on page 39.

Inverter Mounting and Installation

This section describes the L100 Series installation corresponding to Chapter 2, “Inverter Mounting and Installation,” in the L100 Inverter Instruction Manual.

Orientation to Inverter Features

Please take a few moments to unpack your new L100DN inverter and do these steps:

1. Look for any damage that may have occurred during shipping.

2. Verify the contents of the box include:

a. One L100DN inverter

b. One Addendum for L100DN inverter (read this addendum first!)

c. One L100 Instruction Manual

d. One L100DN Quick Reference Guide

e. One packet of desiccant—discard (not for human consumption)

3. Inspect the specifications label on the side of the inverter. Make sure it matches the

product part number you ordered.

L100DN Inverter

The L100DN DeviceNet Series inverters vary in size according to the current output rating and motor size for each model number. All feature the same basic keypad and connector interface for consistent ease of use. The inverter construction has a heat sink at the back of the housing. The larger models include a fan(s) to enhance heat sink performance. The mounting holes are pre-drilled in the heat sink for your convenience. Never touch the heat sink during or just after operation; it can be very hot.

The electronics housing and front panel are built onto the front of the heat sink. The front panel has two levels of physical access designed for convenience and safety:

• First-level access – for basic use of inverter, editing parameters, and wiring control signals or network connection (power ON)

• Second-level access – for wiring the inverter power supply or motor (power OFF)

1. First-level Access – View the unit just as it

came from the box as shown. The four-digit display can show a variety of performance parameters. LEDs indicate whether the display units are Hertz or Amperes. Other LEDs indicate AC Power (external), Run/ Stop Mode, Program/Monitor Mode, Module Status, and Network status. Membrane keys Run and Stop/Reset control motor operation. And, you can access the two chassis GND screws on the metal tab at the bottom of the inverter.

Inverter Mounting and Installation

The FUNC., , , and STR keys allow an operator to access and change the

inverter’s functions and parameter values. The top 8-position connector provides the interface for logic-level control signals. The bottom 5-position connector is the DeviceNet interface. It comes with a removable connector for connecting to a DeviceNet cable. These signals are generally low-voltage in nature and are appropriate for firstlevel access.

2. Second-level access – First, ensure no

power source of any kind is connected to the inverter. If power has been connected, wait five minutes after powerdown and verify the Power LED is OFF to proceed. Then locate the recessed retention screw on the left side main front panel (it is along the left hinge area on some models, or behind the first access door on others). Use a small screwdriver (Regular or Phillips) to loosen the screw. Swing the door around to the right to reveal the internal components of the drive. The twolevel tiered 12-position terminal block

Auxiliary network power connector

Retention screw

accepts wires for the power input and wires to the motor.

NOTE: The 3-terminal connector located on the circuit board behind the hinged front door can be used to connect DeviceNet network power. See “Step 2 – Connect Network Devices” on page 43 for more information.

Notice the housing partition that lifts out to allow full access to the terminals for wiring as shown. Never operate the inverter drive with the partition removed or the full access door opened.

Never directly touch any terminal or circuit component. This protects you from touching a n unexpected live circuit, and it protects the inverter from electrostatic discharge (ESD).

The power and motor connector terminals are accessible with the removal of the housing partition. The input power and motor connections use the lower row of terminals. The upper row is for connecting dynamic braking components.

System Description and Basic Installation

The Basic System Description and Step-by-Step Basic Installation sections in Chapter 2 of the standard L100 manual (included) will show you how to choose a mounting location and wire the inverter’s power input and motor output terminals. Wire gauge, terminal torque specifications, fuse or breaker size, and many important Warning and Caution messages are included. So, all of the information you need to physically install your L100DN DeviceNet inverter is in the standard manual—with the exception of the dimension drawings, which follow below.

NOTE: After doing the basic installation (physical mounting and power wiring) per the instructions in Chapter 2 of the L100 manual, be sure to return to this addendum for the Powerup Test and Front Panel Keypad orientation.

Inverter Mounting and Installation

Powerup Test Overview

After wiring the inverter and motor, you’re ready to do a powerup test. The procedure that follows is designed for the first-time use of the drive. Please verify the following conditions before conducting the powerup test:

• You have followed all the steps in this chapter up to this step.

• The inverter is new, and is securely mounted to a non-flammable vertical surface

• The inverter is connected to a power source and motor.

• No additional wiring of inverter connectors or terminals has been done.

• The power supply is reliable, and the motor is a known working unit, and the motor nameplate ratings match the inverter ratings.

• The motor is securely mounted, and is not connected to any load.

Goals for the Powerup test

If there are any exceptions to the above conditions at this step, please take a moment to take any measures necessary to reach this basic starting point. The specific goals of this powerup test are:

1. Verify that the wiring to the power supply and motor is correct.

2. Demonstrate that the inverter and motor are generally compatible.

3. Give a brief introduction to the use of the built-in operator keypad.

The powerup test gives you an important starting point to ensure a safe and successful application of the Hitachi inverter. We highly recommend performing this test before proceeding to the other chapters in this manual.

Pre-test and Operational Precautions

The following instructions apply to the powerup test, or to any time the inverter is powered and operating. Please study the following instructions and messages before proceeding with the powerup test.

1. The power supply must have fusing suitable for the load. Check the fuse size chart

presented in the inverter manual in Chapter 2, if necessary.

2. Be sure you have access to a disconnect switch for the drive input power if necessary.

However, do not turn OFF power during inverter operation unless it is an emergency.

CAUTION: The heat sink fins will have a high temperature. Be careful not to touch them. Otherwise, there is the danger of getting burned.

CAUTION: The operation of the inverter can be easily changed from low speed to high speed. Be sure to check the capability and limitations of the motor and machine before operating the inverter. Otherwise, there is the danger of injury.

CAUTION: If you operate a motor at a frequency higher than the inverter standard default setting (50Hz/60Hz), be sure to check the motor and machine specifications with the respective manufacturer. Only operate the motor at elevated frequencies after getting their approval. Otherwise, there is the danger of equipment damage and/or injury.

CAUTION: Check the following before and during the powerup test. Otherwise, there is the danger of equipment damage.

• Is the shorting bar between the [+1] and [+] terminals installed? DO NOT power or operate the inverter if the jumper is removed.

• Is the direction of the motor rotation correct?

• Did the inverter trip during acceleration or deceleration?

• Were the RPM and frequency meter readings as expected?

• Were there any abnormal motor vibrations or noise?

Powering the Inverter

If you have followed all the steps, cautions and warnings up to this point, you’re ready to apply power. After doing so, the following events should occur:

L100DN Inverter

• The POWER LED will illuminate.

• The numeric (7-segment) LEDs will display a test pattern, then stop at 0.0.

• The Hz LED will be ON. (This assumes the inverter is in Monitor Mode and is

displaying D_01, the output frequency.)

• The MS (Module Status) and NS (Network Status) LEDs will exhibit a test pattern;

each LED will briefly show green, then red. The ending state of powerup pattern is: MS = Green; NS = OFF.

If the motor starts running unexpectedly or any other problem occurs, press the STOP key. Only if necessary should you remove power to the inverter as a remedy.

NOTE: If the inverter has been previously powered and programmed, the LEDs (other than the POWER LED) may illuminate differently than as indicated above. If necessary, you can initialize all parameters to the factory default settings. See “Restoring Factory Default Settings” on page 94 or refer to the L100DN Quick Reference Guide.

Inverter Mounting and Installation

Using the Front Panel Keypad

Please take a moment to familiarize yourself with the keypad layout shown in the figure below. These are the visible controls and indicators when the front panel door is closed.

The display is used in programming the inverter’s parameters, as well as monitoring specific parameter values during operation. Many functions are applicable only during the initial installation, while others are more useful for maintenance or monitoring.

Keys, Modes, and Parameters

Purpose of the keypad is to provide a way to change modes and parameters. The term function applies to both monitoring modes and parameters. These are all accessible through function codes that are primarily 3-character codes. The various functions are separated into related groups identifiable by the left-most character, as the table shows.

For example, function “A_04” is the base frequency setting for the motor, typically 50 Hz or 60 Hz. To edit the parameter, the inverter must be in Program Mode (PGM LED will be ON). You use the front panel keys to first select the function code “A_04.” After displaying the value for “A_04,” use the Up/Down ( or ) keys to edit it.

NOTE: The inverter 7-segment display shows lower case “b” and “d,” meaning the same as the upper case letters “B” and “D” used in this manual (for uniformity “A to F”).

The inverter automatically switches into Monitor Mode when you access “D” Group functions. It switches into Program Mode when you access any other group, because they all have editable parameters. Error codes use the “E” Group, and appear automatically when a fault event occurs. Refer to

Keypad Navigational Map

The L100DN Series inverter drives have many programmable functions and parameters. Chapter 3 in the manual will cover these in detail, but you need to access just a few items to perform the powerup test. The menu structure makes use of function codes and parameter codes to allow programming and monitoring with only a 4-digit display and a few keys and LEDs. So, it is important to become familiar with the basic navigational map of parameters and functions in the diagram below.

Selecting Functions and Editing Parameters

In order to run the motor for the powerup test, this section will show how to:

• select the inverter’s maximum output frequency to the motor

• set the value of parameter F_01 to the output frequency for the powerup test

• select the keypad as the source of the RUN command

The following series of programming tables are designed for successive use. Each table uses the previous table’s final state as the starting point. Therefore, start with the first and continue programming until the last one. If you get lost or concerned that some of the other parameters settings may be incorrect, refer to “Restoring Factory Default Settings” on page 94.

Setting the Motor Base Frequency – The motor is designed to operate at a specific AC frequency. Most commercial motors are designed for 50/60 Hz operation. First, check the motor specifications. Then follow the steps in the table below to verify the setting or correct for your motor. DO NOT set it for greater than 50/60 Hz unless the motor manufacturer specifically approves operation at the higher frequency.

Inverter Mounting and Installation

Select the Keypad for the RUN Command – The RUN command causes the inverter to accelerate the motor to the selected speed. For local (non-network) inverter control, you can program the inverter to respond to either the control terminal signal (default) or the keypad RUN key. Follow the steps in the table below to select the front panel RUN key as the source for the RUN Command (the table resumes action from the end of the previous table).

L100DN Inverter

Set the Output Frequency – Note that the standard L100 Series inverter uses parameter A_01 Frequency Source Setting to select from sources that include a front panel potentiometer and input terminals. In contrast, the L100DN DeviceNet inverter is optimized for network control and does not have these two alternate frequency sources. Therefore, the L100DN does not need (or have) parameter A_01. The default frequency source for the L100DN is setting F_01 Output Frequency Setting. The frequency setting works in the following way:

• Operator (local) Control – When using the inverter’s front panel Run and Stop keys to control the motor, the inverter uses parameter F_01 Output Frequency Setting.

• Network Control – When the inverter is under network control, Run and Stop commands typically arrive via the network. In this case, you have the additional option of using the inverter’s parameters (includes F_01 Output Frequency Setting), or the network host device can send the output frequency setting via the network upon each network scan. More details are in “Network Control and Monitoring” on page 39.

This step in the powerup test will set F_01 Output Frequency Setting to 15Hz.

CAUTION: Be sure to set F_01 Output Frequency Setting to a safe value for your motor and application. The step below only uses 15Hz as an example.

TIP: If you became lost during any of these steps, first observe the state of the PRG LED. Then study the “Keypad Navigational Map” on page 20 to determine the current state of the keypad controls and display. As long as you do not press the STR key, no parameters will be changed by keypad entry errors. Note that power cycling the inverter will not cause it to reset to a particular programming state.

Monitoring Parameters with the Display

After using the keypad for parameter editing, it’s a good idea to switch the inverter from Program Mode to Monitor Mode and close the panel door (puts the keys for parameter editing out of sight). This will also turn out the PRG LED, and the Hertz or Ampere LED indicates the display units.

For the powerup test, monitor the motor speed indirectly by viewing the inverter’s output frequency. The output frequency must not be confused with base frequency (50/60 Hz) of the motor, or the carrier frequency (switching frequency of the inverter, in the kHz range). The monitoring functions are in the “D” list, located near the top left of the “Keypad Navigational Map” on page 20.

Running the Motor

If you have programmed all the parameters up to this point, you’re ready to run the motor! First, review this checklist:

1. DO NOT connect the inverter to the DeviceNet network or supply +24V network

power yet.

2. Verify the Power LED and Module Status (MS) LEDs are ON (green, not flashing). If

not, check the power connections.

3. Verify the Run Key Enable LED is ON. If not, review the programming steps to find

the problem.

4. Verify the PRG LED is OFF. If it is ON, review the instructions above.

5. Make sure the motor is disconnected from any mechanical load.

6. Now, press the RUN key on the keypad. The RUN LED will turn ON.

7. The motor should accelerate to 15.0 Hz, and the display will indicate “15.0.”

8. Press the STOP key to stop the motor rotation.

Powerup Test Observations and Summary

Reading this section will help you make some useful observations when first running the motor.

Error Codes – If the inverter displays an error code (format is “E x x”), see Chapter 6 in the L100 instruction manual for instructions on how to interpret and clear the error.

Acceleration and Deceleration - The L100DN inverter has programmable acceleration and deceleration values. The test procedure left these at the default value, 10 seconds. You can observe this by setting the potentiometer at about half speed before running the motor. Then press RUN, and the motor will take 5 seconds to reach a steady speed. Press the STOP key to see a 5 second deceleration to a stop.

State of Inverter at Stop – If you adjust the motor’s speed to zero, the motor will slow to a near stop, and the inverter turns the outputs OFF. The high-performance L100DN can rotate at a very slow speed with high torque output, but not zero (must use servo systems with position feedback for that feature). This characteristic means you must use a mechanical brake for some applications.

Interpreting the Display - First, refer to the output frequency display readout. The maximum frequency setting (parameter A_04) defaults to 50 Hz or 60 Hz (Europe and United States, respectively) for your application.

L100DN Inverter

Example: Suppose a 4-pole motor is rated for 60 Hz operation, so the inverter is configured to output 60 Hz at full scale. Use the following formula to calculate the RPM.

Speed in RPM

Frequency 60×

----------------------------------------

Pairs of poles

Frequency 120×

---------------------------------------- ---

# of poles

60 120×

--------------------- 1800RPM== == 4

The theoretical speed for the motor is 1800 RPM (speed of torque vector rotation). However, the motor cannot generate torque unless its shaft turns at a slightly different speed. This difference is called slip. So it’s common to see a rated speed of approximately 1750 RPM on a 60 Hz, 4-pole motor. Using a tachometer to measure shaft speed, you can see the difference between the inverter output frequency and the actual motor speed. The slip increases slightly as the motor’s load increases. This is why the inverter output value is called “frequency,” since it is not exactly equal to motor speed. You can program the inverter to display output frequency in units more directly related to the load speed by entering a constant (discussed in Chapter 3 in the L100 instruction manual).

Run/Stop Versus Monitor/Program Modes –

The Run LED on the inverter is ON in Run Mode, and OFF in Stop Mode. The Program LED is ON

when the inverter is in Program Mode, and OFF for Monitor Mode. All four mode combinations are possible. The diagram to the right depicts the modes and the mode transitions via keypad.

FUNC.

NOTE: Some factory automation devices such as PLCs have alternate Run/Program modes; the device is in either one mode or the other. In the Hitachi inverter, however, Run Mode alternates with Stop Mode, and Program Mode alternates with Monitor Mode. This arrangement lets you program some values while the inverter is operating— providing flexibility for maintenance personnel.

NOTE: The assignment of [DNT] to an input terminal is optional. It is useful if you need to switch between DeviceNet network control and local control during running. Alternatively, you can use parameter P_43 DeviceNet Control Enable, which works similarly but does not require an input terminal. If assigned, the [DNT] setting has precedence over the P_43 setting. More information is in “Step 7 – Control Test – Verify Network Host Can Control Inverter” on page 54.

L100DN Inverter

Intelligent Output Terminals – The L100DN DeviceNet Series inverters have 5 of the 6 possible output option assignments for standard L100 inverters ([OD] is removed). However, note that the alarm relay contact terminals [AL0], [AL1], and [AL2] are not present on the L100DN DeviceNet Series inverters (so C_24 and C_33 are not present on L100DN).
