Rockwell Automation Publication 290D-UM001A-EN-P - June 2012 19

Chapter 1 Product Overview

Feature Description

Standard Features Across Product Family

UL Listed “Suitable for Group Motor Applications” — Where NFPA 70 (NEC) or 79 are required installation standards, this Listing allows two or more motors to be connected to the same branch circuit without individual motor branch short circuit or ground fault protection. Refer to Appendix A for details.

At-motor disconnect switch — ArmorStart LT offers a local ON/Off motor disconnecting means with lockout-tagout provision. Industrial standards require a local at-motor disconnect to be within eye sight of the motor for maintenance or other shutdown reasons. Refer to your installation code for details.

User configurable I/O — ArmorStart LT offers 6 user configurable I/O points to be used with sensors and actuators. By default all 6 points are configured as sinking 24V DC inputs. The user has the option to select any point as a sourcing 24V DC output.

DeviceNet Network Capabilities

The ArmorStart Distributed Motor Controller delivers advanced capabilities to access parameter settings and provides fault diagnostics, and remote start-stop control.

DeviceLogix — ArmorStart LT offers local programmable logic via DeviceLogix. DeviceLogix is a stand-alone program that resides within the ArmorStart LT. It is programmed locally using the Add-On-Profile and implements operations such as, AND, OR, NOT, Timers, Counters, Latches, and Analog operations. DeviceLogix can run as a stand-alone application, independent of the network or collaboratively with the PLC. However, unswitched control power must be maintained for DeviceLogix to operate.

Zone Interlock Protocol (ZIP) — The zone control capabilities of ArmorStart LT is ideal for motored conveyors. Zone Interlocking Parameters (ZIP) allow one ArmorStart to receive data directly, from up to four other DeviceNet nodes, without going through a network scanner. These direct communications between conveyor zones are beneficial in a merge, diverter, or accumulation conveyor application.

Quick disconnect for I/O and network — ArmorStart LT offers quick disconnect connectors for I/O and communications.

DeviceNet node address — ArmorStart LT offers external accessible address switches for device node address configuration. The address can be set statically or dynamically.

EMI filter — ArmorStart LT for VFD application (Bulletin 294) provides an internal EMI filter and is CE compliant. For CE compliant installations refer to the recommended EMI/RFI cord grip accessory. For availability of the quick

20 Rockwell Automation Publication 290D-UM001A-EN-P - June 2012

Product Overview Chapter 1

disconnect shielded motor cable contact your local sales representative for details.

Local and remote status and diagnostics — ArmorStart LT offers comprehensive status and diagnostics for I/O, Network, and device health via 12 LEDs found on the electronic control module (ECM). If a fault occurs a local fault reset button allows the user to quickly get the process started after corrective action is taken. The user can also configure the embedded web server to send an e-mail when a fault or warning occurs.

Gland plate entrance — ArmorStart LT offers different methods of connecting three-phase, control power, and motor. ArmorStart LT has conduit entrance openings, as standard.

Factory-Installed Options

Internal power supply (IPS) — ArmorStart LT offers the user an optional 24V DC internal power supply. The internal power supply provides all control and I/O power needs and is sourced from the incoming 3-phase power. This eliminates the need to run separate control power to each unit, reducing installation time and cost. The local at-motor disconnect will remove power from the motor terminals and outputs when in the OFF condition.

Hand/Off/Auto (HOA) keypad — ArmorStart LT offers an optional local Hand-Off-Auto keypad. This key pad allows local start/stop motor control regardless of PLC status. This option can be used for troubleshooting or maintenance operations. The HOA can also be disabled when local control is not allowed, using parameter 67.

Source brake — ArmorStart LT provides an optional, internally-controlled electromechanical motor brake contactor. The motor brake power is sourced from 3-phase power, L1 and L2.

Quick disconnect gland — ArmorStart LT offers a plug -n- play solution that simplifies wiring and installation. These factory installed quick disconnect receptacles provide connectivity to ArmorConnect® media for three-phase, control, and motor connections. The cables are ordered separately.

Basic Operation

Group Motor Installations for USA and Canada Markets

The ArmorStart LT Distributed Motor controllers are listed for use with each other in group installations per NFPA 79, Electrical Standard for Industrial Machinery and NFPA 70, the National Electrical Code. When applied according to the group motor installation requirements, two or more motors are permitted on a single branch circuit. Group Motor Installation has been successfully used for many years in the USA and Canada.

Note: For additional information regarding group motor installations with the ArmorStart LT Distributed Motor Controller, see Appendix A

Control Circuit

ArmorStart LT accepts a 24V DC Class 2 input power supply for switched and unswitched power. The control voltage provides power to the inputs (unswitched) and outputs (switched). Unswitched control voltage is used to ensure no loss of network connectivity, sensor, or other field input status under normal operation. The control power terminal connections are labeled A1, A2, and A3. Switched power is identified as (+A1) (-A2). Unswitched power is identified as (+A3) (-A2).

As an option, ArmorStart LT can be supplied with an internal power supply (IPS) eliminating the need for an external control power. The IPS is sourced from the line side of 3-phase power and is not impacted by the status of the local atmotor disconnect switch.

Mode of Operation Bulletin 294D

Sensorless Vector Performance

Using a distributed AC drive to operate mechanical equipment at optimum speed helps reduce energy costs and eliminates mechanical wear and tear that can occur in the mechanical parts. The advance monitoring found in ArmorStart LT protects critical equipment against unplanned downtime with advanced diagnostics and notification of irregular operating parameters. ArmorStart LT provides open-loop speed regulation (V/Hz) with slip compensation. This provides excellent speed regulation and high levels of torque across the entire speed range of the drive, and improved speed regulation as loading increases.

Open Loop Speed Regulation with Slip Compensation allows the VFD to automatically adjust the output frequency to compensate for speed changes due to motor loading. This feature utilizes an open loop, current feedback, slip compensation circuit. Slip Compensation works as an open loop speed regulator that increases the output frequency of the drive as the load is increased, or decreases the frequency as the load drops. This feature is used where the motor must run at a relatively constant speed regardless of torque output.

Electronic Data Sheet (EDS)

ArmorStart LT EtherNet/IP has an embedded electronic data sheet. An EDS consists of specially formatted text files, as defined by the CIP™. EDS files contain details about the readable and configurable parameters of the device. They also provide information about the I/O connections that the device supports and the content of the associated data structures. EDS are used by device configuration tools, such as RSNetWorx™, and data servers such as RSLinx® Classic.

EDS files for all ArmorStart LT devices can be uploaded directly from the device via the web server interface. Rockwell Automation product EDS files are also available on the internet at: http://www.ab.com/networks/eds
