This document outlines the process of replacing an external Elapsed Time Meter (ETM) with the built-in ETM functionality available on the keypad of ABB's 580-drive series (ACH580, ACQ580, and ACS580). The primary function of an ETM is to track equipment run times, which is crucial for scheduling maintenance activities. Traditionally, a separate ETM would be installed on the VFD control panel, but this document demonstrates how the integrated ETM on the keypad can serve the same purpose, offering a more cost-effective and streamlined solution.
The ETM functionality on the 580-drive series keypad provides a non-resettable counter that tracks the operational duration of the Variable Frequency Drive (VFD). This built-in ETM eliminates the need for external hardware, reducing installation complexity and associated costs. It can display the VFD's operational time in various formats, including hours and days, offering flexibility in how maintenance schedules are managed. The ETM is accessible directly from the keypad's "home view," meaning users do not need to navigate through complex parameter menus to retrieve the information. This direct accessibility enhances user convenience and efficiency in monitoring equipment usage. The ETM data, being integrated into the VFD's control system, can also be communicated to a SCADA (Supervisory Control and Data Acquisition) system, providing a more comprehensive and automated approach to data logging and maintenance planning compared to standalone ETMs that lack communication capabilities.
The built-in ETM on the 580-drive series keypad offers several user-friendly features for accessing and configuring run-time information. To access the ETM functionality, users navigate through the keypad menu by selecting "Options," then "Edit Home view," and finally choosing a "Screen Location" to insert the ETM. From there, they can select "Parameter," then "Other," "05 Diagnostics," and specifically "05.03 Hours run (hours)" or "05.02 Run-time counter (days)." This structured navigation allows users to customize the home screen to display the most relevant run-time information.
The keypad allows for the display of up to three parameters per panel home screen, enabling users to monitor multiple aspects of the VFD's operation simultaneously. For instance, users can choose to display the "Hours run" counter, which indicates the total number of hours the VFD has powered the motor. Alternatively, they can select the "On-time counter," which displays the number of days the VFD has been powered. This flexibility in display options caters to different maintenance strategies and reporting requirements. The process of adding these counters to the home screen involves selecting an empty display slot, choosing the desired parameter, and confirming the selection. The intuitive menu structure, combined with clear on-screen prompts, simplifies the configuration process, making it accessible even for users who may not be deeply familiar with VFD programming. The ability to quickly navigate to the run-time counter home screen ensures that critical operational data is always just a few button presses away.
The ETM functionality significantly enhances maintenance planning and execution for VFDs. By accurately tracking the operational hours or days of the VFD, maintenance teams can implement preventive maintenance schedules based on actual equipment usage rather than arbitrary time intervals. This usage-based approach helps optimize maintenance efforts, preventing premature component wear and extending the lifespan of the VFD and associated equipment. For example, knowing the exact hours a motor has run allows for timely lubrication, filter changes, or other routine checks, reducing the risk of unexpected breakdowns and costly downtime.
The non-resettable nature of the built-in ETM ensures data integrity, providing a reliable historical record of equipment operation. This historical data is invaluable for troubleshooting, performance analysis, and warranty claims. Furthermore, the integration of the ETM into the VFD's control panel eliminates the need for separate wiring and relays that would be required for an external ETM. This reduces the number of potential failure points and simplifies the overall system architecture, making maintenance of the control panel itself more straightforward. The ability to communicate run-time information to a SCADA system further streamlines maintenance by enabling centralized monitoring and automated alerts, allowing maintenance personnel to proactively address potential issues before they escalate. This comprehensive approach to run-time tracking and data management ultimately leads to more efficient, reliable, and cost-effective maintenance operations for the 580-drive series.
