Comprehensive Customization Services for Drive Systems
Low-voltage drive companies offer extensive customization to meet specific application requirements beyond their standard product offerings. These services can be broadly categorized into three main areas: Hardware Customization, Firmware/Software Customization, and PC Software (HMI/SCADA) Customization.
1. Hardware Customization
Hardware customization involves modifying the physical components and electrical characteristics of the drive.
- Custom I/O (Input/Output) Configuration:
Adding, removing, or changing the types of digital and analog I/O points. This can include extra relay outputs for alarms, specific voltage/current inputs for sensors, or high-speed digital inputs for encoder feedback.
Communication Protocol Integration:
Integrating specific industrial communication interfaces and protocols directly onto the drive’s main board or via an add-on module. Common examples include PROFINET, EtherCAT, EtherNet/IP, Modbus TCP, and CANopen.
Specialized Filtering and Shielding:
Customizing the built-in or external filters to meet strict Electromagnetic Compatibility (EMC) standards for sensitive environments, such as medical facilities or laboratories.
Environmental and Mechanical Adaptations:
Modifying the drive enclosure for specific environmental conditions, such as conformal coating for protection against humidity and dust, or designing custom heat sinks for non-standard cooling methods.
Custom Power Stages:
Designing the power electronics (IGBTs, rectifiers) for unique voltage, current, or power requirements that fall outside standard product ranges.
2. Firmware & Software Customization
This involves modifying the embedded software (firmware) that controls the drive’s core functionality.
- Application-Specific Logic and Control Laws:
Implementing custom control algorithms (e.g., specialized PID loops, tension control, synchronization) and sequencing logic tailored to a specific machine’s operational workflow.
- Custom Parameter Sets and User Interfaces:
Simplifying the user experience by creating application-specific parameter groups, hiding irrelevant parameters, and renaming others to match industry-specific terminology.
- Modified Motor Control Algorithms:
Tuning or adapting sensorless vector control, field-oriented control (FOC), or V/f patterns to optimize performance for non-standard motors (e.g., submersible motors, high-pole count motors).
- Data Logging and Diagnostics:
Programming the drive to capture and store specific operational data (e.g., peak currents, temperature profiles, event timestamps) for diagnostics and predictive maintenance.
- Safety Function Integration:
Configuring and certifying integrated safety functions (e.g., Safe Torque Off – STO, Safely Limited Speed – SLS) according to specific safety performance levels (SIL, PL).
3.PC Software &HMI/SCADA Customization
This focuses on the development of custom software for monitoring, controlling, and integrating the drive system from a computer or central operator station.
- Custom Configuration Tools:
Developing dedicated PC software to simplify the setup, commissioning, and parameter management of drives for a specific machine or application, often replacing the drive’s standard complex software.
- Proprietary Communication Drivers:
Creating custom communication drivers to enable data exchange between the drives and a proprietary or legacy HMI/SCADA system that does not support standard protocols.
- Custom HMI (Human-Machine Interface) Screens:
Designing and developing tailored graphical user interfaces for operator panels or touchscreens. These screens display relevant drive data (speed, torque, alarms) and controls in a layout optimized for the machine operator.
- SCADA (Supervisory Control and Data Acquisition) Integration:
Building custom SCADA application screens, alarm management systems, and historical data trending features to integrate multiple drives into a central plant-wide monitoring and control system.
- Data Analytics and Reporting Dashboards:
Developing advanced software applications that collect data from multiple drives, perform analytics (e.g., energy consumption analysis, performance degradation), and present the results on custom web-based or desktop dashboards.
By leveraging these customization services, customers can achieve seamless integration, enhanced performance, and a competitive edge for their specialized machinery and processes.
