Drive Prolonged Performance: Why VFD Maintenance Is a Must
In today’s high-paced industrial world, variable frequency drives (VFDs) might seem like “set it and forget it” devices—but that mindset can lead to unexpected, costly failures. At IC-Spares, we know that even the most reliable systems—whether they’re our Siemens Perfect Harmony GH180, WEG MVW01, Benshaw, Toshiba, or Yaskawa drives, or even our rental units—require regular, proactive care to stay in peak condition. Why Routine Maintenance Matters While modern VFDs are engineered for durability, neglecting periodic maintenance can transform a minor issue into a major system shutdown. Think of it like regular oil changes for your car: a little effort now can prevent expensive repairs later. In fact, studies (such as those reported by IEEE) have shown that a significant portion of equipment failures is linked to inadequate or improper maintenance. By investing in routine check-ups, you can avoid unexpected downtime and extend the lifespan of your drive. What Does “Routine” Mean? There’s no one-size-fits-all answer when it comes to maintenance schedules, but here at IC-Spares we generally advise that medium voltage VFDs receive at least an annual inspection. In more demanding environments such as heavy industrial settings with high dust or temperature extremes, a biannual review can be a lifesaver. Key Areas to Focus On 1. Tighten Up Loose Connections Loose wiring, whether in high-current power circuits or low-voltage control panels, is one of the leading causes of VFD issues. Over time, vibration and thermal cycling can lead to connections that are less secure, resulting in arcing, oxidation, and excessive heat. Regularly checking and tightening these connections can prevent intermittent faults and more severe failures down the line. 2. Clear Out Contaminants VFDs operating in harsh environments such as manufacturing floors, mining sites, or outdoor installations are prone to collecting dust, oil, and other debris. These contaminants can clog cooling fins and heat sinks, impairing the drive’s ability to dissipate heat and potentially leading to premature component failure. Keeping the internals clean is essential to maintain optimal thermal performance and avoid costly repairs. 3. Listen and Look for Warning Signs Skilled technicians know that sometimes the earliest indicators of a problem are audible or visual. Unusual sounds from a transformer or chattering relays, or visual signs such as discoloration or scorch marks, can signal that components are nearing failure. 4. Familiarize Yourself with Your System Scheduled maintenance isn’t just about fixing problems, it’s also an excellent opportunity to get acquainted with your system’s layout and unique characteristics. By knowing where key components are located and how they operate, your team will be better prepared to act swiftly in an emergency. Consider routine maintenance as hands-on training that pays dividends in reduced stress and faster troubleshooting when issues arise. 5.

Beat the Heat: Protect Your Medium Voltage Drive
Modern medium voltage drives are the workhorses’ powering industries from water treatment and cement production to mining and manufacturing. At IC-Spares, we offer a range of industry-leading drives, including Siemens Perfect Harmony GH180, WEG MVW01, Benshaw, Toshiba, and Yaskawa models that keep your operations running smoothly. Even the best equipment can suffer under harsh conditions if not properly cared for. The Heat Is On Take, for example, a 6900V drive rated at 5000HP. Under full load, this industrial giant can generate over 100 kW of heat—an amount of thermal energy comparable to a small power plant. Without an efficient cooling system to manage this heat, your drive could overheat, potentially leading to shutdowns or long-term damage.

GE SPEEDTRONIC™ Mark VI Turbine Control System Architecture
The SPEEDTRONIC™ Mark VI turbine control is designed as a complete integrated control, protection, and monitoring system for generator and mechanical drive applications of gas and steam turbines. It is also an ideal platform for integrating all power island and balance-of-plant controls. Hardware and software are designed with close coordination between GE’s turbine design engineering and controls engineering to insure that your control system provides the optimum turbine performance and you receive a true “system” solution. Architecture The heart of the GE SPEEDTRONIC™ Mark VI Turbine Control System is the Control Module, which is available in either a 13- or 21- slot standard VME card rack. Inputs are received by the Control Module through termination boards with either barrier or box-type terminal blocks and passive signal conditioning. Each I/O card contains a TMS320C32 DSP processor to digitally filter the data before conversion to 32 bit IEEE-854 floating point format. The data is then placed in dual port memory that is accessible by the on-board C32 DSP on one side and the VME bus on the other. In addition to the I/O cards, the Control Module contains an “internal” communication card, a main processor card, and sometimes a flash disk card. Each card takes one slot except for the main processor that takes two slots. Cards are manufactured with surface-mounted technology and conformal coated per IPC-CC830. I/O data is transmitted on the VME backplane between the I/O cards and the VCMI card located in slot 1. The VCMI is used for “internal” communications between: I/O cards that are contained within its card rack I/O cards that may be contained in expansion I/O racks called Interface Modules I/O in backup <P> Protection Modules I/O in other Control Modules used in triple redundant control configurations The main processor card The main processor card executes the bulk of the application software at 10, 20, or 40 ms depending on the requirements of the application. Since most applications require that specific parts of the control run at faster rates (i.e. servo loops, pyrometers, etc.), the distributed processor system between the main processor and the dedicated I/O processors is very important for optimum system performance. A QNX operating system is used for real-time applications with multi-tasking, priority-driven preemptive scheduling, and fast-context switching. Communication of data between the Control Module and other modules within the Mark VI control system is performed on IONet. The VCMI card in the Control Module is the IONet bus master communicating on an Ethernet 10Base2 network to slave stations. A unique poling type protocol (Asynchronous Drives Language) is used to make the IONet more deterministic than traditional Ethernet LANs. An optional Genius Bus™ interface can be provided on the main processor card in Mark VI Simplex controls for communication with the GE Fanuc family of remote I/O blocks. These blocks can be selected with the same software configuration tools that select Mark VI I/O cards, and the data is resident in the same database. The Control Module is used for control, protection, and monitoring functions, but some applications require backup protection. For example, backup emergency overspeed protection is always provided for turbines that do not have a mechanical overspeed bolt, and backup synch check protection is commonly provided for generator drives. In these applications, the IONet is extended to a Backup Protection Module that is available in Simplex and triple redundant forms. The triple redundant version contains three independent sections (power supply, processor, I/O) that can be replaced while the turbine is running. IONet is used to access diagnostic data or for cross-tripping between the Control Module and the Protection Module, but it is not required for tripping.
