ABB ACS600, Eurotherm 601 series, and Yaskawa/Omron V7 drives are long out of production, but plenty of them are still doing daily work. Here's the case for keeping them running with pulled spares instead of a forced upgrade.
ABB's ACS600 Multidrive modules span a wide current range on the same platform. Here's what actually separates a 32A inverter module from a 178A one, and how to know which your motor needs.
When a line comes out, the drives, PLCs, and panels inside it are still worth something — if they're documented before the scrap trucks show up. A practical pre-teardown checklist.
A used drive is only a good deal if it's the right one. Here's what to verify on the nameplate before you order a replacement VFD, inverter, or drive module.
Retired lines and cabinet swaps leave working PLCs, VFDs, and I/O sitting on shelves. Here's a straight answer on what determines resale value and how to move it without leaving money on the table.
Sensor selection decides more machine uptime than almost any other component choice — a sensor in the wrong technology for its environment fails weekly, while the right one runs for a decade. Here is the practical decision guide across the…
Servo alarms look intimidating — dozens of codes across Fanuc, Lenze, Control Techniques, Siemens, and Yaskawa — but nearly all of them fall into five families with predictable field causes. Learn the families and you can diagnose most servo faults…
The humble 24 V DIN-rail power supply feeds everything that thinks in a modern panel — PLC, HMI, sensors, relays, network gear — and its failure takes all of them down at once. Sizing one properly is ten minutes of…
The touch panel is the machine’s face — and after 10–15 years of finger presses, heat, and 24/7 backlight duty, it is often the first thing to fail on an otherwise healthy line. Many popular Siemens generations (OP/TP 170/177/270 series,…
Variable frequency drives are prolific sources of conducted electromagnetic interference: fast-switching IGBT edges couple noise back into the mains, upsetting sensitive instruments sharing the supply and failing EMC compliance tests. A correctly sized line filter — such as Schaffner’s FN-series…
