Modbus variable frequency drive VariMax™

DIN rail mountedPROFIBUSEtherCAT

VariMax™ Variable Frequency Drives (VFDs) offer custom speed ranges while minimizing power consumption. Sized on amps rather than horsepower, these AC systems save energy compared to typical rotor systems since excess power isn't wasted by secondary resistors. Additionally, they reduce the required control space on the cranes. • Easy to Install and Use • Energy Efficient • Easy Diagnostics • Maintenance Savings • Configurable Parameters • Remote Monitoring • Expandable I/O, DeviceNet, Profibus, EtherCAT, Modbus and Profinet • Built in Dynamic Braking Module VariMax® VFDs are ideal for hoist movement with overhauling loads, allowing travel motions without the need for feedback. With drive-to-drive connect, the VFDs can prevent skewing and utilize anti-sway technology. Additionally, they reduce the required control space on cranes. Seamless setup and convenient upkeep are guaranteed with our VFDs. The System is fully integrated on panel with DIN rail mounted components and terminal blocks. Also, on-board diagnostics can be accessed on the drive, or remotely by smart phone and laptop.
