The Inovance CS300‑4T18.5GB is a 18.5kW three‑phase 380V crane‑special variable frequency drive, widely adopted for hoisting, traversing and slewing control of small‑medium lifting equipment. As a core model of the CS300 series, this VFD delivers stable and reliable motor regulation for overhead cranes, gantry cranes and material‑handling machinery.
It supports sensorless open‑loop vector control and V/F control modes, offering 200% high starting torque at 0.5Hz, 1:100 speed‑adjustment range and ±0.5% steady‑speed accuracy to prevent load slipping during heavy‑duty startup. Rated output current reaches 37A, with strong overload capacity: 150% rated current for 1 minute and 180% for 2 seconds to handle frequent lifting shock loads. Built‑in dedicated brake timing logic optimizes hoisting safety performance.
Rich I/O terminals, multi‑speed function and Modbus communication simplify on‑site wiring and commissioning. Comprehensive protection covers over‑current, over‑voltage, under‑voltage, over‑heat and phase loss, with 41 fault codes for quick troubleshooting. CE‑certified complying with international standards, Inovance CS300‑4T18.5GB stands out as a cost‑effective, low‑maintenance drive solution for global crane automation projects.
