Micro AC Crane Drive • Crane specific software allows for start-up in 15 minutes or less • Pre-configured reference options result in simple and uniform setup from job to job: – Up to five fixed speeds – Two-step infinitely variable – Stepless 0-10 VDC & 4-20mA
• Built-in protective features increase crane reliability and up-time:
– High precision current detection – Full overload protection – Overvoltage/overcurrent stall protection – Short circuit protection – Reset after fault – Motor overheat protection
• Units can be mounted side-by-side, reducing panel space requirements by 10% ACCel30™ Micro AC Crane Drive Avtron’s ACCel30™ AC drive provides crane travel and open loop hoist control using FastDrive™ software technology – commissioning is completed quickly in 15 minutes or less. Its compact, modular design, and its high-efficiency cooling system allow several ACCel30™ drives to be stacked together to significantly reduce panel space requirements for multi-motion applications. Optional DIN rail mounting kits reduce installation times. The ACCel30™ AC drive’s rugged design stands up to the demanding environment of a crane. It meets CMAA BULLETIN 492 REV. -
class A, B, C, D, and E service requirements for cranes, and it carries a 50°C ambient rating. Several standard industrial communication options provide a powerful complement to the standard drive package. By using protocols such as DeviceNet, Profibus, or CANopen, the ACCel30™ drive can be integrated into larger or automated systems with Radio Controllers, PLC’s, and Sway Controls. All drive models have a built-in brake chopper, reducing wiring cost and panel space. An optional external
resistor is available to provide braking capabilities. Several ACCel30™ drives can be tied together through the DC bus, enabling multiple drives to share regenerative energy, resulting in overall energy savings. The ACCel30™ drive is available in ratings from 0.25 to 20 hp @ 230 VAC, and 0.5 to 30 hp @ 460 VAC. Each drive is supplied with a keypad for easy configuration and troubleshooting by technicians. Built-in, 120 VAC inputs require no external adapters.
