Product information

The Yaskawa GA500 Compact AC Drive (CIPR-GA50CB004AJAA-BAAASA) in finless execution is designed for optimized heat dissipation through an external heatsink, making it ideal for precise speed control of induction, permanent magnet, and synchronous reluctance motors. Operating on 1-phase 200–240 VAC power, it is rated for motors from 0.55 kW to 0.75 kW with a 3.0 A (HD) / 3.5 A (ND) output current. Key features include an IP20 finless housing without an internal EMC filter, integrated STO SIL3/PLe safety function, built-in braking chopper, and Modbus RTU communication via RS-485. Parameter setup is easily performed via the front mini-USB port.
