Yaskawa's GPD 305/J7 is a general purpose AC drive for use with squirrel cage induction motors. This PWM design provides low motor noise and high starting torque. The current overload rating is 150% for 60 seconds. The GPD 305/J7 provides V/Hz control suitable for most general applications.

The GPD 305/J7 is a feature-packed, low cost, compact drive. The digital operator includes a 3-digit LED status display and an analog speed potentiometer. Digital programming covers 79 parameters suitable for many applications. The four standard multifunction inputs can be programmed to allow for 9 preset speeds. The GPD 305/J7 also has an analog input, a multifunction output, and an analog output as standard.

An optional RS-485 Modbus RTU serial communication port is available with up to 32 nodes on a single network.

The GPD 305/J7 is ideal for applications such as conveyors, grinders, centrifuges, pumps, fans and blowers used in material handling, packaging, food processing, and commerical laundry.

The GPD 305/J7 is available in open chassis from 1/8 to 5 HP at 230 VAC and 1/4 to 5 HP at 460 VAC. NEMA 4/12 also available upon request. GPD 305/J7; an ideal choice whenever excellent performance, low cost, and small size are required.
