Yaskawa G5 GPD515 Drive
The G5 GPD515 Drive produced an output of adjustable voltage and frequency to control the speed of a squirrel cage induction motor. This PWM design provided low motor noise and high starting torque. Current overload rating was 150% for 60 seconds. The drive provided 3 modes of control and speed accuracy to suit application requirements; V/Hz (2%), sensorless vector (0.1%), or flux vector control (0.01% with motor-mounted encoder and drive-mounted PG-X2 card required).
