Frequency inverter/AC drive/inverter(B501 series)adpot Yaskawa G3 series techonology and software, are high-performanced general-purpose sensorless vector inverter. Combined with motor parameters auto tuning function, B501 series can auto detect motor parameters and auto set correlative control parameters. B501 series have three selectable control modes: V/F, V/F with PG and sensorless vector control which provided the functions of auto torque boost in all speed range, auto torque compensation and silence steady operation.

Main features:
1)Power range: Three phase 220V 1HP-50HP(0.75KW-37KW)
Three phase 380V 1HP-100HP(0.75KW-75KW)
2)Input Voltage: 3-phase 220V/3-phase 380/415V +10%~-15%, 50/60Hz
3)Output frequency: 0.1-400Hz
4)Control mode: SPWM control, VF+PG control, speed sensorless vector control
5)Inbuild PID control
6)AVR function
7)Modbus control with RS485 communication
8)Auto-adjusting motor torque and motor protection
