 P type model: 0.5Hz / 100%
 Speed adjusting range  1:100 (without PG)   1:1000 (with PG)
 Stable speed precision  ±0.2% (without PG)   ±0.02% (with PG)
 Torque controlling precision  ±5% (with PG)
 Overload capacity  G type model: 150% of rated current can last at most 60s,  180% of rated current can last at most 3s, P type model: 120% of rated current can last at most 60s,  150% of rated current can last at most 3s
 Improve of torque  automatic improve of torque; improve of torque by hand 0.1% - 30.0%
 V/F curve  Three methods: linear type, multi points type;  nth power V/F curve (1.2th power, 1.4th power, 1.6th power, 1.8th power, 2th power)
 V/F separte  2 methods: all separte and semi separte
 Acceleration / Deceleration curve  Linear type or S curve method of accleration / deceleration. Four types of accleration / deceleration time, accleration / deceleration time range is 0.0 - 6500.0 S
 DC brake  DC brake freuquency: 0.00Hz - max frequency. Brake time: 0.0S - 100.0S. Brake action current value: 0.0% - 100.0%
 Jog control  Jog frequency range: 0.00Hz - 50.00 Hz, jog accleration / deceleration time 0.0S - 6500.0S
 PLC multi stage speed operation  Can achieve at most 16 stage speed operation by built-on PLC or control terminals.
 Built-in PID  Can convenient achieve precedure control close loop control system
 Automatic voltage adjusting  When power grid voltage changes, can keep output voltage stable automatically.
 Control of losing speed from overvoltage and overcurrent  Limit automatically the current and voltage during operation, to prevent frquent tripping operation of overcurrent and over voltage.
 Quick limit of current function  Decrease overcurrent breakdown at biggest level, to protect inverter run normally
 Torque limit and control  "Navy" characteristic, limit torque automatically during operation, to prevent frquent tripping operation of overcurrent, close loop vector control can achieve torque control. 

It can drive a variety of motors:high-speed motor,electric spindle,variable frequency motor,AC servo motor,various synchronous motors and ordinary asynchronous motors. Use in elevator, lift, machine tools.
