control method:
1.)vf control(start torque: 0.50hz 180%,speed adjustable rang: 0.111111111, speed stabilizing precision:±0.5%)
2.)senseless vector control:( start torque: 0.25hz 180%, speed adjustable rang : 0.180555556, speed stabilizing precision: ±0.2%)
3.sensor close loop vector control(start torque: 0.00hz 180%, speed adjustable rang : 1.430555556, speed stabilizing precision: ±0.02%)
4)waveform produce methods: asynchronous space vector pwm, n-class sub-synchronous space vector pwm, two-phase optimization of space vector pwm.
5)auto torque boost function:achieve low frequency (1hz) and high output torque control under v.f control mode.
6)accelerate decelerate control:sub-set s curve acceleration and deceleration mode, maximum acceleration and deceleration time is 3200 days
7)long running time control: 16 segments speed run, maximum running time is 3200 days
8)frequency setting accuracy: digit: 0.01hz(below 300hz), 0.1hz(above 300hz); analogue:1% of maximum frequency
9)frequency accuracy:speed control tolerance 0.01%(25°c±10°c).
10)vf curve mode: linear, 1.2 times the power, 1.7 times the power, 2 times power, user-set 8 v f curve.

11)over load capability
g s type: 150% rated current -1 minute, rated current 200% -0.1 second;
f: rated current 120% -1 minute 150% of rated current -0.1 second;
z m t type: rated current 180% -1 minute 250% rated current -0.1 second;
12)slip compensation: v f control can automatically compensate for deterioration.
