V/F Control

V/F Curve (voltage frequency character)

Reference    frequency         setting         5~600     Hz, multipoint   V/F   curve   setting,   or   fixed   curve   of constant   torque,   low   decreasing    torque   1,   low decreasing torque 2, square torque

Torque Compensation

Manual setting: 0.0~30% of rated output
Automatic    compensation:    according     to output    current    and  motor parameter

Automatic
Current-limiting  and Voltage-limiting

During acceleration, deceleration or steady running, detect   automatically   the   current   and   voltage   of motor stator, and  control it within bounds based on unique algorithm, minimize  fault-trip chance

Senseless Vector Control

Voltage Frequency

Adjust pressure/frequency ratio according to motor parameter   and unique algorithm

Torque Character

Starting torque:
3.0 Hz 150% rated torque (VF control)
0.5 Hz 180% rated torque (SVC, FVC)
0.05 Hz 180% rated torque (VC)
Operating speed precision in steady state:    ≤±
0.5% rated  synchronous speed
Torque response:    ≤50ms VC, SVC, FVC    ≤20ms

Motor Parameter Self-measureme nt

Being able to  detect parameter automatically under static   state    and   dynamic   state   of   motor,   thus guarantee an optimum  control.

Current and Voltage Restrain

Current closed-loop control, free from current impact, perfect restrain function of overcurrent and overvoltage

Undervoltage Restrain during

Specially for users  with a  low or  unsteady voltage power grid: even  lower than the  allowable   voltage  range,  the  system  can  maintain  the  longest  possible operating  time  based  on  its   unique  algorithm and  residual energy  allocation
