Operating speed precision in steady state: ≤±0.5% rated
synchronous speed
Torque response: ≤50ms VC, SVC, FVC ≤20ms
Motor
Parameter
Self-measurement
Being able to detect parameter automatically under static
state and dynamic state of motor, thus guarantee an optimum
control.

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

during
Running
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 strategy
