Three ways: 1.the linear torque characteristic curve

2. the square torque characteristic curve 3.  V / F curve set by the user

starting torque: 100% Rated torque at 5.0Hz

 (VF control) 150% rated torque at 1.0Hz (vector control)

The whole current closed-loop control,

completely avoid current impact,

 with perfect overflow pressure suppression function

Especially for users with low grid voltage and frequent grid voltage fluctuations,

the system can maintain the maximum possible operating time even within the allowable voltage range

7-segment programmable multi segment speed control,

 and multiple operation modes are optional

Built-in PID controller (pre-set frequency). Standard configuration

of RS485 communication function, a variety

of communication protocols are optional,

with linkage synchronization control function

According to the need, dynamic pressure, static pressure

and unstable pressure can be selected to obtain the most stable operation effect

The energy braking starting voltage, return

 voltage and energy braking rate can be adjusted continuously

Start frequency of shutdown DC brake: 0.00~

[F0.05] upper limit frequency Brake time: 0.0~30.0s;

 Brake current: 0.0%~50.0% rated voltage of the motor

Upper and lower limit frequency setting, frequency jump operation,

 reverse operation limit, turn frequency compensation,

 RS485 communication, frequency increasing,

decreasing control, fault self-recovery operation, etc

Record the output frequency, set frequency, output current, output voltage,

DC voltage, and module temperature of the latest fault

Over current, over voltage, under voltage, module fault,

electronic thermal relay, overheating, short circuit, internal memory fault, etc
