Voltage Frequency

Character

Adjust pressure/frequency ratio according to motor parameter and

unique algorithm

Current and

Voltage Restrain

Current closed-loop control, free from current impact, perfect

restrain function of overcurrent and overvoltage

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

Typical function

Multi-velocity and

Traverse Operation

7-segment programmable multi-velocity control, multiple operating modes are

optional.

Built-in PID controller (able to preset frequency). Standard configuration RS485

communication function, multiple communication protocol for choice, synchronizing

control function.
