application fields:
Pump fan, high-speed compressor, reciprocating compressor, wind tunnel air blower, the blast furnace blower, conveyor, extrusion machine, grinding machine, mine hoist, testbed etc
advanced inductive and non-inductive vector control strategy and function of automatic indentify parameter
Meet the master-slave control, zero speed hovering and other specific requirements
vector control and optional VVVFcontrol method 
Flexible configuration of VF curve several node setting
PID adjustor inside for user adjusting pressure flow conviniently
Pump of wind fan start smoothly and with no impact
start directly under the condion that motor is rotating for realizing start of rotating motor smoothly and with no impact
abundant control and operation protection function
many machine master-slave control function
water cooling heat dissipation,compact structure,high efficiency
The improved structure without filter is adopted in fourth quadrant power unit,can realize energy feedback of hoist conveniently,compact and reliable
