Industrialized Design AC Inverter Drive Speed Controller Large
Torque With 485 Communication
ZF3000 series inverters are high performance open loop vector
inverter for controlling asynchronous AC induction motors and permanent magnet synchronous motors. Applying the leading international technology and DSP control system. The
product enhances its reliability to meet the requirement of environment adaptability, customized and industrialized design
with more optimized functions, more flexible application and more stable performance.
1. Compatible with various motors, can be widely used for driving
asynchronous motors and permanent magnet synchronous motors.
2. Excellent control performance in sensorless vector control mode.
a). Four-quadrant operation of the motor in sensorless vector
control mode . The torque ,current ,spinning speed and DC bus
voltage have quick response ,and the motor has stable operation.
b). 0.1 s acceleration/deceleration is available with rated motor
c). During forward and reverse running, the current and speed will
d). Quick and reliable braking can be get when deceleration with
3. Large torque at low speed stable operation under vector control
Start torque : 0.5Hz can get 150% torque ( sensorless vector control mode ).
0.0Hz can get 180% output torque (sensor vector control mode).
Application: it is easy can use in Medium and large wire-drawing machine, pipe
and cable processing, lifting equipment, rolling mill, lift
4. Excellent torque response time.
a).Torque response time less than 20ms in the sensorless vector
b).Torque response time less than 5 ms in the sensor vector control
c). Keep output torque stable and make motor running smoothing .
Application: It is easy can use winding/unwinding equipment, multi-point driver
,rolling mills ,printing machine and packaging machine, paper
5. Torque control and limit function.
Torque control is available in sensor vector control mode.
This protection function can limit the output torque make you
machine in safe condition all the time .Enhance the efficiency at
most don’t worry will cause machine damage .
Application: Fan/pump, the equipment whose operation shall be traced upon the
power recovery after instantaneous power failure .such as fan,
blower, rolling milling, pump.
6. Fast current limit function to make really tripless operation.
Special design fast current limiting algorithm, reduce over current
fault probability occur .realize on trip in fluctuation load heavy
