1, Load feature
(1)  With big fluctuation.
(2)  Lots of dusts in the operation sites.

2,  Requests for AC Drives (VFD)
 (1) Soft start the motor, reduce the surge current, protect the motor and conveyer.
 (2) Big output torque at low frequency, it should run smoothly during working.
 (3) Motor speed can be adjusted by external potentiometer.
 (4) Running current can be monitored timely.
 (5) While the failures happen, the AC drive can output alarm or stop.
