1, Load feature
  (1)  During washing processing, the running frequency is around 10Hz.
  (2)  Heavy load at low frequency.
  (3)  Forward / reverse running are switched frequently.
  (4)  Big surge current.
  (5)  During spinning-dry processing, the running frequency is as high as 130Hz or higher than 130Hz.
  (6)  It always works at high humidity and high temperature conditions.

2,  Requests for frequency inverters (VFD)
  (1)  Output high torque at low frequency.
  (2)  Big capacity of over current and over load.
  (3)  It should run stably at high speed.

  4, Notices
(1)  The corresponding relationship between multi-step speed and wash process should be correct; each step speed should be
       adjusted base on real requests.
(2)  Because of the industrial washing machine sometimes will work at overload condition, the power of VFD should be selected
       one size higher usually.
(3)  The machine must be grounded reliably, pay attention to moisture-proof measures, the system must be maintained regularly.
