Hitachi WJ200 - AUTO-SPEED 90 HZ FUNCTION; SETTING THE AUTO-SPEED ACTIVATION VALUE

AUTO-SPEED 90HZ FUNCTION
The auto-speed function will allow the VFD to increase the high speed to up to 90Hz when there is an empty hook or a light load.
You can set this function for automatic or for input activation. The auto-speed function is not available when using 0-10V/4-20mA
speed control methods, when micro-speed is active, and or when in tandem mode.
HOW IT WORKS – When the hoist is commanded in the forward/up direction and the frequency reaches the set high speed
frequency, the VFD will check to see if the load monitor value is less than the auto-speed activation value and allow the frequency to
increase to the auto-speed frequency.
Use the charts below to properly configure the auto-speed function. If you don’t want Auto-Speed to activate unless there is an
input, you can configure digital input 6 or digital input 7 for the Auto-Speed enable command.

SETTING THE AUTO-SPEED ACTIVATION VALUE
Step
Instruction
1
Attached 30% rated load to the hook block and lift the load just off the ground.
*NOTE – 30% should be the max load for 90 Hz & 60% should be the max load for 75 Hz
2
Navigate to VFD parameter d027. This will display the load value that will be used to set the auto-speed activation
level.
3
Using the pushbutton or radio, command the hoist in the up/forward direction with high speed and record the value
of VFD parameter d027 while the load is operating at the high-speed frequency.
4
Navigate to VFD parameter P111 and set the value to the value recorded from d027 + 3%.
(example d027 = 37, set P111 = 40)
5
Verify the auto-speed function works by lifting the same load at high speed. If the auto-speed function is configured
for automatic then you should see the speed increase to 90hz, if you are using the input activation function then
make sure the input is active and you should see the speed increase to 90hz
