11.4 Zero load calibration sequence with motor toque
Power On
Enter password 0732.
Select the hoist.
Go to menu 3-1-1.
Move to the next section with the arrow up button.
Hang a test-load of less than 30% of the rated load of the hoist in
the hook. Typically this is an empty hook. Make sure the load
hangs freely and steady. Enter the value of the test load (in tons,
empty hook = “0.00t”).
Confirm the correct value with the ENT button.
The text “Up. Slow” appears on the display. Drive the hoist in slow
speed upwards until the next text appears
Drive the hoist in fast speed upwards until the next text appears.
Drive the hoist in slow speed downwards until the next text
appears
Drive the hoist in fast speed downwards until the next text
appears.
Run the calibration sequence according to the display instruction.
When the calibration is done, write down the load setup values of parameter group 3-2 in the
commissioning table.
11.5 Manual load calibration
Before starting the calibration, make sure you have a known test-load available of at least 80% and
maximum 130% of the nominal lifting capacity of the hoist
It is advisable to by-pass the overload protection during this calibration routine by setting the parameter
3-5 “OL protect” = OFF
The overload protection will automatically reset after 30 min. or after power off.
If the display shows more than the lifted load, continue with A.
If the display shows less than the lifted load, continue with B.
