NOTE – The E-stop / maximum upper limit will retain function to prevent over-travel into the frame. The VFD will automatically control
the AL relay output for brake release command during auto-tuning.
IMPORTANT! – If a secondary brake is connected make sure the corresponding terminal function has been assigned to 62:LOG1
before starting the auto-tune.
Step
Instruction
1
Remove all attached loads from the hook. If you plan to do a rotational auto-tune remove the wire rope from the
drum.
2
Navigate to VFD parameter HA-01 and select 01: No Rotation for a static tune or 02: Rotation for a rotational tune.
Save the selection
3
On the VFD press the GREEN RUN button once and the auto-tune process will start. If there is an issue or you wish to
stop the auto-tune process, then press the RED STOP/RESET button.
4
Once the auto-tune process is complete the display with show the results of the R1,R2,L for a static tune or
R1,R2,L,IO,J for a rotational tune. The auto-tune data will automatically be applied to the motor constant parameters.
5
The auto-tune process is now complete.
