■ Function
To select vector control, automatic torque boost, or automatic energy-saving with <Pt: V/f Pattern>,
you must set motor parameters (auto-tuning).
There are four setting methods.
• Use <AU2: Torque boost macro> to set both <Pt> and <F400: Offline auto-tuning>.
• Set <Pt> and <F400> individually.
• Set <Pt> and <F400> individually. Perform an auto-tuning after calculating the motor parameter
automatically (available with motor not connected).
6. 23 Setting of motor parameters
WARNING
Prohibited
• Do not touch terminals or motor of the inverter while performing auto tuning.
Touching the terminals or motor while voltage is applied to the terminals and motor may result
in electric shock, even if the motor is stopped.
After setting offline auto-tuning (F400 = "2"), execute the auto tuning at first start of the inverter.
The auto tuning takes several seconds and the motor is stopped meanwhile, but voltage is
applied to the terminals and motor. The motor may also generate a sound during the auto
tuning, but this is not malfunction.
Mandatory
action
• Install circuit protection such as the mechanical brake in the crane.
If there is no sufficient circuit protection installed in the crane, insufficient motor torque while
auto tuning will cause the machine stalling/falling.
