Description
The Auto Tune procedure is used to automatically measure and calculate certain
parameter values. Occasionally, the Auto Tune procedure cannot be run due to
various circumstances such as the load cannot be uncoupled from the motor. The
control can be manually tuned by entering the parameter values based on
calculations you have made. Refer to "Manually Tuning the Control" in the
Troubleshooting section of this manual.
This procedure loads preset values into memory that are required to perform Auto Tune.
Always run CALC Presets as the first step of Auto Tune.
This procedure trims offset voltage at the differential analog input at J1A-4 and J1A-5.
Measures current response while running motor at one half the rated motor current.
This procedure checks the electrical alignment of the resolver with respect to the motor
stator. This test locks the motor rotor into a reference position and proceeds to check
are re-adjust if necessary.
Should be performed with the load coupled to the motor shaft. Sets the motor current to
acceleration ratio, Integral gain and Differential gain values. If done under no load,
the Integral gain will be too large for high inertia loads if the PK Current Limit is set too
low. If the control is too responsive when the motor is loaded, adjust the PK Current
Limit parameter to a greater value and repeat this test.
