PROGRAMMING IN THE NECESSARY PARAMETER VALUES BASED ON
CALCULATIONS YOU DO. REFER TO MANUALLY TUNING THE CONTROL
IN TROUBLESHOOTING SECTION 4 OF THIS MANUAL FOR INFORMATION
ON HOW TO DO THIS.
ALL AUTOTUNING PROCEDURES DESCRIBED BELOW SHOULD BE RUN IN
A NO-LOAD CONFIGURATION. THE LOAD SHOULD THEN BE COUPLED TO
THE MOTOR AND THE LAST TEST RERUN WITH THE MOTOR LOADED.
Calc Presets
- This procedure loads into memory the Factory preset values for parameters that are
not required to be loaded by the customer but are needed to run these tests. This test must always
be run.
Cmd Offset Trim
- This is the second autotuning test. It trims out any voltage offsets on the
differential input command at main control board terminals J1-4 and J1-5. It does not trim the
analog pot input at terminals J1-1, J1-2 and J1-3.
Cur Loop Comp
- This is the third autotuning test. This procedure measures current response to
commanded pulses of one-half the rated motor current.
Resolver Align
- This fourth auto-tuning test 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
then proceeds to check and re-adjust if necessary, the factory setting of the resolver.
SPD Cntrlr Calc
- This last autotuning test. If possible, it should be performed with the load
coupled to the drive. This procedure accelerates the motor to measure the current to acceleration
ratio. It also adjusts Speed Controller Integral Gain and Speed Controller Differential Gain. If this
autotuning procedure is done with no load, it will generally set the Speed Controller Integral Gain too
high for high inertia motors and loads if the Current Limit parameter is set too low. If the control is
too responsive when the drive is loaded, set the Current Limit to the proper higher value and rerun
this procedure.
