Start-Up 4 - 10

Auto-Tuning

Auto-Tuning the motor is required for optimum performance. Use the following flow chart to determine which one of the three
Auto-Tuning Mode Selections to use.

Figure 4.2 Auto-Tuning Selection Flow Chart

Note: Performing Auto-Tuning energizes the motor so that identification of key motor characteristics can be determined. Out-
put filters may affect the accurancy of the measured characteristics and/or result in drive damage. Therefore, it may be nece-
sary to remove the filters completely prior to executing the following tuning procedure. Consult the factory with questions
regarding filter compatibility.

Standard Tuning

Always use Standard Tuning (rotational) when operating in Open Loop Vector or Flux Vector (A1-02 = 2 or 3) and it is possi-
ble to run the motor uncoupled from the load.

1.

Select the Auto-Tuning Menu. Then, select “Standard Tuning” in the “Tuning Mode Sel” parameter (T1-01 = 0).

2.

Set the motor output power (T1-02), motor rated voltage (T1-03), motor rated current (T1-04), motor base frequency
(T1-05), number of motor poles (T1-06), motor rated speed (T1-07) obtained from the motor nameplate information.
If the Control Method is Flux Vector (A1-02 = 3), be sure to set the encoder pulses per revolution (PPR) (T1-08).
After entering all of the motor parameters press the UP key to display “0Hz/ 0.00A Tuning Ready?”.
