AUTO TUNING |
| The Auto Tune procedure is used to automatically measure and calculate certain |
|
| parameter values. Dynamic Brake Hardware is required to perform “Slip Freq Test” |
|
| and “Spd Cntrlr Calc” autotuning test. 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. |
| CALC Presets | Loads operating values into memory. These values are based on information |
|
| programmed into the Level 2 Output Limits and Motor Data parameter values. |
|
| CALC Presets must be run before Autotuning or manually tuning the drive. |
| CMD Offset Trim | This procedure trims out voltage offsets for the differential analog input at |
| CUR Loop COMP | Measures current response to pulses of one half the rated motor current. |
| Flux CUR Setting | Sets motor magnetizing current by running motor at near rated speed. |
| Feedback Tests | Checks the values for Encoder Lines per revolution and encoder alignment parameters |
|
| while the motor is running at near full rated speed. Test will automatically switch |
|
| encoder phasing to match motor rotational direction. |
| Slip FREQ Test | Calculates motor Slip Frequency during repeated motor accelerations. |
| SPD CNTRLR | Should be performed with the load coupled to the motor shaft. Sets the motor current to |
| CALC | acceleration ratio, Speed INT gain and Speed PROP 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 drive is loaded, adjust the PK |
|
| Current Limit parameter to a greater value and repeat this test. |
