some warnings W1-W5: |
W2 - Počas odbudzovania klesol magn. tok na minimálnu hodnotu
W3 - Regulátor magnetického toku je v nasýtení (len vo vektorovom režime)
W4 - Regulátor momentu motora je v nasýtení (len vo vektorovom režime)
W5 - Regulátor rýchlosti je v nasýtení (len vo vektorovom režime)
- The converter reduces motor magnetic flux in order to achieve over-synchronous revolutions. | |
| 1 | W6 - Motor cooler has reached an increased temperature (over 75 °C). For VQFREM 400 005, 007, and 011 types, the module temperature is over 90 °C |
| 2 | W7 - The converter switches itself into scalar mode due to IRC/ARC failure. |
| 3 | W8 - Signalisation of reverse direction of IRC/ARC. |
| 4 | F7 - The time needed for motor field suppression has not expired yet (before subsequent start). |
| 5 | W12 - Process regulator is saturated. Converter frequency has reached its maximum value. |
| 6 | F9 - Position calibration initiated by 9.4.3 command, or calibration of IRC encoder on the synchronous motor. |
| 7 | F11 - The speed decreased to zero by activating a software terminal switch. |
| 8 | F8 - Dynamic deceleration was activated as a result of a sharp decrease in speed. |
| 9 | W16 - Sensored motor temperature has achieved nonpermissible value. |
