| Possible Causes |
|
|
|
|
|
|
Speed Error | • | Result of a motor speed that is greater than the commanded speed when using an |
|
| encoder for speed control. |
| • Improper encoder connection or setup information. | |
| • | Defective encoder. |
|
|
|
Overtorque | • | A torque requirement by the load in excess of the setting of parameter 0616 or |
|
| 0617 for a time longer than the setting of parameter 0618. |
| • The ASD is improperly matched to the application. | |
| • The load is obstructed. | |
|
|
|
Overvolt Accel | • | Motor running during restart. |
|
|
|
Overvolt Decel | • | Deceleration time is too short. |
| • DBR value is too high. | |
| • DBR required (DBR setup required). | |
| • Stall protection is disabled. | |
| • | |
| • | Input reactance required. |
|
|
|
Overvolt Run | • | Load fluctuations. |
| • | |
|
|
|
Positional Err | • | Operating in the Position Control mode and the resulting position exceeds the |
|
| limits of the Position Control setting. |
|
|
|
RAM Err | • | Internal RAM malfunction. |
|
|
|
ROM Err | • | Internal ROM malfunction. |
|
|
|
Sink/Source Error | • | Improperly positioned Sink/Source jumper on the control board or on an option |
|
| device. |
| • Sink/Source configuration of an option device is incorrect. | |
|
|
|
Type(form) Error | • | Firmware information (typeform) loaded into the Gate Driver board is |
|
| inconsistent with the device in which the firmware is being used. |
| • The Gate Driver board has been replaced. | |
| • The Gate Driver board is defective. | |
|
|
|
U Phase OC | • | Low impedance at the U lead of the ASD output. |
|
|
|
V Phase OC | • | Low impedance at the V lead of the ASD output. |
|
|
|
W Phase OC | • | Low impedance at the W lead of the ASD output. |
|
|
|
Note: The event that caused the Trip(s) must be corrected or must decrease to less than the threshold value required to cause the trip to allow for a Reset to be recognized. In the event of multiple active trips, the trip displayed will remain until all faults are corrected and all trips are cleared.
