|
Automatic current limiting protection |
The output current is automatically limited to prevent heavy load overcurrent fault, and the heavy load has the performance of over-current speed limit of excavator |
|
|
Input and output phase loss protection |
Automatic detection and alarm function of output phase loss |
|
|
Process PID setting and feedback loss detection |
Process PID automatically identifies whether the given and feedback are lost, and the loss alarm function |
|
|
Output short circuit protection |
Effective protection function of output short circuit to ground |
|
|
