Automatic bus voltage control to prevent overvoltage faults caused by large inertia load deceleration and power generation
Automatic current limiting protection
The output current is automatically limited to prevent heavy load overcurrent faults, and the heavy load has the overcurrent speed limiting performance of the excavator
Input and output phase loss protection
Output phase loss automatic detection and alarm function
Process PID given, feedback loss detection
Process PID automatically recognizes whether the given and feedback are lost, and the loss of alarm function
Output short-circuit protection to ground
Effective protection function of output short circuit to ground
Output phase-to-phase short-circuit protection
Output phase-to-phase short circuit effective protection function
Module overheating protection
When the load is too heavy, the fan is damaged or the cooling air duct is blocked, real-time monitoring of the module temperature and hot spot protection
Fan follow-up start with temperature control
The fan only rotates when the inverter is running, and the fan will stop after a delay when the temperature is too high when the inverter is stopped.
