- Built-in PID control can realize closed-loop control of various variables, and when it is constant, the inverter is in a resting state, thus realizing good energy-saving performance.
Multi-segment frequency control function: & segment speed control.
Adopt current closed-loop control, so as to realize inverter to motor current control, ensure reliable operation of inverter, and improve product reliability.
- Overload capacity: 150% of rated current for 60s for heavy load; 120% of rated current for 60s for light load,
- Carrier frequency: 0.5K~15.0kHz
Perfect various protection functions: overcurrent, overvoltage, undervoltage, overtemperature, phase loss, overload, power-on to motor ground detection and other protection functions standard RS48S communication.
