function

Overload capacity

G:150% 60s 200% 2s ; p:120% 60s 150% 1s

Instantaneous  overcurrent/

short circuit protection

Automatically cut off output when the rated output current exceeds 200%

Overvoltage/secondary voltage protection

When the DC voltage of the bus is too low (360V) or too high (800V), the motor stops freely (except during braking)

Phase loss protection

When there is a phase loss at the input or output end, the motor stops freely

Overheat protection

When the radiator temperature is ≥85 ℃, the motor stops freely; The temperature protection threshold can be freely set according to the ambient temperature

motor protection

Analog input can be connected to temperature sensor inputs (PT100, PT000) to achieve motor overheating protection

Stall protection

Using current sensors to detect stall prevention duning acceleration and daceleraion, and stall prevention during operation (action current can be set)

ground protection

Using current sensors for detection

Instant stop

By compensting for vatlage reducion though load feedback energy, the frequecy conveter can maintain continuous operation for a short petiod of time
