150% rated current for 1 minute, allowed once every 5 minutes (Heavy Duty mode) 110% rated current for 1 minute, allowed once every 5 minutes (Normal Duty mode)
Operating control characteristics
Frequency setting method
Keyboard number setting, analog quantity setting, pulse frequency setting, multi-stage speed running setting, simple PLC setting, PID setting, MODBUS RTU/Profibus/PROFINET communication setting, etc. Realize the combination of settings and the switching of setting channels.
Automatic voltage regulation function
When the grid voltage changes, it can automatically maintain the output voltage constant.
Fault protection function
Provide comprehensive fault protection functions: overcurrent, overvoltage, undervoltage, overheating, phase loss, overload, ground fault, motor stall, short circuit, etc.
Speed tracking restart function
Realize the smooth and impact-free startup of a rotating motor
