Chapter 5 Function parameter
manner
Enable Quick Current Limiting function, which can minimize the overcurrent fault of
inverter , and ensure the uninterrupted operation of inverter. If the drive is in the state of
fast current limiting for a long period of time , the inverter may be damaged by overheating
and others, this case is not allowed, so the inverter will alarm fault with fault ID Err.40, it
indicates that the inverter exists overload and needs to be shut down.
Undervoltage
Fb.01
setting
Used to set the voltage value of inverter undervoltage fault with fault ID Err.09 , the
different voltage levels of inverter 100.0% corresponds to the different voltage points are as
follows:
Single-phase 220V or three-phase 220V: 200V three-phase 380V: 350V
Three-phase 480V: 450V three-phase 690V: 650V
Overvoltage
Fb.02
setting
The setting over voltage point of the software has no influence on the setting over
voltage point of the hardware.
The value of the voltage setted to the frequency inverter, different voltage level „s
factory defaults are as following:
Voltage level
Single phase
Three phase
Three phase
Three phase
Three phase
Remark: Meanwhile, the factory defaults are the upper llimit value of over voltage
protectation in frequency inverter. Only when Fb.02 setting value is smaller than all
voltage factory defaults, the new parameter setting takes effect. If it is higher than
factory defaults, factory defaults will be the standard value.
Deadband
Fb.03
compensation
selection
Generally do not need to modify this parameter, only when the special requirements to
the output voltage waveform quality is required or when the motor oscillation and other
abnormal happen, you need to try to switch to select a different mode of compensation.
The compensation mode 2 for high-power is recommended.
