VB5N series inverter
72
P5.06=1, Auto current limiting function is enabled when constant speed running;
In auto current limiting process, the inverter output frequency may change; therefore, if the inverter output frequency is
required to be stable, this function is not recommended.
waiting time of restart after power off
P5.07 = 0, invalid
P5.07 = 1, restart after power off
If instantaneous power off (LED shows E-11) occurs when inverter is running, after repowering, it will detect speed auto-
matically and then restart after the waiting time (P5.08). During the waiting time, the inverter will not start even you input
running command. If input stop command, the inverter will release the speed checking and restart status.
Interval of auto reset fault
When the inverter is in running process, it may has fault and stop output by accident for overload fluctuating.To avoid the
pause of the device, you can use auto fault reset function. In the reseting process, inverter will restart after auto-checking
the speed. If the inverter can not reset successfully in auto reset fault times, fault protection will be enabled and output will
be stop. This function will be OFF when auto reset times is 0.
Note: (1) When use this function, make sure inverter has no substantiality fault.
(2) This function is invalid for the fault caused by overload and overheats.

4-2-8. Close-loop control parameters (Group P7)
Analog feedback control system:
Pressure value is input in VI, and feedback value (4~20mA) of pressure sensor input to inverter terminal CI then pass
through the internal PI adjustor to form analog close-loop control system, as shown in Fig4-32.
