How to lift Yaskawa inverter base blockade?
Unlock the base block of Yaskawa inverter:
1. If the Yaskawa inverter reported that the base blockade, we should first check the cause, parameter settings in strict accordance with the recommendations of professional engineers to set.
Note: the base blockade is to deal with ul or ce such a special application of security agencies, meaning that when the parking limit action after the base blockade even if the program can not malfunction, relative to the emergency stop loop more harsh, they will directly cut off the power power supply. In fact, it is a white protection function, if we are not difficult to find the analysis, when over-voltage or undercurrent, the panel will show BB alarm, BB is the base block, is the base blockade.
2. If you can not solve the problem, be sure to seek the help of professionals.
? 3. If the base of the frequency converter blocks the input signal. While the base blockade, the inverter power tube is all closed, this one is mainly to protect the power tube. So the external input signal once resolved, the base block is automatically removed.
