When Yaskawa Drive Show “bb”
How to solve it?
Most of the time, the rason is: the driver have no 24v supply.
So please check:
1, the wire from 24 power to driver. is it loose ?
2, the 24 power, is it damage?
3, if the 24v power and the wire is ok, so now we need check the driver, it is maybe damage.
