In the Mori maintenance manual tells whats mean, last year I change this fuji spindle driver instead a yaskawa F7 and I use that manual. I donīt remember well and I am in the country now. I donīt have the manuals with me. I think if you you look the connection of the driver there is a 88l wire or signal. Check and tell me maybe this refresh my memory.
Wyhen i put the F7 I have to change the motor too.
