Need Help!- Difference between A06B-0158-B077 #7008 and A06B-0158-B075 #7008 ??

[Rockey]

Hi,

Hopefully this is an easy question. I remember seeing a part# designation from Fanuc but can't seem to find it anywhere now. I have a potential customer with an A06B-0158-B077 #7008 that wants to know if my A06B-0158-B075 #will be interchangable. Thanks in advance!

The motor should be the same, the difference is in the encoders, the B077 is I64 Differential, the B075 is A64 absolute.
If it is just the motor itself that is the problem, the encoders may be interchangeable.

you can always replace a motor with B077 (Incremental) with a B075 (Absolute), if ALL the other motor PN digits are the same. There no difference in connections, parameters, etc to maintian the standard operation.

The B075 provides the additional capability of memorizing position while power is off, provided that certain other parameters are set up and that a battery source is provided.
