Defining Parameters of the FM 453
Zero Reference
Figure 5-5 shows the relationship between the zero reference mark in your
Mark
application and the relevant machine data.
> 1 (absolute encoder)
MD10 (encoder type)
= 0 (servo motor)
MD61(control mode)
= 0
MD37.24 (control signal -
BMN active)

Zero Reference Mark Selection
Note
In the case of the zero mark variants that are marked with a grey back-
ground, the "Rotation monitoring" function can be used.
