AMC Master Source Select (32.001) can be set to a value between 2 and 11 to select a position feedback source as the master reference from the drive position feedback interface or from the position feedback interface in a position feedback category option module. It should be noted that the position includes the effect of the marker function of the position source. If the selected position feedback source does not exist (i.e. it is not present in the drive or option module, or the option module cannot provide position feedback) the source position will remain at zero.

If the AMC Master Source Select (32.001) is set to 0 the AMC Master Speed Reference (32.008) is used as the source and provides a position that changes at a constant rate against time. This allows profiles to be produced with a time base instead of a synchronous profile related to master position.

If the AMC Master Source Select (32.001) is set to 1 the AMC Master User Position Reference (32.009) is used as the source. This allows the master position to be provided by the user, or to be provided from a fieldbus interface.

AMC Master Invert (32.002) negates the delta position values that are accumulated by the master source integrator if AMC Absolute Mode Enable (31.002) = 0, or negates the absolute position written to the master source integrator if AMC Absolute Mode Enable (31.002) = 1.

The AMC Master Position (32.004) is the sum of the position in the master source integrator and the AMC Master Offset (32.003).

AMC Master Freeze Select (32.007) is used to select which freeze source associated with the master source should be used to provide the AMC Master Freeze Position (32.006). For example, if a position interface within the drive is being used as the master source then the F1 or F2 freeze source provided in the drive can be selected. During the sample after a freeze event occurs the AMC Master Position (32.004) at the point in time when the freeze event occurred is stored in the AMC Master Freeze Position (32.006)AMC Master Freeze Flag (32.010) can be used to determine when a freeze event has occurred and clear the master source freeze flag.

If an option module is being used as the master source then a freeze source in the option module can be selected. If a freeze source selected in an option module does not exist then the AMC Master Freeze Position (32.006) will remain at its present value.
