Creating Custom Motor Files

D-3

The text string translates the table ID into a real motor model number
for display. For example, the user can select the text string “H-4030-P-
H” rather than entering the table ID #23. Figure D.1 defines the text
string format of Allen-Bradley motors.

Motor Phasing

The phasing of the back-EMF and Hall feedback signals must be
verified before a custom motor file can be created. Allen-Bradley
motors use back-EMF and Hall feedback signals phased as shown in
Figure D.2. Motors not manufactured by Allen-Bradley require the
back-EMF and Hall feedback signals be phased to match those of
Allen-Bradley motors. Often this requires swapping of the R- and T-
phase control signals with each other, as well as swapping the Hall A,
Hall B, and Hall C signals with each other.

Back-EMF and Hall Signals

Figure D.2(a) shows the required phasing of the line-to-line back-
EMF signals and Figure D.2(b) shows the proper phasing of the Hall
feedback signals, when the motor is rotating clockwise (CW) as seen
looking at the motor shaft from the load
.

The relationship of the Hall signals to the back-EMF signals is not
important at this stage. However, the sequencing of the back-EMF
signals must conform to Figure D.2(a), and the sequencing of the Hall
feedback signals must conform to Figure D.2(b).
