This appendix lists the features that were added to the
module in versions 57C422A and 57C422B.
Note that some modules which do not have 57C422A on the
faceplate may also support the features implemented in
57C422A. If the "B/M" designation on the side of the module
is "B/M 57422-1 ", the module will function as a 57C422A
regardless of whether the faceplate reads 57C422 or
57C422A.
M/N 57C422A
1. Interrupts (registers 64, 68, 69, 104, 105, 4095)*
2. Current velocity status update period (register 83)
3. Current velocity in double precision integer (registers 78
and 79). (Note that register 79 is now the lower order 16
bits.)
4. S-curve profile (register 65 bit 6)
5. Shortest path rotary move (register 65 bit 10)
6. Automatic backlash compensation (register 65 bit 11)
7. Backlash compensation (registers 39 and 40)
8. Passive home on marker pulse for feedback encoder
(register 67 bit 4)
9. Passive home on marker pulse for gearing encoder
(register 67 bit 5)
10. Relative change in feedback position (register 67 bit 6)
11. Expanded gearing modes (register 38 bits 0 and 1)
12. Gear ratio as two integers (register 38 bit 2)
13. Ramp velocity control during gearing changes (register
38 bit 3)
14. Position cam (registers 125 - 127, register 130 bit 8)
