U511 User’s Manual Appendix G
Version 1.1 Aerotech, Inc. G-7
G.4. UNIDEX 511 Software Setup
The U511 software needs to be configured for the RDP board. Parameters from the Motor
and Feedback page (Page 8) in the Setup menu, need to be updated to reflect the hardware
settings of the RDP board as shown in the following tables.
1. Set the “Position channel” parameter (x38) as shown in Table G-8.
Table G-8. Setting “Position channel” (x38) for the RDP Board
Axis “Position channel” for
RDP Board #1
“Position channel” for
RDP Board #2
1 9 (default) 13
2 10 (default) 14
3 11 (default) 15
4 12 (default) 16
If using an RDP board to incorporate a secondary feedback device, the same settings
would apply, but the parameter called “Velocity channel” (x39) would be changed.
Otherwise, the “Velocity channel” parameter should be zero.
2. Set the “Position setup code” parameter (x40) for the hardware resolution as
configured by RCN 1 through RCN 4. Refer to Table G-9.
Table G-9. Setting “Primary feedback setup code” (x40) for the RDP Board
Resolution Counts/Revolution “Primary feedback setup code”
16-14 bit dynamic resolution 65,536 5
16 bit 65,536 4
14 bit 16,384 3
12 bit 4096 2
10 bit 1024 1
Not used –– 0
If using an RDP board to incorporate a secondary feedback device, the same settings
would apply, but the parameter called “Velocity setup code” (x41) would be
changed. Otherwise, the “Velocity setup code” parameter should be zero.
3. Save the parameter changes and reinitialize the UNIDEX 511 to make them take
effect.
