Programming and Parameters Chapter 2
268 Resolver0 Cnfg
Configures options for the resolver option card port 0.
• Setting bit 0 “Cable Tune” enables the cable tuning test, resetting the bit to zero disables the test. Refer to the section on Resolver Cable Tuning Tests in publication PFLEX-RM003, Reference
Manual - PowerFlex 700S Drives with Phase II Control for more information.
• Bit 1 “Tune Param” has been disabled.
• Bits 2 “Resolution 0” and 3 “Resolution 1” select the resolver resolution (see
Table 268A: Resolution Settings ). This determines the number of significant bits that are calculated in the value of Par
250 [FB Opt0 Posit]. It does not affect the number of counts created per resolver revolution (see Table 268B: Resolution and Least Significant Bits Used ). Also, the resolution sets a limit on the
maximum tracking speed (see Table 268C: Resolution and Resolver Tracking Speed ).
• Setting bit 4 “Energize” energizes the resolver, resetting the bit to zero de-energizes the resolver.
• Bit 5 “Resolver Dir” determines counting direction. If clear, direction is forward or up. If set, the direction is reverse or down.
• Bit 9 “Edge Time” configures the method of sampling used by the Velocity Position Loop (VPL). Setting the bit chooses "Edge to Edge" sampling, while resetting the bit to zero chooses "Simple
Difference" sampling. "Simple Difference" sampling calculates speed by examining the difference between pulse counts over a fixed sample time. "Edge to Edge" sampling adjusts the sample
time to synchronize with the position count updates from the daughter card - improving the accuracy of the speed calculation.
• Bits 10 “SmplRate bt0” through 12 “SmplRate bt2” configure the Finite Impulse Response (FIR) Filter (see Table 268D: FIR Filter Settings ). This setting reduces the effect of noisy feedback on the
system. Refer to the Speed/Position Feedback section of the PowerFlex® 700S with Phase II Control Reference Manual, publication PFLEX-RM003 for details.
Note: Bit 11 “SmplRate bt0” is set to 0 = False by default for firmware version 1.11 and bit 11 “SmplRate1” is set to 1 = True by default for firmware version 2.003.
269 Resolver0 Status
Indicates status of the resolver option card port 0.
• Bit 0 “-Cable Tune”
• Bit 1 “-Tune Result” indicates the tuning Parameter type. When set, it indicates the tuning is using the parameter database. When cleared, it indicates the tuning is using derived data.
• Bit 2 “-Mtr Turning” indicates that the motor is turning.
• Bit 4 “Energized” indicates the resolver is energized.
• Bit 8 “Open Wire” indicates a problem with the cable (open circuit).
• Bit 9 “Power Supply” indicates problem with the option card's power supply.
• Bit 10 “Diag Fail” indicates the option card has failed its power-up diagnostics.
