Hi Res0 TP Sel
Selects data displayed by Par 262 [Hi Res0 TP Data].
• H0 Edge Time - Latency counter value, not used for Hi-Resolution Feedback Option.
• H0 dEdge - Change in edge counts for one 500 microsecond update. At constant
speed, this value should be constant.
• H0 dTime - Change in update time. This value should be constant, 500 microseconds.
• H0 EPR - This value should be 1,048,576 counts per revolution - this is a constant
value.
• H0 dTheta - This is a scaled value of option 2.
• Ho Delta2Err - Derivative of option 2.

Reslvr0 Config
Configures options for the resolver option card at port 0.
• Setting bit 0 [Cable Tune] enables the cable tuning test, resetting the bit to zero disables the test.
• Bits 2 [Resolution 0] and 3 [Resolution 1] select the feedback resolution (see
Table 266A: Resolution Settings
). This determines the number of significant bits
that are calculated in the value of parameter 250 [FB Opt0 Posit]. It does not affect the number of counts created per resolver revolution (see
Resolution Setting and Least Significant Bits Used
). Also, the resolution sets a limit on the maximum tracking speed (see
).
• Setting bit 4 [Energize] energizes the resolver, resetting the bit to zero de-energizes the resolver.
• Bit 5 [Resolver Dir] determines the counting direction. If clear, the 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 12 [SmplRate bt0] through 15 [SmplRate bt3] configure the sample interval for measuring speed (See
Table 266D: Encoder Sample Interval
). Increasing
the encoder sample interval improves speed measurement near zero speed. Decreasing allows the speed control regulator to perform with high gains at
high speeds.
