235 RegisLtch0 Value
Displays the registration data of port 0. Indicates the position reference counter value latched
by the external strobes. The strobe signal used to trigger the latch is configurable by
Par 236
[RegisLtch 0/1 Cnfg].
Default:
Min/Max: 0
-/+2147483648 RW 32-bit
Integer
236 RegisLtch 0/1Cnfg
Configures the registration latch at port 0 or port 1 to be used with Encoder 0 or Encoder 1, respectively.
•
Bit 0 “RL0 Encoder 1” selects the encoder for the input source of latched data. Setting bit 0 selects encoder 1, resetting the bit to zero selects encoder 0.
•
Bits 1 “RL0 TrgSrc0” and 2 “RL0 TrgSrc1” select the trigger source (see Table 236A: Encoder0 Trigger Source Settings ).
•
Bits 3 “RL0 TrgEdge0”, 4 “RL0 TrgEdge1”, 19 “RL1 TrgEdge0” and 20 “RL1 TrgEdge1” select which edges signal the position (see Table 236C: Edge Selection
Settings ).
•
Bits 5 “RL0 Dir Rev”, 6 “RL0 Dir Fwd”, 21 “RL1 Dir Rev” and 22 “RL1 Dir Fwd” set the direction of position capture (see Table 236D: Trigger Direction Settings ).
•
Bits 8 “SL DI Filt 0”, 9 “SL DI Filt 1”, 10 “SL DI Filt 2”, and 11 “SL DI Filt 3” configure a filter for the digital input 1 and 2 (see Table 236E: Filter Settings ). The filter
requires the input signal to be stable for the specified time period. Input transitions within the filter time setting will be ignored. Bits 8-11 add 100ns filter per
stage to external trigger.
•
17 “RL1 TrgSrc0” and 18 “RL1 TrgSrc1” select the trigger source (see Table 236B: Encoder1 Trigger Source Settings ).
•
Bit 0 &16 - off = Enc0 input to latch, on = Enc1 input to latch.
No.
