Programming and Parameters
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
). 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.
237 RegisLtch0/1
Ctrl
Configures the control for registration latch 0 and 1.
• Set bit 0 “RL0 Arm Req” and bit 16 “RL1 Arm Req” to arm the registration logic for the next trigger event. The particular latch will be armed and ready to be strobed on the next occurrence of the
trigger input.
• Set bit 1 “RL0 DisarmReq” and bit 17 “RL1 DisarmReq” to disarm the registration logic for next trigger event.
After the registration is captured, bit 0 “RL0 Arm Req” and bit 16 “RL1 Arm Req” automatically resets back to 0 after found. Bit 1 “RL0 DisarmReq” and bit 17 “RL1 DisarmReq” are only needed to
disarm a registration latch that has not been found yet. Setting bits 1 and 17 will clear the bits 0 and 6. Setting bits 0 and 6 sets bits 0 “RL0 Armed” and bit 16 “RL1 Armed” and clears bits 1 “RL0
Found” and bit 17 “RL1 Found” of
[RegisLtch0/1Stat].
