RegisLtch0/1Stat
Indicates the control status of registration latch 0 and 1.
• Bit 0 “RL0 Armed” and bit 16 “RL1 Armed” indicates the registration latch is armed.
• Bit 1 “RL0 Found” and bit 17 “RL1 Found” indicates the registration event has triggered the latch.
• Rising edge of 'Arm request' will set the 'Armed' status bit.
• Rising edge of 'Disarm request' will clear the 'Armed' status bit.
239 RegisLtch1
Value
Displays the registration data of port 1. Indicates the position reference counter value latched by the external
strobes. The strobe signal used to trigger the latch is configurable by
[RegisLtch 0/1Cnfg].

Position
Displays the position feedback (accumulator) from encoder 1. The value changes by a value of four times (4x) the
Pulses Per Revolution (PPR) rating of the encoder for each full revolution of the encoder shaft. Used by the VPL to
close the position loop if position control is selected.
