AS5030.001 - "INC.AXI." - 2-channel INCREMENTAL READ OUT BOARD
Jumpers
A two-position jumper is installed: RESET and HOLD.
If the jumper is on RESET position, in case of system misbehaviour (WATCH DOG NOT-OK) all the outputs are set to their start
condition (outputs disabled = 0 Volt).
If the jumper is on HOLD position, or it is not installed, in case of system mishehaviour (WATCH DOG NOT-OK) all the outputs are left
in their current state.
Input / Output Words.
The Input/Output word address for each board (CPU excluded) depends on its position inside the rack. Addresses are here referred to
as “BASE” + a number representing the board internal offset. To find the value of “BASE” refer to the RHW.CFG configuration file
generated by the operating system during the autoconfiguration session and stored in the flash card. This file contains the address of
the I/O words for each board installed in your rack. The value of “BASE” is the value of the first Input or Output word in the board.
Number of Input Words: 6
Numerb of Output Words: 6
"Bit 0" is the least significant bit in the word, "Bit 15" is the most significant bit in the word.
Input Word ("BASE" + 0): Counter 1 real position (16 Bits)
Input Word ("BASE" + 1): Counter 2 real position (16 Bits)
Input Word ("BASE" + 2): Zero position for counter 1 (16 Bits) (significant only when a zero cycle has been successfully terminated)
Input Word ("BASE" + 3): Zero position for counter 2 (16 Bits) (significant only when a zero cycle has been successfully terminated)
Input Word ("BASE" + 4): Counter 1 state
Bit 0: 1 = zero micro in High State
0 = zero micro in Low State
Bit 1: 1 = zero cycle running
Bit 2: 1 = zero cycle successfully terminated
Bit 3: 1 = zero cycle alarm (state of the zero micro non consistent with the required 0 cycle)
Bit 4: 0 = encoder alarm
Bit 5: 0 = short circuit alarm on encoder supply
Bit 6: state of channel A
Bit 7: state of channel B
Bit 8: state of zer channel
Bit 9..15: non significant
N.B.: After reading this address, the existing alarms are reset, provided that the alarm condition has been eliminated.
