digital outputs in module groups 2 and 3 of rack 2. We use these outputs
to display the position, following error, and diagnostic codes for axis 2.
Rungs 7
thru 60
Rungs 7 thru 60 use discrete inputs to individually control bits of control
words 1 and 2 for each axis in the command block. You would not need a
rung to control bit 16 (tachometer calibrate) of axis control word 2,
because you only need to turn on this bit when you calibrate the
tachometer input. Also, you would not use rungs to control bits 17, 16,
15, and 14 (control word 1 ID) of axis control word 2, because you must
always have them set to the binary value 1100.
Rung 61
Rung 61 performs no logical function in the program. However, this rung
lets you display and enter values for all three moveset blocks for axis 1.
You can display all three blocks at the same time on the industrial
terminal by using its display function.
Rung 62
Rung 62 performs no logical function in the program. However, this rung
lets you display the parameter, command, and status block and enter
values for the parameter and command block. You can display all three
blocks at the same time on the industrial terminal by using its display
function.
Rung 63
Rung 63 performs no logical function in the program. However, this rung
lets you display and enter values for the moveset block for axis 2. You
can display the block on the industrial terminal by using its display
function.
Rungs 64
and 65
Rungs 64 and 65 are block transfer timeout rungs. If a block transfer is
not completed within three seconds, bit 15 of TON 0051 goes on, causing
output 02400 to be latched on. This output can be used to turn on a
warning
device.
