The counter counts up to the “Counter reload value”, or
the “Counter reload value” (
8001:02 [ } 124] ) is loaded
in the event of an underflow
Example 360° encoder with set bit:
Moves in positive direction via Counter reload value
[ } 124] : Reset counter value to 0.
Moves in negative direction less than 0: Reset counter
value to
Counter reload value [ } 124] .
BOOLEAN RW 0x00 (0

122]
Activates input “C” for resetting the counter.
Example 360° encoder with set bit:
Moves in positive direction (signal at input “C”): Reset
counter value to 0
Moves in negative direction (signal at input “C”): under-
flow with FFFF, FFFE etc.)
