(x1)
Defines the system behaviour of the DP_Controller ASIC. – Not adjustable in the con-
fig. tool.
(m1)
Manufacturer-specific function. – Not defined in the encoder profile.
(m2)
Value has no meaning for
ATM60-P/ATM90-P
rotary encoders. Function is always en-
abled.
For linear encoders of the
KHK53-P
type, the function is optionally adjustable (default
setting = enabled (1)) – see following pages.
(p1)
For the
ATM90-P
, the functions of bit 1 and bit 2 are interchanged.
(p2)
Device-dependent – see below.
8.3.3 Operating Mode
8.3.3.1 Code Sequence
Definition of the counting direction for the position value:
0
CW
clockwise ascending
Default setting
1
CCW
counter-clockwise
ascending
Setting per telegram is only possible if setting by hardware via DIP switch S1-(8)
is
OFF
.
The view to determine the counting direction is device-dependent:
For the ATM90-P: looking at the baseplate; for the ATM60-P: looking at the shaft; and for the
KHK53-P: beginning from the first measuring element (X0001).
