50 Operating Time UDINT R Incremented at power-up.
Subsequently, the value
increases by 1 every 6 minutes.
51 Offset Value DINT R The preset function shifts part of
the position value to the offset.
The offset value is automatically
stored in the device and can be
used for diagnostics.
Offset value = Preset Value -
Position Value
100 Position 64-Bit ULINT R See Table 4.8
101 Raw Position ULINT R Raw position value of the
encoder.
102 TMR 64-Bit ULINT RW See Table 4.9
103 Preset 64-Bit LINT RW See Table 4.9
104 Offset 64-Bit LINT R See attribute 51
105 Hysteresis Position SINT RW Size of the hysteresis for the
position value
Value range: 0...255
Default: 04h
106 Filter Position SINT RW Number of average values for
the position value.
Value range: 0...255
107 Gear Multiplier WORD RW The two parameters gear ratio
numerator and denominator can
be used to adjust the position
value to take into account an
existing gear.
-The total resolution for this
function is limited to 20 bits
(max. 1,048,576 steps).
-The revolution resolution has no
relevance for this function, the
16-bit raw resolution is always
used.
Example rotary table:
Gear encoder: 12 teeth
Driven rotary table: 250 teeth
One revolution of the rotary table
should be mapped to 100000
steps.
If the driven rotary table rotates
once, then the encoder shaft
