Configuration example 2: Distance sensor "DME5000-111" by SICK
Coding: Gray code with 25 bits of data word length
(Bit 0 = status bit in binary format, bit 1 ...24 = position, resolution 1 bit = 0.1 mm)
In "
", the feed constant and the gearbox factors for motors and position
encoders must be set as follows:
• The position encoder gearbox factor must be set to 1:1.
• When the motor gearbox factor is set to 1:1, the path covered at one motor revolution has to be
entered as feed constant in
in [units].
• In case of a different motor gearbox factor, the path covered at one defined "drive roll"
revolution has to be entered as feed constant in
in [units].
• The feed of the mechanics entered in
is displayed with 65536 increments.

* As the encoder data word in this example contains only one status bit, the evaluation can be deactivated
completely by entering the value "32" in
and
. Thus, the status bit outputs bState2 and bState3
of the
always have the value "0".
