6.3.3.4 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 " Machine parameters ", 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 C01204 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 C01204 in [units].
• The feed of the mechanics entered in C01204 is displayed with 65536 increments.
Parameter Info Setting for example 2
C00426/1 SSI encoder: Data word length 25
C00426/2 SSI encoder: Bits SingleTurn 24
C00426/3 SSI encoder: Start bit Singleturn 1
C00426/4 SSI encoder: Bits Multiturn 0
C00426/5 SSI encoder: Start bit Multiturn 0
C00426/6 SSI encoder: Status bit 1 0
C00426/7 SSI encoder: Shift of raw value 7
C00426/8 SSI encoder: Status bit 2 0 (32)*
C00426/9 SSI encoder: Status bit 3 0 (32)*
C00428 SSI encoder: Coding 2: Position Gray
C01110 LS_MultiEncoder: Solid measure 1: linearly unipolar
* 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 C00426/8 and C00426/9 . Thus, the status bit outputs bState2 and bState3
of the LS_MultiEncoder always have the value "0".
