Incremental encoder specification
Never supply both incremental encoders using one supply cable!
 The connection cables for the incremental encoders must each be in a separate plastic-
sheathed cable as otherwise a cable break could cause an error that could remain
undetected.
 The power supply to the two incremental encoders must be independent. For this
purpose use the connection terminals provided, 16 and 17 as well as 20 and 21.
 Each incremental encoder output (for 0° or 90°) is only allowed to be connected to one
control input, e.g. C1/D1 or C2/D2.
Both incremental encoders must meet the following specifications:
 two-channel rotary encoder with 90° phase offset
 supply voltage: 24 V DC
 outputs: push/pull outputs
 enclosure rating IP 54 or better
 screened cable
 max. pulse frequency: 100 kHz
 min. number of pulses: 50 pulses per cm
You can procure suitable incremental encoders from SICK AG, tel.: +49 211/5301-250 or
at www.sick.com. Or contact your local SICK representative.
Control inputs
You can only connect the input signals to one safety laser scanner. Distributed connection
of the input signals to two safety laser scanners is not possible.
