SSI 021 S-DIAS SAFETY SSI ABSOLUTE ENCODER 10 Installing the Encoder Line and encoder errors are diagnosed using, among other things, the measurement of the encoder currents. For this purpose, the preset values for measuring current must be defined in the system. The current limits are defined in the automatic system automatically, so the user does not have to predefine or configure any additional parameters.
S-DIAS SAFETY SSI ABSOLUTE ENCODER SSI 021 11 Important Notes for Two-channel Application When using the SNC 021 module in compliance with SIL 3 according to EN 62061 and PL e, Cat. 4 according to EN ISO 13849-1, it must be taken into consideration that for 2-channel application, a part of the possible wiring errors can only be detected by comparing the measurement results of both encoders in the Safety application of the Safe CPU.
