- Page 3 SNC 021 S-DIAS Safety SNC Incremental Encoder SNC 021 The S-DIAS Safety SNC incremental encoder module SNC 021 provides the values of two incremental encoders to the Safety CPU as well as the non-Safe CPU (standard PLC). The two-channel safety function "monitors" the increments in the incremental encoder interfaces and processes the so-called Safety core in two micro controllers with cross-communication.

Page 31: Encoder Configuration
S-DIAS SAFETY SNC INCREMENTAL ENCODER SNC 021 10 Encoder Configuration The maximum encoder frequency is defined with 750 kHz (at 1x edge analysis). This corresponds to a maximum counter frequency or 1.5 MHz (at 4x edge analysis). When selecting the encoder to install, this must be taken into consideration accordingly. - Page 32 SNC 021 S-DIAS SAFETY SNC INCREMENTAL ENCODER Legend: … highest permissible speed in revolutions/sec or revolutions/min. … maximum encoder frequency of 750 kHz … encoder resolution according to the manufacturer data sheet. If linear encoders are used or for example, a translation ratio must be included, as well as the calculation for the maximum permissible speeds and the scaling parameters that must be defined in the Safety Designer for each encoder, taken into consideration.

Page 33: Installing The Encoder
S-DIAS SAFETY SNC INCREMENTAL ENCODER SNC 021 11 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. -
