This position is taken from the position feedback device and is not affected by the marker or the freeze inputs.
Each time the marker becomes active the non-marker position values (Pr x.29 to Pr x.31) are sampled and stored in Pr x.32 to Pr x.34.
The freeze input to the SM Universal Encoder Plus can take the following forms
• A 485 signal through the encoder marker simulation output pins
• A 24V signal on the freeze 24V input
• A signal on the internal drive and slot freeze line generated by another Solutions Module.
The selection of which mode used is dependent on the value of Pr x.38. The default is 1 that corresponds to only the 24V input to this Solutions
Module. The values correspond to the modes as described in the table below:
