Connectable en- Incremental or absolute (SSI) encoders may be connected directly (e.g. digi-
coder types tal-rotary encoders); they are then selected via machine data.
Encoders with SINE/COSINE signals (e.g. length scales) may be connected
by way of an external electronic pulse shaper (EXE) that converts the signals
to 5 V levels.
