6.9 Encoder (optional)
6.9.1 General description
The encoder produces an incremental coding of the position value detected with signals A and B
(A inverted and B inverted) in phase quadrature; it also provides the Zero and inverted Zero
signals (see the figures below).The signals are shown on the outside as illustrated in section 4.8
“Electronic connections for models with electronic connectors”.
There are three encoder models available:
 "Square Wave" from the manufacturer;
 Lenord+Bauer "Square Wave";
 "Sine" (Lenord+Bauer).

If the shaft stops while the tool is still being pushed against the piece being
machined, the spindle bearings may break. If the tool is not immediately moved
away from the piece and the rotation stopped, there is a risk of burning out the
stator.
