(1) What is a pulsar?
Generally, pulsars look like the one in Figure 17.
The rotating dial is equipped with an encoder,
and can be turned with the handle on the dial.
The dial is just like the dial on a safe. It clicks as
it turns. Turn it clockwise to move in the positive
direction.
The pulsar in the photo on the left has two rotary
switches. The left rotary switch is used to select
the axis to move (up to six axes can be
addressed separately). The right rotary switch is
used to select the units (how many pulses per
tick on the dial).
Basically, most pulsars can output A/B phase
signals.
When an operator needs to adjust the position of
a workpiece on a stage, push buttons may be
used to adjust it in a positive or negative
direction. However, in order to make fine
adjustments to the position, the pulsar may be
more efficient.

An bare encoder with a marked dial, as shown to the left,
