5.2.3 Configuring the Pulse Encoder Feedback
You only need to configure the pulse encoder feedback parameters if you have the
Pulse Encoder (Tachometer) kit installed. If you have a regenerative drive, you must
use a quadrature pulse encoder.
The pulse encoder block diagram is shown in figure 5.4.

ATTENTION: The incorrect configuration of these parameters can cause
an overspeed condition. These parameters must be set by a qualified
person who understands the significance of setting them. Failure to
observe this precaution could result in bodily injury.
