Power PMAC Clipper User Manual
Connections and Software Setup
29
With quadrature encoders, the Power Clipper has the capability of detecting the loss of an encoder signal.
This is described in detail in the
Encoder Loss Detection
section of this manual.
Note
Note the distinction between the encoder count error, which reports
loss of counts due to bad transitions of the quadrature signals, and
encoder loss, which indicates that one or more quadrature signals are
completely missing.

Differential DAC Output
J3 (JMACH1)
Note
The analog outputs are intended to drive high-impedance inputs with
no significant current draw (10mA max). The 220
output resistors
will keep the current draw lower than 50 mA in all cases and prevent
damage to the output circuitry, but any current draw above 10 mA can
result in noticeable signal distortion. Software setup for analog outputs
can be found in the Drive-Motor setup section.
