3-3-2 Signals Explanation of Connector CN1
The tables 3.B, 3.C, & 3.D detail the three groups of signals of the CN1 interface. Table 3.B details the
general signals. Table 3.C details the Digital Input (DI) signals and Table 3.D details the Digital Output (DO)
signals. The General Signals are set by the factory and can not be changed, reprogrammed or adjusted. Both
the Digital Input and Digital Output signals can be programmed by the user.

The MON1 and MON2 can be assigned drive and
motor parameters that can be monitored via an
analogue voltage.
Please reference parameter P0-03 for monitoring
commands and P1-04 / P1-05 for scaling factors.
Output voltage is reference to the power ground.

The drive can accept two different types of pulse
inputs: Open Collector and Line Driver.
Three different pulse commands can be selected via
parameter P1-00. Quadrature, CW + CCW pulse &
Pulse / Direction.
