3.3.2 Signals Explanation of Connector CN1
The Tables 3.A, 3.B, & 3.C detail the three groups of signals of the CN1 interface. Table 3.A details the
general signals. Table 3.B details the Digital Output (DO) signals and Table 3.C details the Digital Input
(DI) 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 users.

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.

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. These signals are used for ASDA-
A+ series only. In ASDA-A series, these terminals
are marked “”NC”, which means “No Connection”
and must be left unconnected.

The motor encoder signals are available through
these terminals. The encoder output pulse count can
be set via parameter P1-46.

VDD is the +24V source voltage provided by the
drive. Maximum permissible current 500mA.

COM+ is the common voltage rail of the Digital Input
and Digital Output signals. Connect VDD to COM+
for source mode. For external applied power sink
mode (+12V to +24V), the positive terminal should
be connected to COM+ and the negative to COM-.
