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.

Pin No
Motor speed command: -10V to +10V, corresponds
42
to the maximum speed programmed P1-55
Maximum Speed Limit (Factory default 3000 r/min).
Motor torque command: -10V to +10V, corresponds
18
to -100% to +100% rated torque command.
The MON1 and MON2 can be assigned drive and
motor parameters that can be monitored via an
analogue voltage.
16
Please reference parameter P0-03 for monitoring
15
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
41
inputs: Open Collector and Line Driver.
43
Three different pulse commands can be selected via
37
parameter P1-00. Quadrature, CW + CCW pulse &
36
Pulse / Direction.
Should an Open Collector type of pulse be used this
35
terminal must be lulled high to pin 17.
The drive can accept two different types of pulse
inputs: Open Collector and Line Driver.
46
Three different pulse commands can be selected via
40
parameter P1-00. Quadrature, CW + CCW pulse &
38 Pulse / Direction. These signals are used for ASDA-
A+ series only. In ASDA-A series, these terminals
29
are marked ""NC", which means "No Connection"
and must be left unconnected.
OA 21
/OA 22
The motor encoder signals are available through
OB 25
these terminals. The encoder output pulse count can
/OB 23
be set via parameter P1-46.
OZ 50
/OZ 24
VDD is the +24V source voltage provided by the
17
drive. Maximum permissible current 500mA.
COM+ is the common voltage rail of the Digital Input
11
and Digital Output signals. Connect VDD to COM+
45
for source mode. For external applied power sink
47
mode (+12V to +24V), the positive terminal should
49
be connected to COM+ and the negative to COM-.
