Signals Explanation Of Connector Cn1 - Delta Electronics ASDA-AB Series User Manual

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 to
42 the maximum speed programmed P1-55 Maximum
Speed Limit (Factory default 3000 RPM).
Motor torque command: -10V to +10V, corresponds to -
18
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 inputs:
43
Open Collector and Line Driver.
41
Three different pulse commands can be selected via
36
parameter P1-00. Quadrature , CW + CCW pulse &
37
Pulse / Direction.
Should an Open Collector type of pulse be used this
35
terminal must be lulled high to pin 17.
21
22
The motor encoder signals are available through these
25
terminals. The encoder output pulse count can be set
23
via parameter P1-46.

24
VDD is the +24V source voltage provided by the drive.
17
Maximum permissible current 500mA.
COM+ is the common voltage rail of the Digital Input
11
and Digital Output signals. Connect VDD to COM+ for
45
source mode. For external applied power sink mode
47
(+12V to +24V), the positive terminal should be
49
connected to COM+ and the negative to COM-.
VCC is a +12V power rail provided by the drive. It can
20
be used for the input on an analog speed or torque
command. Maximum permissible current 100mA.
12,13,
The polarity of VCC is with respect to Ground (GND).
