Analog-Reference
Motor speed command: -10V to +10V, corresponds to the maximum speed
programmed P1-55 Maximum Speed Limit (Factory default 3000 RPM).
![Page 20: AC Servo Drives- Delta ASDB B Series](https://reader037.fdocuments.us/reader037/viewer/2022100218/55a470d31a28abac568b457f/html5/thumbnails/20.jpg)
Torque Reference
Motor torque command: -10V to +10V, corresponds. to -100% to +100%
rated torque command.
![Page 21: AC Servo Drives- Delta ASDB B Series](https://reader037.fdocuments.us/reader037/viewer/2022100218/55a470d31a28abac568b457f/html5/thumbnails/21.jpg)
Pulse & Sign
These pins are used to get Pulse input from the External controller
Example: PLC.
![Page 22: AC Servo Drives- Delta ASDB B Series](https://reader037.fdocuments.us/reader037/viewer/2022100218/55a470d31a28abac568b457f/html5/thumbnails/22.jpg)
Encoder Pins
The motor encoder signals are available through
these terminals- A, B, Z output signals. The output
maximum voltage is 5V and the maximum
permissible current is 200mA.
![Page 23: AC Servo Drives- Delta ASDB B Series](https://reader037.fdocuments.us/reader037/viewer/2022100218/55a470d31a28abac568b457f/html5/thumbnails/23.jpg)
VDD
VDD is the +24V source voltage provided by the drive. Maximum
permissible current is 500mA.
![Page 24: AC Servo Drives- Delta ASDB B Series](https://reader037.fdocuments.us/reader037/viewer/2022100218/55a470d31a28abac568b457f/html5/thumbnails/24.jpg)
COM+ & COM-
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-.

DO Signal- Digital Output- To get feedback from the Servo on various signals like SERVO ON,
SERVO READY, ZERO SPEED etc.
![Page 27: AC Servo Drives- Delta ASDB B Series](https://reader037.fdocuments.us/reader037/viewer/2022100218/55a470d31a28abac568b457f/html5/thumbnails/27.jpg)
DI Signal- Digital Input- To give commands from External source for operation control like
SERVO ON, Clockwise limit, Counter Clockwise Limit, Alarm Reset,
Emergency Stop etc.
