ASDA A2-E Chapter 1 Coe Drive Overview 1.5.1 Explanation of I/O (CN1) Connector Signal The following details the signals listed in previous section. General Signals 1-8 Revision April, 2015 Wiring Method Signal Name Pin No Function (Refer to 3.4.3) Position pulse (output) OA /OA 17 18 Encoder signal output A, B, Z (Line Driver output) C13/C14 OB /OB 19 20 OZ /OZ 21 22 Power VDD 5 VDD is the +24V power provided by the drive and is for Digital Input (DI) and Digital Output (DO) signal. The maximum current is 500mA. - COM+ 6 COM+ is the common input of Digital Input (DI) and Digital Output (DO) voltage. When using VDD, VDD should be connected to COM+.
If not using, it needs to apply the external power (+12V ~+24V). Its positive end should connect to COM+ and the negative end should connect to COM-. COM- 14 GND 16 VCC voltage is based on GND. Other NC 15 NO CONNECTION. This terminal is for internal use only. Do not connect it, or it may damage the servo drive.
