Chapter 12  Application Examples 
12.1  Connecting to DVP-EH PLC and DOP-A HMI 
Application Example: Dual Mode (S-P Mode) 
Purpose 
Use Delta DVP-EH series PLC to output pulse command (Homing operation, JOG operation, forward and 
reverse operation, and speed control mode switching) and enable ASDA-B servo drive. Also, use Delta 
DOP-A series HMI to control ASDA-B servo drive and let the servo drive follow the commands from PLC to 
complete the positioning.  
Explanation:  
Programmable Logic Controller (hereinafter “PLC”) 
1.  Delta DVP-EH series PLC is “Transistor Output” Model. The definition of output contacts is as follows: 
Y0: Pulse 
Y1: SIGN 
Y2: In speed control mode, parameter P1-09 is used to set speed 1 of internal speed command. 
Y3: In speed control mode, parameter P1-10 is used to set speed 2 of internal speed command. 
Y4: S-P dual mode: When S-P signal is Off, it is speed mode. When S-P signal is On, it is position mode. 
Y5: Servo ON 
2.  Pulse command is open-collector signal.
