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.
