DELTA PLC [ COMMUNICATION DESIGN EXAMPLE] DELTA SERVO DRIVE ASD-A SERIES --AC DRIVE

Program Description: 1.Initialize PLC RS-485 communication port and set the communication format as MODBUS 2-ASCII, 9600, 7, E, 1. The RS-485 communication format of AC servo drive should be the same with PLC. 3-When M0 = ON, [MODRD K1 H10F K2] instruction will be executed to read the rotation 4-number and the pulse number of internal position 1 and store them in D1050 and D1051. 5-When M1 = ON, [MODWR K1 K16 H10F D10 K2] instruction will be executed to write the 6-content in D10 and D11 into H10F (Rotation number of internal position1) and H10 (pulse number of internal position 1). 7-Both the start signal and the trigger signal are controlled by switches of AC servo drive 8-through the external wiring. For the wiring methods, please refer to the wiring diagram. 9-There are only 4 situations for MODBUS communication: flag M1127 for normal 10-communication and M1129, M1140, M1141 for communication errors. Counter C0 counts 11-once when any of the 4 flags is ON. Therefore, the program assures the communication 12-reliability by monitoring the On/Off status of the 4 flags and performs 2 MODBUS instructions in order by the value in counter C0. 13-Once PLC starts running, the read/write actions for AC servo drive will be performed repeatedly according to [LD=] instructions
