6. Data Transmission and Comparison Design Examples 6.4 FMOV - Single Data Broadcasting X2 X3 X4 30Hz 40Hz 0Hz X1 50Hz Frequency Selection RS485 1# ACMD 2# ACMD 3# ACMD 4# ACMD Control Purpose: z Setting frequency of 4 ACMDs (AC Motor Drive) by selecting on the rotary switch. In some applications users may need to set the frequency on several ACMDs to be the same when a Delta PLC is connected through RS485 communication format. The control purpose can be achieved by controlling the value in D10~D13 which corresponds to 4 frequency of four ACMDs, and then adjusting the frequency by one external rotary switch. Devices:
DVP-PLC Application Examples 6-5 Device Function X1 X1 = ON when the switch is turned to “0Hz”. X2 X2 = ON when the switch is turned to “30Hz”. X3 X3 = ON when the switch is turned to “40Hz”. X4 X4 = ON when the switch is turned to “50Hz”.
