12. Communication Design Examples motor drive runs forward. D1496 = H1, AC motor drive stops.) z Frequency of AC motor drive can be changed by setting the value in D1497. (D1497 = K4000, the frequency of AC motor drive will be 40Hz.) z Before PLC LINK is enabled between PLC and servo motor, turn on “SON” to start servo and then turn on “SPD0” to ensure the speed mode which controlled by internal registers is enabled. z D1512 in PLC corresponds to communication parameter H0004 of AC servo drive. When X0 = ON, PLC LINK will be enabled and the value of H0004 will be shown in D1512. z D1528 in PLC corresponds to communication parameter H0109 of AC servo drive.
When X0 = ON, PLC LINK will be enabled and the value of H0109 can be specified in D1528. z Rotation speed of servo motor can be changed by the content in D1528. (When D1528 = K3000, the rotation speed of servo motor will be 3000 rpm. z Station No. of Slave should be continuous and different from the station No. of Master. SA/SX/SC/SV/EH/EH2 series PLC can be Master. ES/EX/SS series can not be Master. z When X0 = ON, PLC LINK will be enabled. If enabling action is failed, M1350/M1351 will be OFF and X0 needs to be activated again.. DVP-PLC Application Examples 12-37
