15. Handy Instruction Design Examples X0 Motor running forward to lift the goods Set the value of start/end ramp signal when lifting goods X1 Executing gradual lifting Motor running reverse to land the goods Set the value of start/end ramp signal when landing goods Executing gradual landing X2 Set the value of start/end ramp signal when stopping goods M0 M1 At the start of lifting or landing goods, the content in D2 will increase gradually from 0 to 2,000 in 2 sec. When stopping goods, the content in D2 will decrease gradually from 2,000 to 0 in 2 sec. M2 M1029 Reset M0~M2 when Ramp process is completed. M1000 Send the content in D2 to D1116.
The content in D1116 determines the output voltage and the current in the first analog output channel of DVP10SX PLC Program Description: z This program applies to PLCs with analog output function, such as DVP20EX and DVP10SX series MPU. In DVP10SX, when the content in D1116 changes from K0 to K2000, the output voltage of the first channel will vary from 0 to 10V. z The parameter of RAMP instruction is directly related to the scan cycle, so users should set the scan cycle at the start of the program first, then the duration of ramp signal can be fixed.
