DVP-ES3 Series Programming Manual 14. Refer to Example 3 from the PLSY instruction (API 2700) for programming in ST language. 15. When the target output frequency is reached, you can change the set target output frequency. The frequencies for ramp up and ramp down are already set, if you change the set target output frequency during the instruction execution, the frequency goes either ramping up or ramping down. If more than one target output frequencies are set, it is suggested to set the last new target frequency the same as the original target frequency to avoid abrupt change when it needs to come to a stop. See the example below.
The blue line indicates the original target freueency and the red line indicates new target frequency. Situation A: ramping up Freq. Time _6 Number of output pulses Ramp up time The first target frequency Position to change to the new target frequency New target frequency Situation B: ramping down Freq. Time 6-770
