  • Page 5 related SM elements. The output slows to a stop after driving the power flow to stop. During the drive process, changing the frequency can be responded. And there are the acceleration and deceleration process after modifying the frequency(except Y4/Y5). During Y0 pulse output, SM82 will be set ON and set to OFF after execution. Y0~Y7 support the output completion interrupt.
  • Page 6 Note: Take Y0 as an example: the actual acceleration and deceleration time is not SD205, which SD205 is the time from SD202(32-bit) to SD204 (16-bit). If a frequency f is set, then the actual acceleration and deceleration time t =SD205*( f -sd204)/(SD202-SD204), and the acceleration and deceleration times of other axes can be referred to the corresponding SD elements.
