Acceleration/deceleration control
The frequency changes as shown in the following diagram according to the setting for the execution timing of the change. In the
Before column, the frequency changes and then becomes steady. When the number of pulses in the preset value is output, the
instruction transitions to the next step. In the After column, the steady pulse frequency is maintained, then the frequency
changes, and the instruction transitions to the next step.
Note:
Depending on the combination of steps and the interrupt input timing, forward and reverse may switch at high frequencies. Program the user
program so that forward and reverse can be switched according to the application specifications that will be used.
17. Next step number
This setting specifies the number of the next step to be executed after the output for the currently executed step is completed.
When the next step number is set to 0, that step becomes the last step, and when pulse output at that step is complete, pulse
output will end.
ARAMP1 instruction (reversible control disabled) timing chart
ARAMP1 instruction, S1 is specified as data register D0200, S2 is specified as internal relay M0000, S3 is disabled, D1 is
specified as data register D0000, D2 is specified as internal relay M0050
When the ARAMP instruction input changes from off to on, pulses are output according to the settings configured by the data
registers. When pulse output starts, M0050 turns on. M0052 turns on while the pulse frequency is increasing or decreasing. When
the number of pulses configured for each step is output, the next step is executed. When pulse output is complete for the step
where the next step number is set to 0, then the pulses will stop. In this situation, M0050 turns off and M0051 turns on.
If the ARAMP instruction input turns off during pulse output, pulse output ends. If the ARAMP instruction input turns on again, the
operation starts from the beginning. Even if the contents of the data registers are changed during pulse output, the change is not
reflected in the pulse output operation. The changed content is reflected the next time the ARAMP instruction is started.
