7.4.9 Trapezoidal Control Instruction (F171)
- This instruction automatically performs trapezoidal control according to the specified data table while
the trigger (execution condition) is on.
- When the deceleration stop is requested by the F0 instruction during the pulse output, the deceleration
stop is performed.
The explanation below shows the case that pulses are output from Y0 with the following conditions;
Initial speed: 1 kHz, Target speed: 10 kHz, Acceleraiton time: 100 ms, Deceleration time: 1000 ms,
Movement amount: 30000 pulses.
