Pulse Outputs Section 7-6

Using PLS2(887) for Trapezoidal Acceleration/Deceleration

In this example, the axis is accelerated in the CW direction at 500 Hz/2 ms, the acceleration/deceleration rate is reduced to 300 Hz/2 ms, and the pulse output is stopped after 300,000 pulses have been output.

After 5 s, the same trapezoidal acceleration/deceleration operation is per- formed in the CCW direction.

When CIO 0002.00 goes ON, pulses are output from port 1 in the CW direction with the following settings: Acceleration rate: 500 Hz/2ms Deceleration rate: 500 Hz/2ms Target frequency: 20,000 Hz (20 kHz) Starting frequency: 500 Hz Number of output pulses: 300,000

The 5 s timer starts if A624.00 is ON (pulse output completed).

After the pulse output is completed in the CW direction and 5 seconds have passed, the same pulse output pattern is performed in the CCW direction.

Note When PLS2(887) cannot perform trapezoidal positioning with the trapezoidal acceleration/deceleration settings, it will perform triangular positioning with the same acceleration/deceleration settings. In this case, the PLS2(887) Tar-
