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.

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-

Time

CIO 0002.00 is turned ON when
CIO 0003.00 turns ON.

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.
