30.5.9 Normal Pulse Output (LT Series)

Pulse output includes normal pulse output, which outputs a frequency set to a predetermined pulse-output number, and acceleration/deceleration pulse output, which gradually increases the frequency up to a set pulse-output value. Up to four normal pulse outputs can be used. A positioning-control motor can be driven by connecting a CW or CCW stepping motor or connecting a CW or CCW servo-motor amplifier. The main features of normal pulse output are shown in the following table.

Summary

In GP-Pro EX, you can set up the initial value for each parameter. After the system is running, you can change parameters with system variables.

The procedure for setting the pulse output is summarized below.

Setting Up Initial Values

Refer to the setup procedures for GP-Pro EX.

 

Changing After System is Running

  1. Set the output frequency and the Output pulse count.

  2. Change the parameter under [Request Special I/O Parameter Change].

  3. Under [Special I/O Parameter Change Completed], acknowledge that the parameter has been changed.

  4. Output the data with [Control Special I/O].

  5. See "Special I/O state" for acknowledgment.
