30.5.10 Acceleration/Deceleration 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 accelerating pulse outputs can be used. The main features of accelerating 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 acceleration/deceleration 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, output pulse count, initial output frequency, and acceleration/deceleration time.

  2. Set the parameter [Create Acceleration/Deceleration table request].

  3. Under [Create Acceleration/Deceleration table complete], acknowledge that the parameter has been changed.

  4. Under [Control Special I/O], turn ON the acceleration/deceleration bit.

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

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