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.
Part of the settings can also be set up with logic program I/O driver instructions.31.23 I/O Driver Instructions
Setting Up Initial Values
Refer to the setup procedures for GP-Pro EX
Changing After System is Running
Set the output frequency, output pulse count, initial output frequency, and acceleration/deceleration time.
Set the parameter [Create Acceleration/Deceleration table request].
Under [Create Acceleration/Deceleration table complete], acknowledge that the parameter has been changed.
Under [Control Special I/O], turn ON the acceleration/deceleration bit.
Output the data with [Control Special I/O].
See "Special I/O state" for acknowledgment.
Acceleration and deceleration pulse outputs have a limit to the output frequency and pulse count.
