11.4.2 Manual pulse generator operation execution procedure

The manual pulse generator operation is carried out by the following procedure.

Preparation

STEP 1

Refer to Chapter 5 and Section 11.4.3.

STEP 2

Refer to Section 11.4.4.

Set the parameters

)

Pr.1 to Pr.24 )

Set " Cd. 20 Manual pulse generator 1 pulse input magnification". (control data setting)

Create a sequence program in which the enable/disable is set for the manual pulse generator operation.

(" Cd. 21 Manual pulse generator enable flag" setting.)

One of the following two methods can be used. <Method 1>

Directly set (write) the parameters in the QD75 using GX Configurator-QP.

<Method 2>

Set (write) the parameters from the PLC CPU to the QD75 using the sequence program (TO command).

Using GX Developer, set the control data and create a sequence program to enable/disable the manual pulse generator operation. (Set the control data in the QD75 buffer memory using the TO command.)
