When special high-speed output adapters are connected, the same output numbers in the main unit are assigned
as shown in the table below.
Only wire the appropriate output terminals.
Outputs in special high-speed output adapters and the main unit operate as shown below.

Program example
When the contents of D10 are changed ranging from "0" to "50" in the program example shown below, the average
output from Y000 will be ranging from 0 to 100%.
An error will occur if the contents of D10 exceed 50.
In this program example the FX

Do not use the PWM (FNC 58) instruction with relay-output type main units.
(Considerable output response delay may be generated, chattering may occur in
contacts, or the contact life may be shortened.)
Do not use the PWM (FNC 58) instruction with triac-output type main units.
(Considerable output response delay may be generated.)
Use a transistor output type main unit.
