CHAPTER 7 PROGRAMMING

7.2 When Using the Module in a Standard System Configuration
7.2.2 Standard control (peak current suppression function, simultaneous temperature rise function)
• Program example where the simultaneous temperature rise function is used
This program is designed to classify the CH1 and CH2 into group 1 and CH3 and CH4 into group 2 so that
the channels in each group reach the set values (SV) simultaneously.
(3) Wiring example
The following figure shows a wiring example.
