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.
