Inter-module Link Function

The inter-module link function has the following two functions:

• Inter-module peak current suppression function

• Inter-module simultaneous temperature rise function
These functions control temperatures with multiple temperature control modules.
The inter-module link function can be used between the temperature control modules having the same control CPU.
Inter-module peak current suppression function
The peak current is suppressed among the temperature control modules.
Up to 64 modules can be divided into 5 groups to suppress the peak current.
Setting a channel with a large heater capacity and the one with a small heater capacity in one group among the temperature
control modules can suppress the scale of the power supply facility.
Compared to the peak current suppression with one module, the scale of the power supply facility can be more suppressed
because the current is controlled thorough an entire system.
