5.6 Explanation of the bank automatic switching function
■ Regarding the bank automatic switching function
The bank function can be automatically switched for each temperature. Setting control parameters for
each temperature beforehand enables realization of optimization and an accurate control. As
parameters unrelated to control can also be set similarly to the case of the normal bank function,
application for each temperature is possible for such functions as the timer and event functions.
Note Precaution when using this function together with the program run function
When using this function together with “program run,” the setting is ineffective even when the
bank designation is set using SET 22 “St*bK step* designated bank setting.” All banks are used
with priority when using the bank automatic switching function [SET 23 BAF

1]. Note that a
bank cannot be divided into parts for assigning one of them to, for example, a program run.

Eight banks at most (threshold

7) can be used; the diagram is an example of all banks used. The
bank can automatically be switched for each temperature. The zone threshold* setting < PM 1 to PM
7 > is set in the SV value setting range from SLL to SLH.
The threshold required for automatic switching is set in SET 23 “bank automatic switching function
setting mode.”
For this function, SET 20 “bank function” must be set beforehand.
