method.

NOTE 1: Set "1" when a PID optional board (J-PI) is used.

The value entered to the OS terminal of J-PI is assumed as the target value.

NOTE 2: The target value at set "1" is O-L, OI-L input signal, setting or multispeed setting.

This function is used to set a target value level of PID controlling within 0 to 200%.

Initial value

If an analog voltage is entered as a feedback value, the feedback voltage (0 to 10V) corresponds to this target value level setting (0 to 200%). In other words, if, when 5V is entered as the target feedback value of a sensor, it is converted to an internal target value, set 100% as this internal target value.

Auto tuning setting

Select whether to start auto tuning as well as a mode. When 1 or 2 is set, auto tuning is started during the first operation.
