Pr.128
= "99"
Pr.195
*1
Prepare a power supply matched to the power supply specifications of the detector.
*2
The output signal terminal to be used differs according to the Pr.195 (Output terminal function selection) setting.
*3
The input signal terminal to be used differs according to the Pr.178 to Pr.182 (Input terminal function selection) setting.
*4
There is no need to input AU signal.
 Input/output signals
• Assigning the PID control valid (X14) signal to the input terminal by
enables PID control to be performed only when the X14 signal is turned ON. When the X14 signal is OFF, regular inverter
running is performed without PID action .
