(1) Output signal list (Pr.54, Pr.158)
• In Pr. 54, set the monitor to be output to the terminal CA (Analog output (0 to 20 mADC current output)).
• In Pr. 158, set the monitor to be output to the terminal AM (analog output (0 to 10VDC voltage output)).
• Refer to the following table and set the monitor to be output.
