(M) Monitor display and monitor output signal
358
PARAMETERS
 Monitor description list (Pr.54, Pr.158)
• Set Pr.54 FM terminal function selection for the monitor to be output to the terminal FM (pulse train output).
• Set Pr.158 AM terminal function selection for the monitor to be output to the terminal AM (analog voltage
output). Output with a negative sign can be made (-10 VDC to +10 VDC) from the terminal AM.

in the [Negative (-)
output] indicates the output value is negative at the terminal AM. (For setting of the output with/without minus sign, refer to
page 347 .)
• Refer to the following table and set the monitor to be displayed. (Refer to page 348 for the monitor description.)
