Monitor description list (Pr. 54, Pr. 158)
●
Set Pr. 54 "FM/CA terminal function selection" for the monitor to be output to the terminal FM
(pulse train output) and terminal CA (analog current 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 V DC to +10 V DC) 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 5-358.)
●
Refer to the following table and set the monitor to be displayed. (Refer to page 5-345 for the
monitor description.)
