(M) Monitor display and monitor output signal
Minus sign display for the monitors (Pr. 290)
● A negative output can be selected for the monitor display of the terminal AM (analog voltage
output), the operation panel, and a communication option. For a list of the monitors that can
output values with minus signs, refer to the monitor description list (on page 5-194).
Pr. 290 setting
0 (initial value)
⎯: Output without minus sign (positive values only)
Tab. 5-93:
● Select items to be displayed with minus signs using Pr. 1018 "Monitor with sign selection".
Types of monitor

Remote output 1
Remote output 2
: Displayed with minus sign,
⎯: Displayed without minus sign (positive only)
Tab. 5-94:
Displayed without minus sign on the operation panel. Confirm the rotation direction with the
[FWD] or [REV] indicator.
NOTES When terminal AM (analog voltage output) is "output with a minus sign", the output will be within
the –10 V DC to +10 V DC range. Connect the meter with which output level is matched.
Parameter unit (FR-PU07) displays only positive values.
