 Enabling display of negative numbers during monitoring (Pr.290)
• Negative signal outputs can be selected for the items monitored via terminal AM (analog voltage output), via a
communication option, and on the operation panel. To check which items can be monitored with indication of negative
numbers, refer to the monitor items list (on

○: Negative numbers displayed with minus sign, —: Negative numbers not displayed (positive only)
*1 Negative numbers are not displayed on the operation panel. Confirm the rotation direction with the [FWD] or [REV] indicator.
NOTE
• When the output via terminal AM (analog voltage output) is set to "Negative numbers indication enabled", the output is within
the range of -10 to +10 VDC. Connect the meter with which output level is matched.
• Parameter unit (FR-PU07) displays only positive values.
 Monitor filter (Pr.1106 to Pr.1108)
• The response level (filter time constant) of the following monitor indicators can be adjusted. Increase the setting when a
monitor indicator is unstable, for example.
