Mitsubishi Electric 800 Series Instruction Manual (Function page 319

NOTE
• The number of readout digits of the cumulative energization time (Pr.52 = "20"), actual operation time (Pr.52 = "23"),
cumulative energy (Pr.52 = "25"), and cumulative energy saving (Pr.52 = "51") does not change.
 Enabling display of negative numbers during monitoring (Pr.290)
• Negative values can be used for indication via terminal AM (analog voltage output), communication, and terminal AM0 (of
the FR-A8AY). To check which items can be monitored with indication of negative numbers, refer to Monitor description
list (on page 311).

—: Negative numbers indication disabled (positive only)
*1 Negative numbers indication is disabled via RS-485 communication (Mitsubishi inverter protocol or MODBUS RTU).
NOTE
• When indication with negative numbers is enabled for the output via terminal AM/AM0 (analog voltage output), the output is
within the range of -10 to +10 VDC. Connect the meter with which output level is matched.
• The operation panel displays only unsigned numbers.
 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.
