 Monitor items list (Pr.52, Pr.774 to Pr.776, Pr.992)
• Use Pr.52, Pr.774 to Pr.776, or Pr.992 to select the item to monitor on the operation panel or the parameter unit.
• Refer to the following table to find the setting value for each monitoring. (The items marked with "—" cannot be selected.
The circle in the [-] column indicates that the indication of negative signed numbers is available.)

Each of the initial items monitored on the operation panel or
parameter unit in the monitor mode (output frequency,
output current, and output voltage) can be switched to an
user-designated item.
9999: Follows the Pr.52 setting.
Select the monitor item displayed on the operation panel at
the time when the setting dial is pressed.
Set "0" to clear the watt-hour meter.
Set "10" to monitor the cumulative power in the range of 0 to
9999 kWh via communication.
Set "9999" to monitor the cumulative power in the range of
0 to 65535 kWh via communication.
The number of times that the cumulative energization time
exceeded 65535 hours is displayed (read-only).
Value is displayed in 1 increments (an integer).
Value is displayed in 0.1 increments.
No function
Set the number of digits to move the decimal point of the
cumulative energy monitored value to the left. The readout
peaks out at the upper limit of readout.
The function of moving the decimal point is not available.
The readout is reset to 0 when it exceeds the upper limit.
Set "0" to clear the operation hour meter.
The readout is always 9999. Nothing changes when "9999"
is set.
The number of times that the operating time reaches 65535
hours is displayed. Read-only.
Set the availability of negative signals output via terminal
AM, to the operation panel, and through communication.
(Refer to page 433.)
Select the item group to enable the indication of negative
signed numbers.
The filter time constant is selectable for monitoring of the
torque. A larger setting results in slower response.
0.3 s filter
The filter time constant is selectable for monitoring of the
running speed. A larger setting results in slower response.
0.08 s filter
The filter time constant is selectable for monitoring of the
motor excitation current. A larger setting results in slower
response.
