Monitor description list (Pr. 52, Pr. 774 to Pr. 776, Pr. 992)
●
Set the monitor to be displayed on the operation panel and parameter unit in Pr. 52, Pr. 774 to Pr.
776, Pr. 992.
●
Refer to the following table and set the monitor to be displayed. (The monitor marked ⎯ cannot
be selected. "  " in the [Minus (-) display] indicates a display with a minus sign.)

Excitation current monitor filter 9999
0 to 5 s
The filter time constant is selectable
for monitoring of the motor
excitation current. A larger setting
results in slower response.
