Basic key operation
To monitor the running status on the drive monitor, set function code E52 to "2" (Full-menu mode)
beforehand.
(1) Turn the inverter ON. It automatically enters Running mode. In that mode, press the
key to
switch to Programming mode. The function selection menu appears.
(2) Use the
and keys to display "Drive Monitoring" (
QRG
).
(3) Press the
key to proceed to a list of monitoring items (e.g.
A
).
(4) Use the
and keys to display the desired monitoring item, then press the key.
The running status information for the selected item appears.
(5) Press the
key to return to a list of monitoring items. Press the key again to return to the
menu.

Display value = (Output frequency Hz) u (Function code E50)
The 7-segment letters
appear for 10000 (r/min) or more. If
appear, decrease function code E50 data so that the LED
monitor displays 9999 or below, referring to the above equation.
A
PID command
N/A
Virtual physical value (e.g., temperature or pressure) of the object to
be controlled, which is converted from the PID command using
function code E40 and E41 data (PID display coefficients A and B)
Display value = (PID command) u (Coefficient A - B) + B
If PID control is disabled, "
" appears.
A
PID feedback
amount
N/A
Virtual physical value (e.g., temperature or pressure) of the object to
be controlled, which is converted from the PID command using
function code E40 and E41 data (PID display coefficients A and B)
Display value = (PID feedback amount) u (Coefficient A - B) + B
If PID control is disabled, "
" appears.
