PID command value SV The PID command value and PID feedback amount are displayed
after conversion to the virtual physical values (e.g., temperature or
pressure) of the object to be controlled using function code E40 and
E41 data (PID display coefficients A and B).
Display value = (PID command value or feedback amount)
×
(Coefficient A - B) + B
PID feedback amount PV
PID output value MV
PID output value, displayed in % (assuming the maximum frequency
(F03) as 100%).
5
Torque limit value A TLA Driving torque limit value A (based on motor rated torque)
Torque limit value B TLB Driving torque limit value B (based on motor rated torque)
Reference torque bias TRQB Reserved.

Basic key operation
(1) Turn the inverter ON. It automatically enters Running mode. In that mode, press the
key to switch to Programming mode and
display the menu screen.
(2) Move the pointer
Æ
to "3. OPR MNTR" with the and keys.
(3) Press the key to establish the selected menu and proceed to a list of monitoring items (consisting of several pages).
(4) Use the and keys to select the page on which the desired monitoring item is shown, then check the running status
information of that item.
(5) Press the key to go back to the menu screen.
Figure 3.12 shows an example of the LCD screen transition starting from Menu #3 "Drive Monitoring."
(1) To display this menu screen, press
key in Running mode to switch to Programming mode.
(2) Move the pointer
Æ
to "3. OPR MNTR" with and keys. /
