You can access important system parameter values with the "D" Group monitoring functions,
whether the inverter is in Run Mode or Stop Mode. After selecting the function code number
for the parameter you want to monitor, press the Function key once to show the value on the
display. In Functions D005 and D006 the intelligent terminals use individual segments of the
display to show ON/OFF status.

Description
Real-time display of output frequency to
motor, from 0.0 to 400.0 Hz
Filtered display of output current to motor
(100 mS internal filter time constant)
Three different indications:
Forward Stop
Displays the scaled PID process variable
(feedback) value (A75 is scale factor)
Displays the state of the intelligent input

8 7 6 5 4 3 2
FW
Terminal symbols
Displays the state of the intelligent output
terminals:
AL 15 14 13 12
Terminal symbols
Displays the output frequency scaled by the
constant in B0086. Decimal point indicates
range:
XX.XX 0.00 to 99.99
XXX.X 100.0 to 999.9
XXXX. 1000 to 9999
XXXX 10000 to 99990
Displays the actual shaft speed of the motor,
converted to frequency
Displays the level of the torque command
when the inverter is set to torque control mode
Displays the level of the torque bias, if
enabled, when the inverter is in vector control
mode with feedback
