Step 6 – Monitor Test – Verify Network Host Can Monitor Inverter
This step requires that you have completed the previous 5 steps, and that the powerup
test during the installation was successful (see "Running the Motor" on page 25). At this
point in the procedure, the inverter is using front panel keypad inputs for Run/Stop
commands. The DeviceNet host computer can monitor inverter operation without
actually controlling the inverter. So, you do not have to change any "P Group" parame-
ters from their defaults to do this network monitoring test.
Inverter Status LEDs – The two status LEDs on the
inverter's front panel are to the right of the Stop key.
• MS – Module Status
• NS – Network Status
The status LEDs may be green or red, and may or OFF,
ON, or flashing between OFF and ON. The table below
shows how to interpret the status LED indications. (At
this point, the correct status is MS=green, NS=OFF.)
