5.6 Inverter Setup

The inverter drive has a separate display and

keypad as detailed on the left. The display is set as

standard to show the frequency output to the pump

motors, but repeated pressing of the key with the

circular arrow, will also show also the frequency

reference value and current drawn by the pump.

There are 79 adjustable parameters within the

inverter that have been factory preset to the values

shown in the table below (for full information on

each parameter, refer to the inverter drive guide).

Parameter n01, when set to 0, locks parameters

n02 to n79 (set n01 to 1 for adjustment) –

parameters can only be changed when in the

PRGM mode and the inverter is not operational.

The Run, Stop/Reset keys and the frequency

setting potentiometer are for manual operation only

and have been disabled in the setup.

If the inverter goes to a fault condition the red alarm

LED will blink on and off and an alarm code will

show in the inverter display window (refer to inverter

guide for full details).

Parameter n78 will display a fault code if the inverter goes into a fault condition. This information will be

required by the CDU manufacturer for fault diagnosis.
