After any of the status displays is selected, the corresponding symbol appears. Press SET to show the status display
definition. Note that only at power-on, the parameter-selected display symbol is displayed for 2s and the definition is
then displayed.
When any of the cumulative feedback pulse, droop pulse and cumulative command pulse values displayed is negative,
the decimal points in the second, third, fourth and fifth digits are lit.
