In addition to the parameter values and the pico-PLC instructions, the display may show the
following messages:
r. xx
At the time of power-up this message indicates the software version installed (2
seconds approx.).
IdLE
At power-up and in correspondence with Pr0 this message shows that no alarms are
present and the system is disabled.
run
At the time of power-up and in correspondence with Pr0 this message indicates that
no alarms are present and the drive is enabled; the motor shaft may be spinning.
Er. xx
In correspondence with Pr0 this message indicates that the drive has detected an
alarm (xx indicates the alarm code) and has therefore been disabled. When an alarm
is detected the display automatically switches to parameter Pr0 and shows the alarm
code.
dcbuS
In correspondence with Pr0 this message indicates that the drive is not operating at
low voltage (b40.10=0) and that DC bus voltage is still below the 120 V threshold;
the inrush current circuit is still connected so the drive is not yet ready (b41.4=0).
Prxx
Indication of parameter xx (value displayed by pressing “M”).
Pb. xx
