for Output Frequency and Motor Speed.
The size of each interval can be adjusted individually, but will
default be 10% for each. Power and Current can exceed
rated value, but those registrations will be included in
90%-100% (MAX) counter.

Once a second, the value of the operating variable selected
is registered. If a value has been registered to equal 13%, the
counter “10% - <20%” will be updated with the value “1”. If
the value stays at 13% for 10s, then “10” will be added to the
counter value.
The contents of counters can be displayed as bars on LCP.

NOTE
The counters starts counting whenever the frequency
converter is powered-up. Power cycle shortly after a reset
will zero the counters. EEProm data are updated once per

Power [kW] Power yielded to the motor. Reference for the
relative value is the rated motor power
programmed in
1-20 Motor Power [kW] or
1-21 Motor Power [HP] . Actual value can be
read in 16-10 Power [kW] or 16-11 Power [hp] .
[1] Current [A] Output current to the motor. Reference for the
relative value is the rated motor current
programmed in
1-24 Motor Current . Actual
value can be read in 16-14 Motor Current .
[2] Frequency
[Hz] Output frequency to the motor. Reference for
the relative value is the maximum output
frequency programmed in
4-14 Motor Speed
