Parameter Description
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.
Select Quick Menu >Loggings: Trending Continued Bin /
Trending Timed Bin / Trending Comparison.
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
hour.

monitored for Trending.
[0] 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 Output frequency to the motor. Reference for
[Hz] the relative value is the maximum output
frequency programmed in 4-14 Motor Speed
High Limit [Hz]. Actual value can be read in
16-13 Frequency.
[3] Motor Speed Speed of the motor. Reference for relative
[RPM] value is the maximum motor speed

Function:
programmed in 4-13 Motor Speed High Limit
[RPM].
Function:
[0 - Array with 10 elements ([0]-[9] below
4294967295 ] parameter number in display). Press OK and
step between elements by means of
buttons on the LCP.
10 counters with the frequency of occurrence
for the operating variable monitored, sorted
according to the following intervals:
Counter [0]: 0% - <10%
Counter [1]: 10% - <20%
Counter [2]. 20% - <30%
Counter [3]: 30% - <40%
Counter [4]: 40% - <50%
Counter [5]: 50% - <60%
Counter [6]. 60% - <70%
Counter [7]: 70% - <80%
Counter [8]. 80% - <90%
Counter [9]: 90% - <100% or Max
The above minimum limits for the intervals
are the default limits. These can be changed
in 23-65 Minimum Bin Value.
Starts to count when the frequency converter
is powered up for the first time. All counters
can be reset to 0 in 23-66 Reset Continuous Bin
Data.
