Illustration 3.64 Time and Relative Values
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% is updated with the
value 1. If the value stays at 13% for 10 s, 10 is added to
the counter value.
The contents of counters can be displayed as bars on the
LCP. Select

Loggings : Trending Continued Bin/
Trending Timed Bin/Trending Comparison .
NOTICE
The counters start counting whenever the frequency
converter is powered up. Power cycle shortly after a
reset zeros the counters. EEPROM data are updated once
per hour.
23-60 Trend Variable
Option: Function:
Select the desired operating variable to be
monitored for trending.
[0] Power [kW] Power yielded to the motor. Reference for the
relative value is the rated motor power
programmed in
parameter 1-20 Motor Power
[kW] or parameter 1-21 Motor Power [HP] . Actual
value can be read in parameter 16-10 Power
[kW] or parameter 16-11 Power [hp] .
[1] Current [A] Output current to the motor. Reference for the
relative value is the rated motor current
programmed in
parameter 1-24 Motor Current .
Actual value can be read in
parameter 16-14 Motor current
.
[2]
*
Frequency
[Hz] Output frequency to the motor. Reference for
the relative value is the maximum output
frequency programmed in
parameter 4-14 Motor Speed High Limit [Hz] .
Actual value can be read in
parameter 16-13 Frequency .
[3] Motor
Speed
[RPM]
Speed of the motor. Reference for relative
value is the maximum motor speed
programmed in
parameter 4-13 Motor Speed
High Limit [RPM] .

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%
