Statistical data on device service life
● Operating hours
The motor starter records 2 operating hours values:
– The operating hours of the motor.
This indicates how long the motor was switched on.
– The operating hours of the device (motor starter).
Indicates how long the 24 V DC LV power supply of the motor starter was switched on
Both operating hours values are recorded in data set 95 – Statistics. They are entered in the
data field "Operating hours" alternately at 5-second intervals. The bit "Operating hours
selection" specifies which of the two operating hours values has been transferred.
[0]: Operating hours - motor
[1]: Operating hours - device
The operating hours are recorded in the range from 0 to 16,777,215 minutes in 1-second
steps.
● Number of overload trips
The motor starter counts the number of overload trips in the range 0 to 65,535.
● Number of starts motor CW/CCW
The motor starter counts the number of starts in the range 0 to 16,777,215.
Example: The value is incremented by 1 when the current is flowing in the main circuit
after the "Motor ON" command has been issued.
● Motor current I
max
.
The motor starter measures the current in all 3 phases and displays the current of the
phase under the greatest load as a percentage [%] of the setting current I
e
.
Data format: 1 byte, 8-bit current format
Example: Setting current I
e
= 10 A
Indicated motor current 110%
then corresponds to 10 A x 1.1 = 11 A
All 3 phase currents are available in data set 94
● Last tripping current
The motor starter measures the current in all 3 phases and displays the current that is
flowing in the phase under the greatest load when the trip occurs as a percentage [%] of
the current setting I
e
and in amperes [A]
Data format: 2 bytes, 9-bit current format
Example: Setting current I
e
= 10 A
Indicated motor current 455% then corresponds to 10 A x 4.55 = 45.5 A
