Statistics data for device service life
• Operating hours
The soft starter records 2 operating hour values:
– The motor operating hours.
These indicate how long the motor has been switched on.
– The device operating hours (soft starter).
These indicate how long the 115 V AC or 230 V AC supply voltage of the soft
starter has been switched on.
Both operating hour values are recorded in data set 95 - "Read statistics".
They are recorded in the "Operating hours" data field once every second.
The operating hours are recorded in the range of 0 to 2
32
seconds in
1-second increments.
• Number of overload trips
The soft starter counts the number of overload trips in the range of
0 to 65535.
• Number of starts motor right / left
The soft starter counts the number of starts in the range of 0 to 2
32
.
Example: The value is increased by 1 when current is flowing in the main
circuit following a "Motor ON" command.
• Number of starts, outputs 1 to 4
• Motor current I
max
.
The soft starter measures the current in all 3 phases and indicates the current
of the phase with the highest load as a percentage [%] of the set current I
e
.
Data format: 1 byte, 8-bit current format
Example: Set current I
e
=60A
Indicated motor current 110 %
corresponds to 60 A x 1.1 = 66 A
All 3 phase currents are available in data set 94
• Last trigger current
The soft starter measures the current in all 3 phases and indicates the current
flowing through the phase with the highest load at the time of the tripping as a
percentage [%] of the set current I
e
and in amperes [A]
Data format: 2 byte, 9-bit current format
Example: Set current I
e
= 60 A
indicated motor current 455 % corresponds to 60 A x 4.55 = 273 A
