Declaration of parameters
Trip class
The trip class (CLASS) specifies the maximum time within which a protective device must
trip from a cold state at 7.2x the setting current (motor protection to IEC 60947).
For more information, see Chapter Overload protection (Page 76).
Rated operational current I
e
This is where you can enter the rated operational current that the branch (switchgear and
motor) can carry without interruption. The setting range depends on the relevant device's
rating class.
For more information, see Chapter Rated operational current (Page 67).
Blocking current
If the blocking current is overshot, the motor starter detects stalling.
For more information, see Chapter Blocking time and blocking current (Page 95).
Blocking time
The blocking time is the time a motor block can be permitted without tripping the motor. If the
blocking time expires and the system is still stalled, the motor starter switches off.
For more information, see Chapter Blocking time and blocking current (Page 95).
Diagnosis Electronics supply voltage too low
With this device parameter, you define whether a message is to be displayed if the supply
voltage is too low (as of firmware V1.2.0).
Input n action
Different actions can be triggered when an input signal is present.
You can find out which actions you can parameterize depending on "Input n level",
"Input n signal" and "Mode" in chapter Inputs (Page 104).
Input n level
You use this device parameter to specify the input logic.
For more information, see Chapter Inputs (Page 104).
