7.16.3 Thyristor overload warning
A warning signal will be given if the thyristor temperature
has exceeded the settable warning level. The warning
says that the softstarter is approaching overheating value
and will tripp if the heat is not removed.
Check the starting conditions and the fans.
Increase current limit if needed.
Thyristor overload warning is configured with the
following parameters:
Parameter Description Setting range Default value
20.08 Thyristor OL out Specifies the Event groups this
warning belongs to.
Eventgroup 0 ... 6 4
20.09 Thyristor OL Enables thyristor overload warning. Off, On Off
7.16.4 Current underload warning
A warning signal will be given if the line current decreases
below the settable value during continuous operation.
Check that the motor current parameter (Ie) is set
correctly.
Current underload warning is configured with the
following parameters:
Parameter Description Setting range Default value
21.01 Curr underload level Sets the Current underload warning
level.
0.4 ... 1.0 x I
e
0.4 x I
e
21.02 Curr underload trip time Sets the time that the current has to
be under the Warning level to trip.
0 ... 30 s 5 s
21.03 Curr underload delay time Sets the time delay after Top of
ramp when the warning is enabled.
0 ... 10 s 1 s
21.04 Curr underload out Specifies the Event groups this
warning belongs to.
Eventgroup 0 ... 6 4
21.05 Curr underload Enables Current underload warning. Off, On Of
7.16.5 Power factor underload warning
A warning signal will be given if the power factor is below
the settable warning level.
Power factor underload warning is configured with the
following parameters:
Parameter Description Setting range Default value
21.06 Pwr factor underload level Sets the Power factor underload limit. 0.0 ... 1.0 0.5
21.07 Pwr factor underload trip time The time it has to be below limit until trip
in seconds.
0 ... 30 s 5 s
21.08 Pwr factor underload delay time The time until diagnoser starts to work in
Top of ramp.
0 ... 10 s 1 s
21.09 Pwr factor underload out Specifies the Event groups this warning
belongs to.
Eventgroup 0 ... 6 4
21.10 Pwr factor underload Enables Power factor underload warning. Off, On Off
