7.18 Warnings
The Softstarter has a number of warning functions to
signal malfunctioning or other potential risks, before
asserting the protection or fault. The difference between
a warning and a protection is that a warning cannot stop
the Softstarter and a reset of a warning is not necessary.
The warning level and all other additional information to
enable the warning can be set by the user.
A warning is stored in the event list. Warnings can be
Enable or Disable. There is sometimes a percentage
setting were the user can set at which percentage level
the warning occurs.
Set warnings to an Event group by the Out parameter.
The Event group can be set for relay output to control
other devices in an application.
As default, all parameters are set to the same
Eventgroup.
Warnings show on the HMI, but do not change the
behavior of the Softstarter.
7.18.1 Electronic overload warning
The motor temperature is higher than the set warning
level, % of max temperature.
Electronic overload warning has these parameters:
Parameter Description Setting range Default value
20.01 EOL level Sets the EOL warning level. 40.0 ... 99.0% 90.0%
20.02 EOL out Identifies the Event groups this
warning is part of.
Eventgroup 0 ... 6 0000100
23.03 EOL warning Enables EOL warning. Off, On Off
7.18.2 Locked rotor warning
A warning signal will be given if the current exceeds the
settable warning level.
The motor is running stiff.
Locked rotor warning is configured with the
following parameters:
Parameter Description Setting range Default value
20.04 Locked rotor level Sets the Locked rotor warning level. 0.2 ... 10.0 x I
e
1.2 x I
e
20.05 Locked rotor init time Sets the time delay after top of
ramp when the warning is enabled.
1.0 ... 30.0 s 5 s
20.06 Locked rotor out Identifies the Event groups this
warning is part of.
Eventgroup 0 ... 6 0000100
20.07 Locked rotor Enables locked rotor warning. Off, On Off
20.10 Locked rotor trip time Sets the time that the rotor is
locked before trip.
