Description
In certain applications, operation of the motor is permitted only in a specified,
preset direction of rotation, to avoid damage. The 3RW55 soft starter detects
the main power rotation via the measurement process. The correspondingly
required main power rotation is determined during first commissioning of the
application. Via the "Response to faulty main power" parameter, you can
determine the response of the 3RW55 soft starter to main power rotation
deviations.
Group error only at ON command (factory setting)
If the 3RW55 soft starter detects a wrong main power rotation, a fault is
generated.
Warn
If the 3RW55 soft starter detects a wrong main power direction, a warning is
generated.
The 3RW55 soft starter is set to the predominant, typical ambient temperature
actually present in the system. Specific to functions, this parameter is
processed further by the individual device functions that are based on this
parameter value.
