Unit
Motor protection, in particular self-ventilation
motors, is improved via the
%
which can be set as a percentage of the rated
frequency.
Synchronization to a rotating drive is useful in
some applications such as pumps and fans or
after acknowledgment of an error switch-off. If
-
synchronization to the motor speed is not
possible, the function is quit and a fault message
is issued.
Actual value parameters
Unit
Effective output current (motor current) of the
frequency inverter calculated from the measurement
in the three motor phases.
V Output voltage of frequency inverter modulated
depending on the operating point of the motor
kW Calculated power of the asynchronous motor at the
current operating point. Product of output voltage,
current and cosine phi
1/min Speed of the asynchronous machine calculated using
the machine model and the current load point.
Hz The current output frequency of the frequency
inverter or actual frequency of the drive calculated
from the machine model.
- The cause of the error-switch-off and the
corresponding error key are displayed. The current
error is used for error diagnosis.
- If a critical condition is detected, this condition is
indicated by the field WARN. The warning status can
be displayed via parameter 269.
- An application-specific warning can be read. For
detailed functions, refer to Operating Instructions.
