Motor circuit breakers are used for protecting a
motor and its supply cable against overheating
by overload. Depending on the overload level,
- they disconnect the motor from power supply
immediately in the case of a short-circuit or they
disconnect the motor if an overload has occurred
for some time.
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
A 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.
