5-3 Resolution for electromagnetic noise and induction noise

5-4 Environment and facilities for installation

The hybrid servo drive is capable of displaying warning messages such as over voltage, low voltage, and
over current and equipped with the protection function. Once any malfunction occurs, the protection
function will be enabled and the hybrid servo drive will stops its input, followed by the action of the anomaly
connection point and stopping of the servo oil pump. Please refer to the cause and resolution that
corresponds to the error message displayed by the hybrid servo drive for troubleshooting. The error record
will be stored in the internal memory of the hybrid servo drive (up to the last six error messages) and can
be read by the digital keypad or communication through parametric readout.
 Upon the occurrence of anomaly, wait for five seconds after the anomaly is resolved
before pressing the RESET key.
 Verify that the power indicator is off before opening the machine cover and starting
the inspection.
