Chapter 5 Methods Of Anomaly Diagnosis - Delta HES Series Instructions For Use Manual

Chapter 5 Methods of Anomaly
The Hybrid Servo Controller 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 activated and the Hybrid Servo Controller 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 Controller for
troubleshooting. The error record will be stored in the internal memory of the Hybrid Servo Controller
(up to the most recent six error messages) and can be read by the digital operation panel or
communication through parametric readout.
 Upon the occurrence of anomaly, wait for five seconds after the anomaly is resolved
before pressing the RESET key.
 For Hybrid Servo Controllers with power
power is turned off and for ten minutes for models with power
the charging indicator is off. Measure the DC voltage between terminals
which should be below DC25V before opening the machine cover and starting the
inspection.
