CSD7 Servo Drive (EtherCAT)
Battery
Battery
It describes the battery for absolute encoder information preservation.
When the power of servo drive is cut off, the battery memorizes the absolute position of
the load system and helps maintain it.
If the power of servo drive is cut off and discharged the battery power to lower than the
standard, the saved information in absolute encoder may be damaged.
Battery specification : 3.6V
The voltage of battery is not directly monitored from the drive but the error is checked
indirectly through the encoder. Prepare the low voltage detection circuit as needed basis.
Battery Voltage Diagnosis
The voltage monitored with encoder is displayed for servo warning and fault depending on
the following situation.
•
Servo Warning
When the voltage of battery for absolute encoder is 3.2 [V] or less, Absolute encoder
battery low voltage warning occurs. At this time, the below warning characters are displayed
in the status display mode.
Replace the battery before having ‘Battery low voltage fault for absolute encoder’ occurs
with the battery low voltage in having the warning.
