Battery Appearance
Note: This Battery is not available on the retail market. Order the Battery from Yaskawa Controls Co., Ltd.
(The model number is JZSP-BA01.)
•
The CPU Module comes with one Battery. The Battery is not connected when the Module is
delivered.
•
The Battery can provide backup power for the memory for a total power OFF time of 1 year.
However, this depends on the actual operating conditions, such as the ambient temperature.
•
When the total power OFF times reaches 1 year, the voltage of the Battery will drop, and the
BAT indicator on the CPU Module will light. When this occurs, always replace the Battery with a
new one within two weeks.
Delayed replacement of the Battery will result in loss of the data stored in the memory of the
CPU Module.
•
The Battery is warranted for 5 years.
