One of the questions I often hear is “why does the machine have a battery?” Each generation of OKUMA machine tool controls has different reasons. Most are for holding software or parameters, but some are for keeping the date and time or for shutting down the machine. Unlike other machine tools, Okuma doesn’t require a battery for the encoder system. The four battery systems used in our controls are listed below as well as why we use them.

OSP P300A, P300, P200A, P200, AND P100 CONTROLS

• Coin Battery – This battery is on the back of the panel PC and is there to hold your BIOS settings just like on any computer. Most notably it holds the time and date.

• UPS Battery – Okuma includes this battery to ensure that if power is lost, the control will have power to shut down Windows properly. If you’ve ever unplugged your desktop computer and restarted in safe mode, you’ll understand what happens when a computer is turned off incorrectly and restarted.

OSP E100 CONTROL

• Battery Pack – While the system software is stored on the flash drive on this control, the parameters are stored in CMOS memory. This type of memory has to have a battery to hold memory when the power is off.

OSP U100, 7000, 5020

• Battery Pack – These controls all have the same type of CMOS memory holding all the software as well as the parameters for the machine.
