Precautions when using the battery for the absolute encoder
If the battery voltage drops, an error occurs in the absolute encoder.
Voltage drop is caused by either the end of the battery life or a voltage delay.
[1] Note that the battery life is shortened depending on surrounding environmental conditions.
[2] A lithium battery has the minimum transient voltage (voltage delay phenomenon). Voltage may drop
temporarily when the battery starts discharging current. Therefore, it is necessary to refresh the battery
before using it.
<When using the battery for the first time>
If you use battery unit DV0P2990 (built-in battery: ER6V
3.6V made by TOSHIBA LIFESTYLE PRODUCTS &
SERVICES), which is an optional item of Panasonic,
connect the connector with lead wire to CN601 as shown in
the right figure and set it aside for five minutes.
Then, disconnect the connector from CN601 and attach it to
the servo driver.
Even when a battery is prepared by the customer, it is
recommended to perform refreshing before using it. For the
refreshing procedure, consult with the corresponding battery
manufacturer.
<After mounting the battery unit>
It is recommended to perform turning ON/OFF of the control power supply approx. once in a day.
Incorrect use of the battery can cause troubles such as corrosion of the product due to leakage from the
battery or risks such as breakage of the battery. Therefore, be sure to observe the following.
[1] Make sure that the directions of the positive and negative electrodes are correct.
[2] If the battery that has been used for long periods or the battery that cannot be used any more is kept set in
the device, troubles such as leakage may occur. Replace it with a new one promptly. (As a guide, it is
recommended to replace the battery every two years.)
• The electrolytic solution of the battery is not only highly corrosive, which corrodes peripheral parts, but
also conductive, which can cause short circuiting. Periodical replacement is needed.
[3] Do not dismantle the battery and do not put it into a fire.
• Do not attempt to disassemble the battery due to the extreme risks presented were its contents to spray out and
get into eyes. It may explode if subjected to fire or heated.
[4] Do not short circuit the battery and do not peel the battery tube.
• If a metal or the like touches the positive or negative electrode terminal of the battery, large current is
applied at a time, which weakens the battery.
Further, heavy heat generation may occur, resulting in bursting, which is dangerous.
[5] This battery cannot be charged. Do not charge the battery.
Disposal of the used battery after replacement is regulated by some municipalities. Dispose of the battery
according to the regulations of each municipality.
Air transportation
At the time of transportation by aircraft (both passenger airplane and cargo airplane), it is necessary to make
an application with regard to hazardous materials. (UN packaging is required.)
When requesting air transportation, it is required to submit necessary documents (such as a parameter sheet
and SDS) to the transport company. Please make the request for it via the distributor.
UN packaging
For details, contact each transport company.
