Precautions in using a battery for absolute encoder

An error arises from the absolute encoder when a battery voltage drop occurs.

The voltage drop occurs due to the life span of a battery or voltage delay.

(1) The life span of a battery may become short depending on ambient environment.

(2) Lithium batteries have a transient minimum voltage effect (voltage delay phenomenon), in which a voltage drop

may occur temporarily when discharge starts. For this reason, the batteries should be refreshed when used.

Before using our optional battery unit DV0P2990, connect the connector with lead

wires to the battery as shown in the right figure and leave it for about 5 minutes.

And then disconnect the connector from the CN601, and install it to the servo driver.

If using another battery, we recommend that you also refresh the battery. For

refreshing a battery, consult with the manufacturer of the battery.

We recommend that control power be turned on/off once a day.

 If used incorrectly, batteries may cause troubles such as corrosion due to leakage

and hazards such as explosion. So, observe the following rules:

[1] Insert a battery correctly without confusing + and - terminals.

[2] If a battery used for a long time or no longer used is left inside equipment, a trouble such as leakage may occur.

Replace such a battery as soon as possible. (As a standard, we recommend replacing batteries every 2 years.)

• The battery electrolyte is highly corrosive. It not only corrodes surrounding parts, but it also causes hazards

such as a short-circuit due to its conductivity. Replace batteries periodically.

[3] Do not disassemble batteries or throw them into fire.

• Do not disassemble the battery because it is very dangerous if a splash of the contents comes into an eye.

Also, do not throw the battery into fire or heat it because it may burst, causing hazards.

[4] Do not short-circuit the battery or remove its tube.

• If the battery + and - terminals are connected together with a conductive material such as a metal, a large

current flows, not only weakening the battery, but also generating excessive heat, resulting in a burst to cause

hazards.

[5] Never attempt to charge the battery because it is not rechargeable.

 Disposal of old batteries after replacement may be restricted by local governments. Dispose of batteries following

such a restriction.

 Air transportation

Application for approval of hazardous material air transportation is required (for both passenger and cargo

airplanes). (UN packing is required.)

When you ask for air transportation, you are requested to submit necessary documents (parameter sheets and

MSDS etc.). In this case, make a request to us through a dealer you purchased from.

 UN packing

Consult with your transport company.
