Absolute System
When you make your own cable for 17-bit absolute encoder
When you make your own cable for 17-bit absolute encoder, connect the optional battery for absolute
encoder, DV0P2060 or DV0P2990 as per the wiring diagram below. Connector of the battery for absolute
encoder shall be provided by customer as well.
<Cautions>
Install and fix the battery securely. If the installation and fixing of the battery is not appropriate, it may cause
the wire breakdown or damage of the battery.
Refer to the instruction manual of the battery for handling the battery.
• Installation Place
1) Indoors, where the products are not subjected to rain or direct sun beam.
2) Where the products are not subjected to corrosive atmospheres such as hydrogen sulfide, sulfurous
acid, chlorine, ammonia, chloric gas, sulfuric gas, acid, alkaline and salt and so on, and are free from
splash of inflammable gas, grinding oil, oil mist, iron powder or chips and etc.
3) Well-ventilated and humid and dust-free place.
4) Vibration-free place

Setup (Initialization) of Absolute Encoder
Execute the setup of absolute encoder in the following cases.
• Initial setup of the machine
• When absolute system down error protection (alarm No. 40) occurs
• When the encoder cable is pulled out
A home position can be set in the two ways
below.
• Normal homing
(Refer to “Homing Operation” on page 114.)
Execute one of the eight types of homing op-
erations and store that position in EEPROM
as the position. Positioning is performed
based on the stored position as the home
position even after the power supply reset.
• Define “0” position of absolute encoder as a home position
Clear an absolute encoder so that a machine home position and the “0” position of absolute encoder can
match with each other. By using a data of the absolute encoder after the power supply reset, positioning is
performed based on the “0” position of absolute encoder as the home position.
The absolute encoder is cleared through a console or “PANATERM
®
”. A multi-turn data only is cleared by
clearing the absolute encoder.
