Note 1. Backup battery for absolute encoders (2.8 to 4.5 V).
Note 2. A backup battery for absolute encoders is not required for motors with incremental encod-
ers.
Note 3. Connect a backup battery for an absolute encoder to either the Connector-Terminal Block
Conversion Unit or to the battery cable for absolute encoder backup (with battery), but not
to both.
Note 4. Secure the backup battery for an absolute encoder with cable clips with double-sided tape
or a similar means.
Note 5. The XB contact is used to turn the electromagnetic brake ON and OFF.
Note 6. Do not wire unused terminals.
Note 7. Allocate BKIR (brake interlock) to CN1-1.
2-6-2 Motor Cable Specifications
The motor cable is used to connect the Servo Driver and Servomotor. Select the appropriate cable
for the Servomotor. The maximum distance between Servo Driver and Servomotor is 50 m.
Note Use a Robot Cable if the cable needs to bend.
Bend Resistance of Robot Cables
●
Robot Cables use wire that has a bending life of 20 million times when used at the minimum bending
radius (R) or greater under the following conditions.
Note 1. The bending resistance data was compiled under test conditions and must be used as a
guide only. An extra margin must always be allowed.
Note 2. The life expectancy is the number of uses without cracks or damage to the sheath that would
affect performance while current is applied to the wire conductor. This value does not apply
to cut shield strands.
Note 3. Note: If Robot Cables are used at a bending radius smaller than the minimum bending radi-
us, mechanical malfunctions, ground faults, and other problems may occur due to insulation
breakdown. Contact your OMRON representative if you need to use a Robot Cable with a
bending radius smaller than the minimum bending radius.
