(3) Fabricating encoder cables
POINT
The encoder cables should be fabricated by the customer. When fabricating the
cable, prepare the following parts (a) or (b), and fabricate it according to the wiring
diagram in (c).
Fabricate the encoder cable to be 50m or shorter between the servo amplifier and
the direct drive motor.
To configure the absolute position detection system by using the direct drive motor,
the battery unit (MR-BTCASE MR-BAT 8) and the absolute position storage unit
MR-BTAS01 are required.
For the absolute position detection system, refer to chapter 12.
Replacing battery unit (MR-BTCASE MR-BAT 8) should be during control circuit
power supply on.
Replacing the unit during control circuit power supply off will cause Absolute
position erased alarm (25.1).
