(Notes)
1. The total length of the cable should be less than
30m.
(Note 2)
2. The motor side connections after the 3rd axis
have been omitted.
3. Securely connect the shielded cable to the plate
(grounding plate) in the connector.
4. Connect an MDS-A-BT* when the servo
amplifier detector uses an absolute encoder.
5. Do not mistake the orientation of the diode.
The amplifier will fail and signals will not be
output if it is connected with the wrong
orientation.
