NOTE
1 The total length of the cable between the CNC and amplifier
and that between the amplifier and motor shall not exceed
50m.
2 As the current feedback lines (IRn and ISn), use the middle
twisted pair of the recommended cable. If any other pair is
used, abnormal noise or oscillation may occur.
3 The servo interface of the Series 0i is type B. Use a servo
unit which supports the type–B interface. When using a
servo unit which supports both the type–A and type–B
interfaces, select the type–B interface. For details, refer to
the manual supplied with the servo unit. If the interface
setting is incorrect, a servo alarm (AL401 V READY OFF)
will be issued.
