2.1.1.3 Connecting with MDS-SVJ3/SPJ3 Series
Connect the NC and the drive units by the optical communication cables. The bending radius
CAUTION
must be within 50mm.
Axis Nos. are determined by the rotary switch for setting the axis No. (Refer to the MDS-SVJ3/
SPJ3 Series Instruction Manual.) The axis No. has no relation to the order for connecting to

The optical communication cable up to 5m can be used in G396 series, and up to 20m in G380 series.
2.1.2 Setting up without Connecting to the Motor/ Drive unit
When connecting the motor or drive unit after setting up the system, set the axis data beforehand to enable the operation
without the motor or drive unit. The following shows the procedures.
Setting up without Connecting to the Motor
The axis detach function can be used for servo axis. The detach function cannot be used for spindle.
(1) Set the drive unit rotary switch and "#1021 mcp_no" for the axis that is not connected to the motor.
(2) Set "1" to the parameter "#1070 axoff" for the axis that is not connected to the motor.
(3) Do (a) or (b).
(a) Set "1" to parameter "#8201 AX. RELEASE" for the axis that is not connected to the motor.
(b) Turn ON the control axis detach signal (Y780) for the axis that is not connected to the motor.
Setting up without Connecting to the Drive unit
Set the following parameters.
(1) Set "#1021 mcp_no" (for the servo axis) or "#3031 smcp_no" (for the spindle axis) to the axis that is not connected
to the drive unit.
(2) Set the following parameters to the axis that is not connected to the drive unit.
For the servo axis: Set "1" to "#2018 no_srv".
For the spindle axis: Set "0" to "#3024 sout".
After connecting to the drive unit, make sure to set "#2018 no_srv" to "0" and "#3024 sout" to "1".
