Connect the largest-capacity spindle drive unit to the final axis of the NC communication bus in
order to control the power supply unit. The spindle drive unit must be installed adjacent to the
power supply unit. In the system with servo only, a servo drive unit for controlling unbalance axis
must be installed in the same manner in the same way.

CAUTION
Two or more power supply units may be required within a single NC communication bus system if
the spindle drive unit capacity is large. The drive unit receiving power (L+, L-) from each power
supply unit must always have NC communication cable connection at the NC side of each power
supply unit. In the NC communication bus connection example below, power supply [1] cannot
supply power (L+, L-) to the 6th axis servo drive unit.
For basic connection information, refer to the MDS-DM Series Instruction Manual.

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_n o" (for the spindle axis) to th e axis that is no t
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".
