4.3.3 How to Obtain the Power Supply Module Peak Maximum
Output Capability
Select the power supply module whose peak output capability will not
be exceeded by the total of the sum of the maximum acceleration
spindle motor outputs and the sum of the maximum acceleration
outputs of the servo motors that are accelerated simultaneously.
Power supply module peak maximum output capability
≥ Σ spindle motor maximum acceleration outputs
+ Σservo motor maximum acceleration outputs
(on simultaneously accelerated axes)
Table 4.3 lists the peak output capacities of the power supply modules.
Tables 4.5.1(a) to (c) list the continuous rated outputs of the servo
motors. Tables 4.5.2(a) and (b) list the according maximum outputs of
the spindle motors.
4.3.4 Number of Connected Servo Amplifier Modules and Spindle
Amplifier Modules
Multiple servo amplifier modules and spindle amplifier modules can
be connected to a single power supply module, provided the above
output capacity conditions are satisfied.
The table below lists the maximum number of modules which can be
connected.

CAUTION
1 When different types of servo amplifier modules are
connected, the following condition must be
satisfied:
6 ≥ Number of SVM1s × 1 + Number of VM2s × 1.5
6 ≥ Number of SVM1s × 1 + Number of SVM3s × 2
The maximum number of servo amplifier modules
that can be connected is the same when a spindle
amplifier module is not used.
2 No SVM3 is available in the 400-V input series.
