4.4.1 How to Obtain the Power Supply Module Rated Output
Capability
Select a power supply module with a rated output not less than the
sum of the total continuous rated output of the spindle motors times
1.15, plus the total continuous rated output of the servo motors times
0.6.
Rated output capacity of power supply module
≥ Σ Continuous rated output of spindle motor × 1.15
+Σ Continuous rated output of servo motor × 0.6
When only spindle amplifier module is to be connected to a power
supply module, select the power supply module so that the 30-minute
rated output of the spindle motor does not exceed the rated output
capacity of the power supply module.
Rated output capacity of a power supply module ≥ 30-minute rated output of
a spindle motor
Table 4.3 lists the rated 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 continuous rated outputs
or 30-minute rated output of the spindle motors.
4.4.2 How to Obtain the Power Supply Module Maximum Output
Capability
Select the power supply module whose maximum 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 and whose acceleration time exceeds 0.3 seconds.
Maximum output of power supply module
≥ Σ Accelerating maximum output of spindle motor +
Σ Maximum acceleration-time outputs of the servo motors whose
acceleration time exceeds 0.3 seconds.
(on simultaneous acceleration/deceleration axis)
Table 4.4 lists the maximum output capacities of the power supply
modules. Tables 4.5.1(a) to (c) list the accelerating maximum outputs
of the servo motors. Tables 4.5.2(a) and (b) list the accelerating
maximum outputs of the spindle motors.
