3.3 HOW TO OBTAIN A POWER SUPPLY CAPACITY
- Output capacity -
The output capacity is the sum of the total spindle motor
continuous output rating multiplied by a coefficient (1.15) and
the servo motor continous output rating multiplied by a
coefficient (0.6).
-Power supply capacity-
SVPM*-5.5i
Power supply capacity (kVA) = output capacity (kW) × 1.64
SVPM*-11i
Power supply capacity (kVA) = output capacity (kW) × 1.55
SVPM*-15i
Power supply capacity (kVA) = output capacity (kW) × 1.47
[How to obtain the input current so units to be installed at the
input section can be selected]
Obtain the SVPM input current, using the following expression.
Use it as a reference value in selecting a circuit breaker, magnetic
contactor, and power cable.
