4.2 Commercial power supply
Supply commercial power to the amplifier.
(1) Power supply
(a) 200 [V] 3-phase input voltage of amplifier
Supply 200 [V] commercial power to the amplifier.
Connect it to terminals L1, L2 and L3.
• Voltage : 200/200-220-230 [V] +10%/ -15%.
• Frequency : 50/60 [Hz]
• Phase : 3-phase (main circuit power supply) / single-phase (control power supply)
(b) 100 [V] single-phase input voltage of amplifier
Supply 100 [V] commercial power to the amplifier.
Connect it to terminals L1 and L2.
• Voltage : 100 to 115 [V] +10％/ -15％
• Frequency : 50/60 [Hz]
• Phase : Single-phase (main circuit and control power supply)
(2) Power supply capacity
The power supply capacity required for each amplifier is as follows.
The power supply capacity is applied for cabling with specified cable and 20 [m] max. wiring length. If the power capacity is 500 [kVA] or
more, AC reactor for impedance matching should be provided. See 10.5 AC reactor (reactor for impedance matching).
