3-2) Servo amplifier
Supply commercial power shown in Chapter 11 to the amplifier.
Do not supply commercial power to the servomotor. If attempted, the motor will be broken.
(1) Commercial power supply
n
3-phase 200V series
Supply 200V commercial power to the servo amplifier. Connect the power cables to the L1, L2 and
L3 terminals.
Voltage: 200 / 200 to 230 V, -15 to +10%
Frequency: 50/60Hz
No. of phases: 3 (Single-phase 200V can be supplied to servo amplifiers with 400W or smaller
capacities.)
Use a step-down transformer to supply power from the 400V system. If the voltage is supplied
directly, the servo amplifier will be broken.
n
Single-phase 100V series
Supply 100V commercial power to the servo amplifier. Connect the power cables to the L1 and L2
terminals.
Voltage: 100 to 115V, -15 to +10%
Frequency: 50/60Hz
No. of phases: Single
Use a step-down transformer to supply power from the 200V system. If the voltage is supplied
directly, the servo amplifier will be broken.
