2.1 Comparison of Standard Connection Diagrams
WARNING
Insulate the connections of the power supply terminals. Failure to do so may
cause electric shock.
Note
Always connect a magnetic contactor between the main circuit power supply and
L1/L2/L3 of the converter unit in order to configure a power supply shut-off on the
power supply side of the converter unit. If a magnetic contactor is not connected,
continuous flow of a large current may cause a fire when the converter unit or
servo amplifier malfunctions.
Generate a fault signal and shut off the power supply. Not doing so may cause a
fire when a regenerative transistor malfunctions or the like may overheat the
regenerative resistor.
To avoid a malfunction of the servo motor, connect the wires to the correct phase
terminals (U/V/W) of the drive unit and the servo motor.
Do not connect the servo motor directly to the 3-phase 200 V power supply or the
3-phase 400 V power supply. Otherwise a malfunction may be caused.
Do not switch the motor power cables while currents are applied to the motor.
Doing so may cause an abnormal operation or a malfunction.
POINT
When using an external dynamic brake, refer to the Servo Amplifier Instruction
Manual.
