Check that the power supply and wiring of L1,L2 are correct.If the driver
only supports single-phase 220VAC, please do not connect it to the
380VAC power supply.
The output terminals(U,V,W ) must be connected with the servo motor
connections(U,V,W ) correspondently, otherwise the servo motor will stop
or over speed. However, by exchanging three-phase terminal cannot
cause the motor to reverse; this point is different from asynchronous motor.
Earthed wiring must be reliable with a single-point connection.
Pay attention to the correct direction of freewheel diode which is
connected with the delay at the output terminal, other can cause the output
circuit breakdown.
In order to protect the servo driver from noise interference that can cause
malfunction, please use an insulation transformer and noise filter on the
power lines.
Wiring the power lines(power supply line, main circuit lines,etc) at a
distance above 30cm from the control signal wires, do not lay them in one
conduit.
Install a non-fuse circuit breaker that can shut off the external power
supply immediately for in case of the servo driver fault.
Because there are large-capacity electrolytic capacitors inside the servo
drive, even if the power supply is cut off, there is still a high voltage in the
internal circuit. After cutting off the power supply, wait at least 5 minutes
before touching the drive and motor.
