However, by exchanging three-phase terminal cannot cause the motor to reverse; this point
is different with 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 cables(power supply , main circuit ,etc) at a distance over 30cm away
from the control signal cables, do not lay them together.
 Install a non-fuse circuit breaker that can shut off the external power supply immediately
for in case of the servo driver fault.

 Must use a twisted pair wire cable for the encoder signal wiring. If the encoder
signal cable is too long(＞20m), in which the encoder power supply can be
insufficient, may use multi wires or thick wire for the power supply wiring.
