1.4 Precautions during wiring
✎Do not connect the three-phase power supply to the output terminals U, V, W of the servo
drive, otherwise it may damage the device or cause a fire;
✎Please connect the output U, V, W of the servo drive and the U, V, W of the servo motor
directly. Do not use the electromagnetic contactor during the connection, otherwise it may cause
abnormal operation or malfunction of the device;
✎When the DO output terminals are connected to the relay, please pay attention to the polarity
of the freewheeling diode, otherwise the drive may be damaged and the signal can not be output
normally;
✎Please fix the power terminal and the motor terminal firmly, otherwise it may cause a fire
hazard;
✎Do not connect the 220V servo unit directly to the 380V power supply;
✎Do not pass the power line and signal line through the same pipe or bundle them together.
When wiring, the power line and signal line should be separated by more than 30cm;
✎Use twisted-pair shielded cables for signal cables and encoder cables, and the shielding layer
should be grounded at both ends;
✎The wiring length of the signal input line is recommended to be within 3M, and the wiring
length of the encoder is recommended to be within 15M;
✎When using in the following places, please take adequate shielding measures.
✎When interference occurs due to static electricity.
✎Places where strong electric or magnetic fields are generated;
✎Places where there may be radiation;
✎When checking the status, please make sure that the CHARGE indicator is off.
1.5 Precautions during operation
✎During trial operation, in order to prevent accidents, please run the servo motor without load
(not connected to the drive shaft), otherwise it may cause injury.
✎When the servo motor is running, do not touch its rotating part, otherwise it may cause injury.
✎Be sure to set the correct moment of inertia ratio, otherwise it may cause vibration.
✎When it is installed on the supporting machine and starts to run, please set the user
parameters in accordance with the machine in advance. If you start running without setting
parameters, it may cause the machine to lose control or malfunction.
✎When installing on the supporting machinery and starting to run, please put the servo motor in
a state where it can be stopped in an emergency at any time, otherwise you may get injured.
✎When using a servo motor on a vertical axis, please install a safety device to prevent the
workpiece from falling under alarm, overtravel, etc. states. In addition, please set the servo lock
stop setting when the overtravel occurs, otherwise the workpiece may fall in the overtravel state.
✎Since extreme user parameter adjustments and setting changes will cause the servo system to
become unstable, please never make settings, otherwise it may cause injury.
