SD20-G Series

The installation precautions are as follows:
1) Symmetrical shielded cable is recommended. The four-conductor shielded cable can also be used as an input
cable.
2) The motor cable and PE shielded conducting wire (twisted shielded) should be as short as possible to reduce
electromagnetic radiation and external stray current and capacitive current of the cable. If the motor cable is
over 100 meters long, an output filter or reactor is required.
3) It is recommended that all control cables be shielded.
4) The motor cables must be laid far away from other cables. The motor cables of several servo drives can be
laid side by side.
5) It is recommended that the motor cables, power input cables and control cables be laid in different ducts. To
avoid electromagnetic interference caused by rapid change of the output voltage of the servo drive, the motor
cables and other cables must not be laid side by side for a long distance.
6) If the control cable must run across the power cable, make sure they are arranged at an angle of close to 90°.
Other cables must not run across the servo drive.
7) The power input and output cables of the servo drive and weak-current signal cables (such as control cable)
should be laid vertically (if possible) rather than in parallel. The filter, servo drive and motor should be
connected to the system (machinery or appliance) properly, with spraying protection at the installation part
and conductive metal in full contact.
