OMNUC G5-series (Pulse-train Input Type) AC Servomotors and Servo Drives User’s Manual
Precautions for Correct UsePrecautions for Correct Use
• The above example shows an example of connecting a Servo Drive with 3-phase 200 VAC
main circuit power supply inputs. Use a power supply and power cables that meet the power
supply specifications of the Servo Drive.
• Note that incorrect connection of signal lines may cause damage to the Servo Drive and
connected units.
• Leave unused signal wires disconnected and open.
• Use mode 2 for origin search.
• Recommended surge-absorbing diode: RU2 (Sanken Electric Co., Ltd.) or equivalent
• Connect signal lines so that the servo can be turned ON and OFF with the RUN signal.
