1.6 Examples of Servo System Configurations
A system configuration for a three-phase main circuit power supply voltage of 400 VAC is shown in the fol-
lowing figure.
∗1. Use a 24-VDC power supply with double insulation or reinforced insulation (The power supply is not included).
∗2. The DC power supply for the 24-VDC brake is not included.
• For 200-V input voltage: LPSE-2H01-E
• For 100-V input voltage: LPDE-1H01-E
Use one of the following power supplies for 90-VDC brake. For details, contact your Yaskawa representative or the
sales department. For details, refer to Large-Capacity
Σ -V series Catalog (Manual no.: KAEP S800000 86).
∗3. For details on grounding, refer to 3.10 Noise Control and Measures for Harmonic Suppression.
∗4. Before connecting an external regenerative resistor unit, refer to 3.8 Selecting and Connecting a Regenerative Resis-
tor Unit.
∗5. For details on the dynamic brake unit, refer to 3.9 Selecting and Connecting a Dynamic Brake Unit.
