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.
M-II
Molded-case
circuit breaker
(MCCB)
Protects the power
supply line by shutting
the circuit OFF when
overcurrent is
detected.
Noise filter
Used to eliminate
external noise from
the power line.
100/200 VAC
Molded-case circuit breaker
(MCCB)
Protects the motor fan by shutting
the circuit OFF when overcurrent
is detected.
∗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.
Use one of the following power supplies for 90-VDC brake.
• For 200-V input voltage: LPSE-2H01-E
• For 100-V input voltage: LPDE-1H01-E
For details, refer to Large-Capacity
∗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.
∗6. For connection to the option module, refer to the manual of the command option module to be connected.
