System Configuration Diagram

The following diagram shows an example of a basic servo drive system configuration.
Power supply
Three-phase 200 VAC
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.
Magnetic contactor
Turns the servo
ON and OFF.
Install a surge
absorber.
Regenerative
resistor
200 VAC
DC brake power supply
Used for a servomotor with
a brake.
Brake relay
Turns the brake power
supply ON and OFF.
∗1. Use a 24-VDC power supply. (Not included.)
If using a 90-VDC power supply for a brake, however, use one of the following power supplies.
• For 200-V input voltage: LPSE-2H01-E
• For 100-V input voltage: LPDE-1H01-E
For details, refer to
∗2. Before connecting an external regenerative resistor to the SERVOPACK, refer to the User's Manual, Design and
Maintenance for your SERVOPACK.
Note: The connections and wiring of the power supply of the main circuit and that of the controls differ in accordance with
the SERVOPACK to be used. For details, refer to the User's Manual, Design and Maintenance for your SERVO-
PACK.
