Description
Specification
Circuit Breaker
Uses to protect the power supply
line and cut off the circuit when an
overcurrent occurs.
The minimum rated current of the circuit
breaker depends on the Drive model.

ED3S-A5A*, 01A*, -02A*, -04A*: 10A

ED3S-08A*, -10A*: 25A

ED3S-15A*: 35A

ED3S-20A*: 55A

ED3S-30A*: 70A
Noise Filter
Used to prevent external noise
interference from the power supply.
The rated current is 10A or 20A.
External
Regenerative
Resistor
When the busbar capacitance is
insufficient, remove the short
wiring between B2 and B3, and
connect an external regenerative
resistor between B1 and B2.
(1)
The minimum value of the regenerative
resistor depends on the Drive model.

ED3S-A5A*, 01A*, -02A*, -04A*: 50Ω

ED3S-08A*, -10A*: 25Ω

ED3S-15A*, -20A*, -30A*: 10Ω
(1): ED3S-A5*, ED3S-01*, ED3S-02* and ED3S-04* must connect an external regenerative resistor.
