(4) Internal Circuits
Open or close the circuit for the brake’s power supply so that is switched on the AC side.
When switching on the DC side, install a surge protector near the brake coil to prevent damage to the brake coil
from voltage surges due to DC-side switching.
(a) Internal Circuit for 200 VAC
Brake Power Supply Model: LPSE-2H01
(b) Internal Circuit for 100 VAC
Brake Power Supply Model: LPDE-1H01
4.4.6 External Regenerative Resistor
When the regenerative energy exceeds the capacity of the SERVOPACK, install an external regenerative resistor.
The regenerative resistor must be purchased separately by customers. Refer to the table below for selecting the
regenerative resistor. Refer to 5.5 Connecting Regenerative Resistors for the connection.
