2.5.4 Noise Filters, Surge Suppressors, Magnetic Conductors, and Brake Power
Supply
Note: 1. Connect a noise filter on the AC side of an AC/DC power supply.
2. Mount the surge suppressor on the magnetic conductors to prevent noise from the power supply and to
protect the contacts.
(1) Magnetic Conductors
Connect the magnetic conductors on the DC side of an AC/DC power supply. Select the magnetic conductors
according to the capacity of the power supply. If several servo system are being used at the same time, select the
magnetic conductors according to the total capacity.
(2) Brake Power Supply
The brakes of the SGMMJ and SGMAJ servomotors are 24 VDC. The 24-VDC brake power supply must be
provided by the customer. Be careful when connecting the power supply for 24 VDC brake to the local power
supply. The local power supply cannot apply the overvoltage such as surge to the output side, and the output side
may be damaged even if the voltage is applied. Never fail to use the surge suppressor.
