Cables in the same cabinet (4)
For the connection cables of the options such as the parameter unit or dynamic brake option, which is arranged in the same
cabinet as the servo amplifier, use a shielded cable (shielded twisted pair cable for the parameter unit), and ground it on both
sides of the option and servo amplifier with P clips or U clips.
When the cable length is 2 m or less, ground the cable on the servo amplifier side.
Regenerative option connection cable (5)
Use a shielded twisted pair cable or twisted cable covered with shield braid for the connection cable of the regenerative
option, and ground the shield on the both sides of the option and servo amplifier with P clips or U clips. The following figure
shows the treatment when the regenerative option is installed outside the cabinet.
Input power cable (6)
Use a multiple core cable. Using a shielded input power cable increases the effect of EMC countermeasures.
Control circuit power cable (for servo amplifier) (7)
Use a vinyl wire or multiple core cable.
