■
Surge killer (recommended)
Use of a surge killer is recommended for AC relay, magnetic contactor or the like near the servo amplifier. Use the following
surge killer or equivalent.
Ex.
CR-50500 (Okaya Electric Industries)
Note that a diode should be installed to a DC relay or the like.
Maximum voltage: Not less than four times the drive voltage of the relay or the like
Maximum current: Not less than two times the drive current of the relay or the like

Cable clamp fitting AERSBAN-_SET
Generally, connecting the grounding wire of the shielded wire to the SD terminal of the connector provides a sufficient effect.
However, the effect can be increased when the shielded wire is connected directly to the ground plate as shown below.
Install the ground plate near the servo amplifier for the encoder cable. Peel part of the cable insulator to expose the external
conductor, and press that part against the ground plate with the cable clamp. If the cable is thin, clamp several cables in a
bunch.
The cable clamp comes as a set with the grounding plate.
