Note that a diode should be installed to a DC relay, DC valve or the like. Maximum voltage: Not less than 4 times the drive voltage of

the relay or the like

Maximum current: Not less than twice the drive current of

the relay or the like

(c) Cable clamp fitting (AERSBAN -SET)

Generally, the earth of the shielded cable may only be connected to the connector's SD terminal. However, the effect can be increased by directly connecting the cable to an earth plate as shown below.

Install the earth plate near the servo amplifier for the encoder cable. Peel part of the cable sheath to expose the external conductor, and press that part against the earth plate with the cable clamp. If the cable is thin, clamp several cables in a bunch.

The clamp comes as a set with the earth plate.

Strip the cable sheath of
the clamped area.	cutter
