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
Maximum current: Not less than twice the drive current of
(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.
Srip the cable sheath of
athe clamped area.
