Measures against the noise

The example of noise measures of the tracking system is shown in the following.
Please implement the measures against the noise if needed in the power supply periphery section for the
encoders which prepared of the customer.
1) Please insert AC line filter (recommendation: MXB-1210-33 * Densei-Lambda) in the AC input side cable
of the power supply for the encoders.
2) Please insert the ferrite core (recommendation: E04SR301334 * SEIWA ELECTRIC MFG.) in the DC
output side cable of the power supply for the encoders.
3) Please connect the power supply case for the encoders to the installation operator control panel, connect
the earth wire to grounding or the case, and insert the ferrite core (recommendation: E04SR301334 *
SEIWA ELECTRIC MFG.).
