Note
1.Select cables with more than 85% shielding coverage in the diagram.
Input/Output signal cable
2. Please install the device in the control cabinet. The device should be installed on the same metal
backplane with good electrical conductivity in the cabinet.
(1) Reactor
To suppress the higher harmonic currents at the input power side, connect a reactor to the power input end of the driver.
Figure 3-6 shows how to install a reactor.
The reactor and the driver must be installed in the same metal backplane (electric galvanized steel) and the metal backplane
must be well grounded.
(2) EMC noise filter
To ensure that the product meets EMC standards, install an EMC noise filter at the power input terminal near the servo driver.
For details about the noise filter model, see Section 3.2 External systems connection.
The length of the cable between the output of the noise filter and the input power supply of the driver should be less than
30cm.
The driver and filter are installed in the same metal backplane and the metal backplane is well grounded;
Do not lay the input and output cables of the filter in the same slot or bind them together.
The PE of the filter and the PE of the driver are single-point grounded. Do not connect PE in series to the ground pile.

(3)Shielded layer
I
nput and output signal cables, power cables, encoder cables and communication cables please use shielded cables.
The shield of the encoder is clamped to the connector metal housing using metal cables.
The shielding layer near the driver side of the power cable is locked to the driver PE screw using the U-shaped metal clip
delivered with the product.
If the power line and the encoder are not direct outlet solutions, it is necessary to peel the sheath layer at both ends of the
connector and connect the shielded layer of the cable to the metal plate using a 360-degree shield clamp.
