Installation
General precautions for installation
To ensure the best performance of the EMI filter, apart from the instruction and wiring of the
2
servo drive, refer to these precautions:
1. The servo drive and EMI filter must be mounted on the same metal plate.
2. The wiring should be as short as possible.
3. The metal plate should be well grounded.
4. It is recommended to install one servo drive with one EMI filter.
More specifications for mounting the servo drive are listed as follows:
1. EN61000-6-4 (2001)
2. EN61800-3 (2004) PDS of category C2
3. EN55011+A2 (2007) Class A Group 1
Motor cable selection and installation precautions
The selection of motor cable (refer to Chapter 3 Wiring) and installation accuracy determine the
performance of the EMI filter. Follow these precautions:
1. Use a cable that has braided shielding (the effect of double shielding is better).
2. The shield on both ends of the motor cable should be grounded with the shortest cable
length and the largest contact area.
3. Remove the protective paint on the U-shape saddle and metal plate to ensure good
contact. See the following figure.
4. Correctly connect the braided shielding of the motor cable and the metal plate: fix the
braided shielding on both ends of the motor cable with the U-shape saddle and metal plate.
See the following figure.
(1) Remove the protective paint on the U-shape saddle and metal plate to ensure good contact.
(2) U-shape saddle
(3) Well-grounded metal plate
