XC2 Hardware Manual Chapter 2: Installation and Configuration
2.1.3. Minimizing Conducted, Radiated, and System Noise for
EMC/CE Compliance
NOTE: The XC2 is a component designed to be integrated with other electronics. EMC testing must be
conducted on the final product configuration.
To reduce electrical noise, observe the following motor and input power wiring techniques.
1. Use shielded cable for motor and feedback connectors. Tie the shield to the backshell at each end of
cable.
2. Physically separate motor cables from low level cables carrying encoder and IO signals.
3. Mount drives and filter components on a conductive panel. Mount line filters close to the drive to
minimize the wire length between the drive and filter. Use a line filter, such as Aerotech’s UFM-ST, on
the Motor Supply and Control Supply AC inputs.
4. Use the lowest motor voltage to reduce radiated emission.
5. Use an isolation transformer with grounded secondary to minimize the effects of high frequency PWM
amplifier currents.
6. Use a separate wire for each ground connection to the drive. Aerotech recommends that you use the
shortest possible wire length to connect to a central bus located close to the drive.
The following additional changes could be required for EMC compliance and are recommended during initial
EMC system evaluation.
1. Add a clamp-on ferrite to the feedback cable close to the drive.

2. Add a clamp-on ferrite to the Motor Supply and Control Supply wires, including the ground wire, close to
the drive.

3. Add a ferrite core to the DC input wires. Refer to Figure 2-1 and Figure 2-2 .

4. Add a ferrite core to the motor phase and ground wires close to the drive. Wrap all four wires around the
ferrite core once. Remove ferrite beads from Aerotech supplied cables if installed.

5. Install a motor filter module MFM10-1 close to the drive. The ferrite core that you added to the motor
phase and ground wires should be located between the drive and the MFM10-1.
