7.1 Protective earth
Connection of Titan Go Servo Drive and motor housing to Protective Earth (PE)
is required for
safety
reasons.
Electrical faults can electrically charge the housing of the motor or cabinet, increasing the risk of electrical
shocks. A proper connection to PE derives the charge to Earth, activating the installation safety systems (differential
protections) and protecting the users.
Moreover, a proper connection to PE prevents many of the noise problems that occur operating a servo drive.

Electromagnetic Interference Issues With Servo Drive Systems
7.1.1 Reducing EMI susceptibility
Connecting the drive PE terminals
and cold plate screws
to your system Earth and to the motor housing solves
many noise and EMI problems.
The PE drive terminals are decoupled to power ground through safety capacitors.
This provides a low impedance
preferential path for coupled common-mode noises that otherwise would be
coupled to sensitive electronics like the encoders. A good
grounding of the drive to the earth of the power
supply
is also essential for EMI reduction.
Titan Go Servo Drive provides the following earth/ground connection points, which are internally connected and
decoupled to power ground and power supply:
Cold plate is connected to PE.
A diagram of the recommended Earth wiring is shown below.
7.1.2 Earth plane reference
While some systems will not have a "real Earth" connection, use your
machine chassis
, the metallic structure of the
device or a good grounding conductive plane as your reference earth.
Some considerations for a proper earth connection are detailed next:
Switching noise can be coupled to the earth through the housing of the motor. This high-frequency noise
creates a common mode current loop between drive and motor. Although the motor housing is connected
to earth through the system chassis, its electrical connection may have a relatively high impedance and
