⚫ In order to suppress interference as much as possible, twisted pair cables with shielded nets can
be used for power lines, encoder lines, and IO control lines, but the shielding layer must be
properly grounded ；
The shield of encoder uses metal
cable clamp connecting to the
shield of connector.
The shield of power cable uses
U-shape metal cable clamp
connecting to the PE port.

3.2.3 DC bus
The braking energy generated during motor operation will be fed back to the drive bus
capacitors, causing the drive bus voltage to rise. Under the condition that the multi-axis control
is asynchronous (part of the motor is electric, part of the motor is braked), the common DC bus
can keep the drive bus voltage more stable and realize the full utilization of energy. Note that
when using a common DC bus, each drive should still refer to Chapter 3.2 External System
Connection for normal wiring .
