3.5 General System Wiring Guidelines
The following is a general reminder of the cable requirements for the DS2100 Series Servo-drives and related
equipment.
Size wire in accordance with standard wiring practice and local codes for amperage and wire length requirements.
Recommended wire sizes are given in Section 2.
Avoid close parallel routing of signal wires and power wires, both inside and outside of the control cabinet. High
voltage bus wires should be shielded and their length should be minimised.
Ensure proper chassis earths on all equipment. Terminate all individual chassis earths from power supply and servo-
drives to a single tie point, (i.e. cabinet earth bus). Keep the distance from earth bus to earth ground as short as possible.
Similarly, keep distance from servo-drive and power supply chassis earths to the tie point as short as possible. Chassis
earth should be run close to D.C. Bus wires to minimise EMI. The impedance between the earth terminal and any
accessible part of the equipment enclosure or cabinet should be less than or equal to 0.1
W
Tighten all terminal screws securely to avoid faulty operation. Torque screws to the specified values
All power connections to the DS2100 mA, A, B & C Series Servo-drives are through removable plug-in mating
connectors. Do not solder the ends of the cables to be inserted into screw clamp terminals. All power connections to the
DS2100 D are via screw terminal connections.
NOTE - Cabling and component wiring is critical in obtaining successful operation of the
system. Pay close attention to specified wiring practice, cabling information, earthing and
shielding requirements. Improper wiring can result in electrical noise generation and
unstable motor performance.
CAUTION - Shielded cable is required to be installed by the user for many external
user cable connections to the DS2100 Servo-drive. Details of areas where shielded
cable must be installed and details of earthing arrangements which must be
implemented for the shields of such cables are given in the relevant sections.
WARNING - All electrical supply wires and cables to this equipment must be installed
in conduits (cable routings) which are smooth and free from sharp edges.
WARNING – The removable plug-in mating connectors are for ease of wiring and are
not suitable for connection or dis-connection when power is applied. All dis-
connections must be made with power removed.
