4.1.3 Connections and Wiring Notes
• Ensure the grounding wires are securely connected. Wire with a cross section of more than 2.0mm
2
is recommended.
• Grounding method must be single point grounding.
• Ensure V+ and V- are correctly wired, and voltage supplies are within the specified range.
• Auxiliary power V+ connects to drive AUX connector, auxiliary power V- connects to drive V-.
• Ensure U/V/W is wired following the order of RED/YELLOW/BLUE.
• An isolation transformer or EMI filter is recommended on drive’s power supply to ensure the drive’s safety and improve its anti-
interference level.
• Set up emergency stop circuitry to switch off the power supply when a fault occurs.
• DO NOT touch the drive or motor’s connector terminals for at least 5 minutes after the drive and motor have been powered off. There
are electrical charge components in the circuitry which discharge slowly.
• Install the encoder cables in a separate conduit from the motor power cables to avoid signal noise. Separate the conduits by at least
30cm (11.8 inches).
• Use multi-stranded twisted-pair wires or multi-core shielded-pair wires for the encoder feedback cables.
• The maximum length of the signal input/output cable should be no more 5 meters, and the encoder (PG) feedback cable no more
than 15 meters.
