2.4 Cable Specifications and Peripheral Devices242.4 Cable Specifications and Peripheral DevicesRatings and specifications for peripheral devices, as well as cable specifications for digitaltorque amplifiers are summarized in the tables below.■ Cable SpecificationsNotes: 1. Wire sizes were selected for three cables per bundle at 40°C ambient temperature with the rated current.2. Use cables with a minimum withstand voltage of 600V for main circuits.3. If cables are bundled in PVC or metal ducts, consider the reduction ratio of the allowable current.4. Use heat-resistant cable under high ambient or panel temperatures where normal vinyl cable will rapidlydeteriorate.External Terminal NameSGDGTerminalSymbolWire Size AWG [in 2 (mm 2)]01GT 04GTMain circuit power input terminals L1, L2(Single Phase)16 AWG [HIV 0.002(1.25)] 14 AWG [0.003 (2.0)]Servomotor connection terminals U, V, W 16 AWG [HIV 0.002 (1.25)]Control power supply terminals L1C, L2CControl I\O signal connector CN1 Twisted pair or shielded twisted pair wiresCore wire at least 28 AWG [0.0002 (0.12)], tinned,annealed copper twisted wiresFinished cable dimensions:maximum Φ0.63in (16mm) for CN1 and Φ0.27in(6.8mm) for CN2.PG signal connector CN2Ground terminal 14 AWG [HIV 0.003 (2.0)]Main circuit power input terminals L1, L2, L3(Three-phase) 14 AWG [HIV 0.003 (2.0)]Servomotor connection terminals U, V, WControl power supply terminals L1C, L2C 16 AWG [HIV 0.002 (1.25)]Control I\O signal connector CN1 Twisted pair or shielded twisted pair wiresCore wire at least 28 AWG [0.0002 (0.12)], tinned,annealed copper twisted wiresFinished cable dimensions: maximum Φ0.63in(16mm) for CN1 and Φ0.27in (6.8mm) for CN2.PG signal connector CN2Ground terminal 14 AWG [HIV 0.003 (2.0)]Wiring Precautions• Do not bundle or run power and signal lines together in the same duct.Keep power and signal lines at least 11.81” (30cm) apart.• Use twisted pair or shielded multi-core twisted pair wires for signal andencoder (PG) feedback lines.• The maximum lengths for signal lines are as follows:• Maximum of 9.84ft (300cm) for reference input lines.• Maximum of 65.6ft (20m) for PG feedback lines.• Use a cable with 164 ft (50m) specifications for distances over 65.6ft (20m).CAUTION |
