Power From 8510 Drive To The 1327A Series Motor
The motor power output terminals are located at the bottom of the drive as
shown in Figure 7.3. Motor current requirements and wire size are
dependent on the specific motor type. Table 8.F defines the drive output
current requirements when used with the various motor catalog numbers.
Wire sizes are selected per NFPA-79 and IEC-204 for wires in a cable or
raceway and are based on 75
°
C wire (70
°
C for IEC-204).
The motor fan should be wired to the motor fan power terminals on the
bottom of the drive (see Figure 7.3 for terminal locations). The terminals in
both the drive and motor use M4 screws. The motor fan current ranges
from 0.3A in the smallest motor to 1.2A in the largest motor. The power
output terminals are fused in the drive with 5A fuses. A #20
AWG/0.50 mm
2 wire is adequate for the motor fan wiring.
