Issue Number: 1
The nominal output cable size assumes the motor maximum current matches that of the drive. Where a motor of reduced rating is used the cable
rating may be chosen to match that of the motor. To ensure that the motor and cable are protected against over-load, the drive must be programmed
with the correct motor rated current.
Ensure cables used suit local wiring regulations.
4.12.1 Cable type
Use 105 °C (221 °F) (UL 60/75 °C (temp rise) PVC-insulated cable with copper conductors having a suitable voltage rating, for the following power
connections:
• AC supply to external EMC filter (when used)
• AC supply (or external EMC filter) to drive
• Drive to motor
• Drive to braking resistor
Most cables have an insulating jacket between the cores and the armor or shield; these cables have a low capacitance and are recommended.
Table 4-13 Cable ratings (200 V)
The nominal cable sizes below are only a guide. The mounting and grouping of cables affects their current-carrying capacity, in some cases
smaller cables may be acceptable but in other cases a larger cable is required to avoid excessive temperature or voltage drop. Refer to
local wiring regulations for the correct size of cables.
