Wire And Terminal Screw Sizes; Control Circuit; Main Circuit - YASKAWA VS-606V7 Series Instruction Manual

(10) Voltage drop should be considered when determining wire size.
Voltage drop can be calculated using the following equation:
Phase-to phase voltage drop (V)
= √  3 wire resistance (Ω/km) × wiring distance (m) × current (A) × 10
Select a wire size so that voltage drop will be less than 2% of the
normal rated voltage.
