Typical resistor cable sizes
This table gives copper cable types. Cable sizing is based on max. 9 cables laid on a cable
ladder side by side, three ladder type trays one on top of the other, ambient temperature
30 °C, PVC insulation, surface temperature 70 °C and 90 °C (EN 60204-1 and IEC
60364-5-2/2001). For other conditions, size the cables according to local safety regulations,
appropriate input voltage and the load current of the drive.

￭ Maximum cable length
The maximum cable length of the resistor cable(s) is 300 m (984 ft). Keep the cable as short
as possible in order to minimize the EMC emissions and stress on chopper IGBTs. The
longer the cable the higher the EMC emissions. The longer the cable the higher the inductive
load and voltage peaks over the IGBT semiconductors of the brake chopper.
