4.1.3 IndraSize
By using the IndraSize software, drive controllers, motors and mechanic
gearboxes can be easily sized. The engineering tool covers the entire range
of Rexroth drives and motors. Calculate the characteristic curves for your ap‐
plication by using the sizing and calculation tool IndraSize: www.boschrex‐

Power wire cross section A mm²
Rated according to DIN VDE 0298-4 and laying type B2 according to DIN
IEC 60204-1 with conversion factor for Rexroth cables at 40 °C ambient
temperature.
The power wire cross section that is specified in the data sheets can vary
depending on the selected type of connection - plug or terminal box.
When selecting the power cable, refer to the specifications in chapter
8 ”Connection technique” and the documentation ”Rexroth Connection
Cables" (DOK-CONNEC-CABLE*INDRV-AU□□-□□-P).
