hello everyone,

I am trying now to sort out the electrical part... and cannot find information on the current ratings of cable sizes.

I will buy drag chains and flexible screened cables from Igus and don't know what size to chose for the cables. I know that thicker is safer but thick cables need bigger bending radius and I don't have to much space. I want to go with EasyChain series E14 with 38 or 48 mm bending radius.

My stepper motors are rated at 4A/phase. Will I be safe with 0.75mm˛ wires? Or should I go with 1mm˛? Or even 1.5mm˛? The longest cable will have 4.5m.

The spindle will be a 2.2KW chinese. Is 1.5mm˛ fine or should go 2.5mm˛? Will be 5.5m long.

Thanks.
