Function sets whether the drive is part of the winding line or an accessory. In normal run sets which way power flows while the line is up to speed — that’s what the symmetry calculation uses.

Resistor tol. +%

Absorbed elsewhere is the share of unwind regen the rewind and other motoring axes soak up during the stop. Leave it at 0 for anything safety-related — on an E-stop or web break the rewind torque reference is gone and the resistor takes the lot.

Provisional These are indicative figures only, for single-core copper clipped direct at 30 °C ambient with no grouping. They are not a substitute for a BS 7671 calculation. Replace them with your own table before this goes anywhere near a drawing — every value is editable and saves with the config.
