NOTE about servo drives:
The recommended servo drive / inverter module is designed for 1.1x the stall current. If more than double the amount is needed during
the acceleration phase, the next larger servo drive should be selected. This recommendation is only a guideline; detailed inspection of the corresponding speed/
torque characteristic curve can result in deviations of the servo drive size (larger or smaller).
NOTE about cable cross section:
The B&R motor cables with this cable cross section are produced optimally (cables stripped to the correct length) for the
ACOPOS servo drive or the recommended ACOPOS inverter module. B&R motor cables with other cable cross sections can also be used (within the specified
terminal cross section range) and can be obtained from B&R in the desired design on request. Note the type of wiring.
