 Stop!

ƒ The supply of Lenze controllers of the 82xx and 93xx series is not

permitted.

ƒ If synchronous motors with a high centrifugal mass are used, a

considerable amount of energy can be fed back into the DC bus.

Please take this into account when dimensioning the brake

resistor.

ƒ If the total cable length is > 20 m, install an axis module or a capacitor

module directly at the power supply module.

ƒ Design the ±U

cables twisted and as short as possible. Ensure

short−circuit−proof routing!

ƒ Cable length (module « module) > 30 cm: install shielded ±U

cables.
