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
G
cables twisted and as short as possible. Ensure
short−circuit−proof routing!
ƒ Cable length (module « module) > 30 cm: install shielded ±U
G
cables.
