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!
