Lenze Smart Motor m300 - Brake Resistors

Brake resistors
The Lenze Smart Motor can be braked in a guided manner along a ramp. If large amounts of
regenerave energy are produced during braking, they must be absorbed by a brake resistor.
In addion to a brake resistor (10 W) mounted inside the terminal box, another brake resistor
(20 W) can also be connected externally alongside the terminal box via the terminal X4.
These brake resistors are mounted and parameterized at the factory.
NOTICE
Do not fall below the minimally connectable brake resistance of 180 Ω at the terminal "X4".
If an external brake is used, the power can be increased from 20 W to max. 40 W if the
medium speed is > 1000 rpm (arithmec mean of the process speeds in relaon to the motor
speed, without standsll).
