Definitions
Nominal voltage.
U
N
Minimum allowed resistance value of the brake resistor per one phase of the brake module.
R
min
Maximum resistance value of the brake resistor per one phase of the brake module.
R
max
Connect one resistor per brake chopper module phase. For example, a brake unit of frame size
2×R8i includes two brake chopper modules -> 2 × 3 resistors are needed.
