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. Note:
No-overload use
