U
Nominal voltage
N
R
Minimum allowed resistance value of the brake resistor per one phase of the brake module.
min
R
Maximum resistance value of the brake resistor per one phase of the brake module.
max
Note:
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.
No-overload use
I
Input current. Input current with R
