Definitions
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
1
I
Output current. This is indicated in the type designation label as 3x the value with R
2
in this table.
P
Maximum continuous braking power per brake unit.
cont.max
P
S
Apparent power.
n
Cyclic load (1 min / 5 min)
I
Peak brake current (DC) per brake chopper module phase.
max
I
Input current.
dc
I
Total rms DC current per brake unit phase during a period of 1 minute with braking power
