1) If the ramp-down function "Combined braking" is selected, no braking contactor is required.
If the ramp-down function "DC braking" is selected, a braking contactor must also be used (see table for type).
For applications with large centrifugal masses (J
Load
> J
Motor
) we recommend the function "DC braking".
2) Additional auxiliary relay K4:
LZX:RT4A4T30
(3RW44 soft starter with rated control supply voltage 230 V AC),
