General data
6
1)
If the ramp-down function "Combined braking" is selected, no braking
contactor is required.
A braking contactor must be additionally used if the "DC braking" function
is selected (for type
, see table
).
For applications with greater centrifugal mass (
J
Load
>
J
Motor
), the function
"DC braking" is recommended.
2)
Additional auxiliary relay K4:
LZS:RT4A4T30
(3RW44 soft starter with rated control supply voltage 230 V AC),
LZS:RT4A4S15
(3RW44 soft starter with rated control supply voltage 115 V AC),
3)
The type of coordination "1" refers to soft starters in combination with the
stipulated protective device (motor starter protector/fuse), not to any
additional components in the feeder.
