Control function soft starter
Description
Soft starters function according to the phase angle control principle. You can specify soft
starting and soft run-down using a settable voltage ramp. This function only applies to soft
starters.
The figure below illustrates the principle:
Figure 3-2
Termination of soft run-down (regenerative run-down)
Note
Soft run-down is only meaningful if the motor does not run down regeneratively (moving
load). If soft run-down is nevertheless activated via parameterization, the motor starter
terminates soft run-down and switches the motor off. The brake output is switched off
depending on the set parameters.
