Starting time 

The length of the starting time determines the time during which the motor voltage is 

increased from the parameterized starting voltage to the supply voltage. This has an 

influence on the motor's acceleration moment, which drives the load during the ramp-up 

operation. A longer starting time has a smaller acceleration moment throughout the motor 

ramp-up. The latter is therefore longer and smoother. The length of the starting time should 

be selected so that the motor reaches its rated speed within this period. If the time selected 

is too short, in other words if the starting time ends before the motor has started up 

successfully, a very high starting current that equals the direct starting current at the same 

speed occurs at this instant. The soft starter can, in this case, switch itself off via the internal 

overload protection function and go into fault mode. 

Maximum starting time 

The "Maximum starting time" parameter can be used to determine the time after which the 

drive must have completed its run-up. If the drive is not operating under rated service 

conditions after the specified interval has expired, the startup procedure is interrupted and a 

fault message is generated. 

Internal run-up recognition 

The soft starter features internal run-up recognition. If the device recognizes a completed 

motor run-up, the internal bypass contacts close and the thyristors are bridged. If this run-up 

recognition is performed before the set starting time is completed, the ramp is canceled and 

the motor voltage is immediately increased to 100 % of the line voltage before the internal 

bypass contacts are closed.
