Trial Operation6.4.2 Soft Start Time Setting (TSFS: C1-10)6 -106.4.2 Soft Start Time Setting (T SFS : C1-10)The Inverter speed base is the time set to be taken from 0 min−1. to the rated speed (C1-26), or from therated speed setting to 0 rotations/min. The reference/time relationship is shown in the following diagram.The soft start time can be set between 0.1 and 180.0 s.The acceleration and deceleration times may be longer than the soft start time setting due to load inertia.Speed referenceRated speed (C1-26)Speed baseTime (s)(%)1000 TSFS TSFSSpeed reference and baseFig 6.3 Soft Start Time Setting6.4.3 Load Factor Meter Full Scale (LMFS : C1-18)The load factor meter displays the output ratio (in %) over the Motor rated output while the Motor is operat-ing. Set the full scale value (i.e., the percentage value over the Motor continuous rating) of the load factormeter using control constant C1-18. The setting can be between 120% and 500%.6.4.4 Zero Speed Detection Level (ZS LVL : C1-19)Use this constant to set the detection level for the zero speed signal. The standard setting is 30 min−1. Thesetting can be between 3 and 60 min−1.
