·57·Chapter 7 Detailed Explanations of Functional Parameters1: LockedYou can lock the parameter by P118 to prevent unexpected changeof the inverter setup.When P118 is valid, all the other parameters except P100 (mainfrequency setting) cannot be changed.7-3 Parameters of basic applicationsP200 Start mode selection Initial value : 0Setting range 0-1 Unit 1Explanation 0: Start at start frequency1: Tracing startThere are two start modes for S900 E series inverter. You canchoose from the two by setup of parameter P200 and the conditionof machinery.0: Start at start frequencyMost loads do not have special requirement in start. Inverter outputfrom the start frequency.1: Tracing startTracing start is application for start after fault reset or instantaneouspower failure. Using tracing start function, inverter can automaticallydetect the rotation speed and rotation direction of motor, the outputthe starting frequency and voltage accordingly.Motor speedFrequency converteroutput frequencyRunning commandAttention: when inverter starts in tracing start mode, inverter willhave speed tracing in the sequence of high to low frequency.
