Chapter 7 Detailed Explanations of Functional Parameters
1: Locked
You can lock the parameter by P118 to prevent unexpected change
of the inverter setup.
When P118 is valid, all the other parameters except P100 (main
frequency setting) cannot be changed.

Explanation
0: Start at start frequency
1: Tracing start
There are two start modes for S900 E series inverter. You can
choose from the two by setup of parameter P200 and the condition
of machinery.
0: Start at start frequency
Most loads do not have special requirement in start. Inverter output
from the start frequency.
1: Tracing start
Tracing start is application for start after fault reset or instantaneous
power failure. Using tracing start function, inverter can automatically
detect the rotation speed and rotation direction of motor, the output
the starting frequency and voltage accordingly.
Motor speed
Frequency converter
output frequency
Running command
Attention: when inverter starts in tracing start mode, inverter will
have speed tracing in the sequence of high to low frequency.
