Instruction Manual of 

-S3 Inverter for Elevator

 

Function codes C03 to C10 correspond to P and I values of the PI adjuster at different 
stages during operation (see Figure 7.7). Comfort during elevator operation may be 
increased through adjustments to C03 to C10 at different stages. Function codes C11 and 
C12 are used for frequency switching between stages (see Figure 7.8). 

The structure of PI adjuster for speed loop is shown in the following figure. 

 

Increase in P may enhance the dynamic response capability of the system. However, too 
high P may lead to system vibration. The impact of P on feedback tracing is shown in the 
following figure:   

 

P and feedback tracing 

Increase in I may quicken the dynamic response of the system. When there is over-tuning 
or too slow system response, I may be increased. However, too high I may also lead to 
system vibration. The following figure shows the impact of I on feedback speed.
