Note 1:
The speed at the starting point to be adjusted around PID regulator
F226 is a zero servo time parameter, used to adjust and control the delay time given by the system
speed curve; this time is also the action time of PID regulator P0, I0, and D0 at zero servo (or zero
speed). See the following for the detailed timing sequence diagram.
Figure 8.1 Zero Servo Timing Sequence Diagram
When zero servo ends, AIO inverter gives the controller a signal with speed instruction, and
the elevator begins to accelerate.
F212, F213 and F214 are proportional (P0), integral constant (I0) and the differential constant (D0) of the
zero servo regulator. In adjustment, fist set P0 to a very small value, and have the elevator go downward
non-loaded; at this moment, the elevator shows pull-back at start. Increase the P0 value gradually, until the elevator
stops showing pull-back at start. However, if P0 is too large, the elevator may oscillate up and down at start. So in
case of obvious oscillation at start, decrease the P0 value. I0 is the integral constant of zero-speed PID regulator at
