Estimating System Inertia
The HPV 600 software can be used to calculate
the inertia of the entire elevator, which is used
for accurate tuning of the speed regulator.
The following is a step-by-step procedure for
using the HPV 600 to estimate the elevator
system inertia.
Using the Software to Estimate the System’s
Inertia
With a balanced car, run the car at 100%
contract speed from top floor to the bottom floor
then back to the top floor.
Observe the EST INERTIA under DISPLAY
MENU - ELEVATOR DATA D1 for both the
down and up direction.
Average the two values and enter the DRIVE A1
parameter.
