Adjustment
Input the inductance phase based on a Y-connection. Motor constants for a delta
connection should be converted being divided by
3
.
8. Motor no-load (excitation) current I
0
(H023 or H033)
Input excitation or no-load current. This can be obtained from motor specification
sheets provided by the manufacturer. If safe and feasible, it can also be measured
using a current clamp by running the motor with no load at base speed.
9. Motor inertia J (H024 or H034)
In the beginning, input approximately 6 times the inertia value of motor itself. For
further adjustment, refer to
Section 4.4
