Calculate Model
When a Calculate test is run, the drive uses motor nameplate data to estimate
the motor’s Rated Flux Current, Stator Resistance (Rs), Stator Leakage
Reactance (X1) and Rotor Leakage Reactance (X2). The drive also calculates the
rated slip speed based on rated speed and rated frequency. No measurements
are taken when using the Calculate test.
Static Motor Test
Use the Static test if the motor shaft cannot rotate or if it is already coupled to
the load. Only tests that do not create motor movement are run. During this
test, the Stator Resistance (Rs), Stator Leakage Reactance (X1), and Rotor
Leakage Reactance (X2) values are measured during a series of static tests. The
Rated Flux Current is estimated, since measurement of this value requires
motor movement. The drive also calculates the rated slip speed based on rated
speed and rated frequency.
