Open loop Rotating autotune: Basic control and improved performance
Stage 1 of the Rotating autotune is to carry out the Static autotune in Open loop as described in section 7.3.1
Stage 2 a rotating autotune test is performed in which the motor is accelerated with the selected ramps up to a frequency of

conjunction with other motor parameters to calculate

Table 7-7 lists the parameters required for Open loop motor control indicating which should be set by the user and which can be measured with an
autotune.

RFC- A Rotating autotune: Basic control and improved performance
This test measures the parameters for improved performance by rotating the motor.
Stage 1 of the Rotating autotune is to carry out the Static autotune in RFC-A, refer to section 7.3.1
Stage 2 a rotating autotune test is performed in which the motor is accelerated with the selected ramps up to a frequency of
A21
(
B06
) x

/

, and the frequency is maintained at that level for 40 seconds. The

B35
) is measured, and this value is used
in conjunction with other motor parameters to calculate the Motor rated power factor.
The motor should be unloaded for this test. Table 7-8 lists the parameters required for RFC-A motor control indicating which should be set by the user
and which can be measured with an autotune.
