Auto-tune test 1: Basic control parameters
This test measures the basic control parameters without moving the motor.
1. A stationary test is performed to measure
Stator Resistance
(05.017),
Transient Inductance
(05.024),
Maximum Deadtime Compensation
(05.059) and
Current At Maximum Deadtime Compensation
(05.060).
Auto-tune test 2: Basic control and improved performance parameters
This test measures the parameters for improved performance by rotating the motor.
1. Auto-tune test 1 is performed.
2. A rotating test is performed in which the motor is accelerated with the currently selected ramps up to a frequency of
Motor Rated Frequency
(05.006)
x 2/3, and the frequency is maintained at that level for 4 seconds.
Stator Inductance
(05.025) is measured and this value is used in conjunction with
other motor parameters to calculate
Motor Rated Power Factor
(05.010). The motor should be unloaded for this test.

Dynamic V to F mode is intended for applications where power loss should be kept to a minimum under low load conditions, but dynamic performance is not
important. The reduction in power loss under low load conditions is achieved by increasing the rated frequency used to derive the frequency to voltage
characteristic of the drive with reduced load. If
Flux Optimisation Select, Dynamic V To F Select
(05.013) = 0 then
Motor Rated Frequency
(05.006) is used
directly to define the output voltage characteristic. If
Flux Optimisation Select, Dynamic V To F Select
(05.013) = 1 then a modified value of motor rated
frequency is used:
Motor rated frequency =
Motor Rated Frequency
(05.006) x [2 - |
Percentage Load
(04.020)| / 70.0%]
For loads > 70%
Motor Rated Frequency
(05.006) is used directly.
