which the autotune was carried out, this will not be allowed. If in doubt, the autotune speed is recorded in the parameter Max Spd When Autotuned,
described below.
Parameter Name No. Path Default Range Units Writable
Autotune Enable 0255 Setup::Motor Control::Autotune
Parameters::Motor Control::Autotune FALSE STOPPED
Puts the autotune feature into a state where it will carry out the autotune when the drive is started.
Autotune Mode 0256 Same as PNO 255 1 0:STATIONARY
1:ROTATING STOPPED
Selects whether the autotune is carried out on a rotating motor, or whether it just calculates from nameplate data (not the preferred
method). It may be necessary to carry out a stationary autotune if the motor is not free to rotate, for example if it is already connected
to a machine. Leakage inductance (to tune the current loop) and stator resistance may be measured when the motor is stationary, but
other parameters can only be inferred from nameplate data. Use the rotating autotune where possible.
Nameplate Mag Current 1550 Setup::Motor Control::Autotune
Parameters::Motor Control::Autotune 1.00 0.01 to 1000.00 A STOPPED
This parameter will only become visible if Autotune Mode = STATIONARY is selected.
If you select stationary autotune, you must enter the motor magnetising current into this parameter before proceeding with the
stationary autotune. If this is not known, it can be approximated from the motor rated current and the power factor, as motor current
times √(1 – PF^2).
The value of mag current entered here will be copied into the magnetising current parameter in the Induction Motor Data menu. If a
rotating autotune is run at a later date, it will be replaced with the more accurate value, and this parameter will be irrelevant.

This is only valid for induction motor autotune
Allows selected tests to be disabled (default all tests are carried out).
Each test can be individually disabled by setting to TRUE.
