Maximum magnetisation: The parameter permits the motor to move within the basic speed
range with reduced magnetization. With a light load, this can be used to reduce heatup of motor
and inverter. The parameter should usually be set to 100% (no reduction).
NOTE
The parameter is only effective in control type B20= 2:Vectorcontrol.
Value range in %: 50 ... 100 ... 100

Phase test & start: Writing a one starts the phase test action. It may only be used for servo
motors. A check is made to determine whether phases were mixed up when the motor was
connected, whether the number of motor poles (B10) is correct and auto-tunes the commutation
offset (B05). During the action the motor must be able to revolve freely.
The enable must be LOW at the starting point. After B40.0=1 the enable must be switched HIGH.
After the action was executed, the enable must be switched back to LOW. The result of the action
can be read after removal of the enable in B05.
During this action the cycle time is internally set to 32 ms. The switch is made when the action is
activated.
WARNING
Starting the action releases the motor brake. Since, due to the action, the motor is not sufficiently
energized, it is unable to carry any loads (e.g., in a lifting system). For this reason the action may
only be performed with motors which are not installed in a system.

Autotuning & start: Writing a one starts the Autotune motor action. It measures the resistance
(B53) and the inductivity (B52) of the motor. The drive may move during this action.
The enable must be LOW at the starting point. After B41.0=1, the enable must be switched to
HIGH. After the action is executed, the enable must be switched back to LOW. The result of the
action can be read in B52, B53 after the enable is removed.
During this action the cycle time is internally set to 32 ms. The switch is made when the action is
activated.
When an asynchronous machine (B20<64) is being used, the action also autotunes the values for
B54 leakage factor and B55 saturation coefficient.
WARNING
Starting the action releases the motor brake. Since, due to the action, the motor is not sufficiently
energized, it is unable to carry any loads (e.g., in a lifting system). For this reason the action may
only be performed with motors which are not installed in a system.
