Motor / motor actuation
Function:
The motor is controlled (open-loop and closed-loop) by phase control.
The actual speed value of the tachogenerator signal is compared with
the required value of the electronics module. The direction of rotation
is changed by two deenergised reversing relays. An integrated
protector in the motor winding disconnects the motor in the event of
an overload. The control does not disconnect the motor with
a tachogenerator fault but continues trying to restart the motor.
A motor fault is displayed only at the end of the programme. In these
appliances is not necessary an aditional relais for reaching 1400 min-
1. The following speeds apply to the washing machine with empty

If an unbalanced load is detected, the speed is reduced in the final
spin cycle as follows:

Before each spin speed acceleration, the imbalance is scanned for
20 seconds at 100min-1 (A). The imbalance is scanned up to 15x (up
to 2x for wool).
If there is a large imbalance, the spin cycle is terminated at approx.
100 min-1.
