The golf trolley is driven by two wheels (9), the speed being regulated by the variable speed gear (5) located near the trolley handle.

Sensing devices are multiplexed to these valves to detect a number of different possible fault states relating to the variator shift valves and the variator pressure control valves.

Apparent output power of VSD (kVA

motors with an integrated variable speed drive (compact drives) whose energy performance cannot be tested independently from the variable speed drive

A variable speed drive controls the speed of the refrigerant flowing through the compressor.

The invention relates to a method for setting a speed regulating loop of a speed variator intended to control a motor connected to a lifting load.

In order to adjust the variator, a respective means for producing an axial force for adjusting a cone pulley of a cone pulley pair is provided for each cone pulley pair.

A control speed of the lambda control is greater than the maximum adaptation speed (v(admax)).

The measuring of the make-time of a dimmer is executed when additional load is connected.

The first velocity setting comprises an upper or maximum velocity setting and the second velocity setting comprises a lower or minimum velocity setting.

The variable speed drive has a component (74) that generates heat during operation of the drive and a base.

The mechanism further includes a speed adjustor (16) and control means interacting with the speed adjustor (16) in order to change the driving speed of the ringing device.

A variable speed drive powers the motor.
