Variable speed drives/frequency converters

Variable speed drives/ frequency converters

Each Husqvarna PG 530 is equipped with 1 variable speed drive or frequency converter. This unit is incor- porated into the machine for the following reasons:

1. Functional

Manipulate incoming power to enable increase/ decrease in speed & direction change.

Regulate current and voltage supply to the motors to ensure motors run at optimum levels (e.g. torque boost).

2.Protection/Diagnostic Protection

Monitors incoming power to ensure suitability for machine and application being performed.

Controls current being drawn by motors to ensure motors are running within safe operational limits (to prevent damage to motor).

Monitors load on machine to ensure the grinder is not being overloaded thus offering protection for belt, bearings and other internal components.

Protects motors from faulty power supply (e.g. run- ning on 2 phases).

Diagnostic

Identifies electrical faults with the machine and registers fault code.

Has monitoring menus that help isolate cause of potential electrical faults.

Monitoring menus also enable operator to gauge how hard machine is working. Whilst it is not essen- tial for an operator to intimately know every feature of the variable speed drives or frequency convert- ers, it is useful to be familiar with both the fault codes as well as some of the monitoring menus.

Keypad/Display

Each variable speed drive or frequency converter has a keypad which will appear as illustrated on the right when the machine has power connected to it.
