Husqvarna Grinder PG530 User Manual

12 

- English

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:

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).

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

Identifi es 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.

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.
