The menu tree illustrated on this page outlines the
important menu options that provide useful information for
monitoring and diagnostic purposes when using the
machine.
As can be seen on the menu tree to the right, when the
machine is turned on, the variable speed drives or
frequency converters are set to display the Output
Frequency to the motor (a zero value will register when
the machine is in stand-by mode).
The Output Frequency page also falls under the Monitor
Menu.
It can be seen from the left hand column, the two primary
menus important to the operator are the Monitor Menu
and Fault History menu.
OPERATING

Menus and information they provide
The following menu items/screens can be used by an
electrician or qualified person to assist in trouble spotting
operations related to the frequency drives.
OUTPUT FREQUENCY (Monitor Menu)
This screen tells the operator the frequency the motor is
running at when the machine is in operation. The value for
output frequency should be constant when the machine is
running. If there is a fluctuation in output frequency when
the machine is running, generally this indicates the motor
is running at or near the limit of its programmed current
limit. The current limits (predetermined and set by
Husqvarna Constructions Products) are as follows:
• Combined large and small motor - 14 amps. (Single-
phase)
• Combined large and small motor - 16 amps. (3 phase)
If there is a fluctuation in output frequency when the
machine is in operation, it is advisable to check the motor
current as well. This can be found by pressing the UP
arrow on the keypad 3 times. For trouble free operation
concerning current issues, it is best to keep output current
at or around 12-13 amps. The current draw of the motor
can be reduced by reducing the speed of the motor using
the speed dial on the control panel near the handle bars.
MOTOR CURRENT (Monitor Menu)
This screen displays the current draw of the
corresponding motor (i.e. large variable speed drive/
frequency converter monitors function of large motor,
small variable speed drive/frequency converter monitors
function of small motor) when the motor is running.
