8.3 Operation with frequency converter

8.3.1 Control elements

The converter operates using the following
control elements:
Encoder (Fig. A5, item 5)
• The selection of a new parameter is done only
with a simple rotation, « + » on right and « - »
on left.
• A short impulse on the encoder validates this
new setting.
Switches
ON
1 2 3 4
• This converter has got a block with two switches
with two positions each (Fig. A1, item 1):
• Switch 1 allows to change the « OPERATION »
mode [switch 1->OFF] to « SERVICE » mode
[switch 1->ON] and vice versa. The « OPERA-
TION » position allows the selected mode to run
and hinders the access to parameters input (nor-
mal operating). The « SERVICE » position is used
to enter the parameters of the different opera-
tions.
• Switch 2 is for activating or deactivating the
« Access lock », see chapter 8.5.3.
• The switch 3 is not used.
• The switch 4 is not used.

• The arborescence of the menu allows to call the
functions of the converter. A number is attrib-
uted to every menu and submenu.

of a same menu level
(example 4000->5000).
• Any blinking elements (value, menu number,
symbol or icon) allow the choice of a new value,
a new menu number or a new function.
