8.3 Operation with frequency converter
8.3.1 Control elements
The converter operates using the following
control elements:
Encoder
• 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
2
• This converter has got a block with two switches
with two positions (Fig. 4):
• 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 ».
