4.11 566 Drive overload mode ENUM Light duty 1 2 ERWZ VS
Setting of the overload that can be supplied by the drive, depending on the application.
1 Heavy duty
2
Light duty
Set Heavy duty when a large overload is requested: the drive can supply 180% of the rated current for 0.5
seconds and 150% for 1 minute every 5 minutes.
Select Light duty to enable the drive to deliver a current of 110% of the rated current for 1 minute every 5
minutes.

4.12 568 Switching freq mode ENUM Costant 0 1 ERWZS VS
Setting of the switching frequency operating mode when drive overload is set in Heavy duty. The factory
switching frequency setting is 4 kHz for motors between 2.2 kW and 37 kW (the factory switching frequency
setting for smaller drives is 8kHz); this value may result in increased noise. Setting a higher switching fre-
quency will increase drive losses and thus increase the heatsink temperature, but it will also reduce noise. To
combine the advantages of both settings, with the ADV drive the heatsink temperature can be controlled by
reducing the switching frequency if it increases.
0 Costant
1 Variable
If set to Costant the switching frequency is fixed and is set using the Switching frequency parameter, ac-
cording to the size of the drive. If the selected switching frequency value is higher than the default value, the
output current of the drive is derated.
If set to Variable the switching frequency is set to 8kHz and controlled by the temperature of the drive heat-
sink and by the output frequency. If the heatsink temperature exceeds a set threshold (which depends on the
size of the drive) or falls to below 5Hz ± 1Hz, the switching frequency is automatically reduced to 4kHz, to
prevent derating of the output current. The switching frequency is reduced in a single step. With this setting
the switching frequency value selected in the Switching frequency parameter is ineffective .

4.13 570 Password UINT32 0 0 99999 ERW VS
You can enter a password to protect the parameters from unauthorized tampering: the password can consist
of a combination of a maximum of any 5 figures that can be selected by the user. All parameters are locked,
except this one and Save parameters .
After entering the password, press the E key once to enter it into the memory and again to enable it (= Ena-
bled is displayed to indicate that the password is enabled).
So that the password remains valid even after switching the unit off and then switching it back on, save it us-
ing the Save parameters command.
When the password is enabled any attempts to modify a parameter are blocked and the Password enabled
message is displayed.
To disable the password, enter the Password parameter ( 572 ) in the DRIVE CONFIG menu .
Check that the password is enabled (
Enabled
), press
E
and enter the combination of figures that make up
the password.
Press E again. A message is displayed telling you the password is no longer enabled (
Disabled ).
To make sure the password continues to be disabled even after switching the unit off and then switching it
back on, save this configuration using the Save parameters command.
When an incorrect password is entered, the Password wrong message is displayed.

4.14 572 Application key UINT32 0 0 4294967295 ERW VS
This parameter can be used to enter the key for enabling the PLC application.
You may need to enter a key to definitively enable some PLC applications. Please contact Gefran for details
