overload (page 32)". Changing the nature of the converter load in the Operation mode
[23] (page 48) parameter resets the parameter value to the production value for the
specified load type and the specified converter type. By setting this value to higher than
factory setting, it allows converter to feed permanently higher current, but it decreases
short-term overload factor.
5
The value depends on the inverter power line. See installation manual.
Operation mode
[23] Selection of the converter load operation mode. Threshold current for
specific operation modes is factory preset. Constant
load
Constant load
Loading mode for dynamically varying loads, which have constant character of the
torque to the motor frequency. The drive allows higher short-term overload and lower
permanent load. For example: cranes, mills, conveyors, machines...
Variable load
Loading mode for static loads, which have an exponentially growing character of the
torque to the motor frequency. The converter allows lower short-term overload and a
higher permanent load. For example : Pumps, Fans, Generators, ...
Initialization time
[1154]
This time extends the initialization time. During the initialization time, start
is not possible and the faults are not evaluated. Parameter serves for
delaying the response time for slower control systems.

Password [548]
Setting the user password for access to the device settings. Password
needs to be entered when entering the converter settings.

**** ÷ **** Protects the converter settings against reconfiguration by unauthorized persons.
DST Time shift
[770] Determines whether the time of the converter is only in the normal time, or
it is changed when needed to normal or daylight saving time.

Converter
unblocking [1007]
Parameter for entering the password to unlock the converter from the trial
period mode to operation mode. For unblocking the converter, please
contact the supplier of frequency converter or device in which the converter
is used, and ask for the conditions for termination of trial operation.

Sine filter (SF)
[237]
Presence of sine filter at the converters output. Not present
Not present SF is not connected to the converter outputs.
Present
SF is connected to the converter outputs, the lower limit of switching frequency is
increased and the dynamics of controllers in vector control mode is reduced.
