Static
overload [846] Drive overload limit in static states (at a constant speed in a positive
direction).

Overload occurs if the quantity Load [854] (page 22) exceeds this value for a period longer
than Static overload period [849] (page 104). This parameter is in the limit autodetection
mode set automatically by the converter.
Static
overload
period [849]
Period during which the quantity Load [854] (page 22) value has to be
higher than the static overload limit, so the OPS switch will switch on.

Overload turn
off [847] Load limit to end the Overload state in the backward movement at
constant speed.

After the Overload occurs, the START Command is blocked in the positive direction.
Overload expires if during the backward movement at constant speed, the Load [854] (page
22) value drops under the the value defined by this parameter and this condition lasts longer
than the defined period Overload period turn off [850] (page 104).
Overload
period turn off
[850]
Period during which the Load [854] (page 22) quantity has to be lower
than the overload stop limit, so the OPS switch will switch off.

0,01 s ÷

OPS reset
[858]
The OPS reset command will be active if at least one of the selected
binary inputs or logical blocks will be active.
This command is used as an Overload Protection Switch turn off condition
in case it switched on. It can be necessary during reviews or inspections of
the technological device and should be activated with high caution.

DYNAMIC LIFT (DL)
Group of parameters number [1068]
Setting the parameters of the Dynamic lift function.

Name [ID] Description Def.
DL on/off [1069]
Turning on / off the dynamic lift (DL) function. During the ramp-up in the positive
direction, frequency stops on DL frequency [1073] (page 105) for the time of
DL measurement period [1070] (page 104) to settle the quantity Load [854]
(page 22) and calculation of the new speed restriction. If the load settles in the
interval between the values DL minimal load [1072] (page 104) and DL
maximal load [1071] (page 104), then the speed restriction of the lift-up is
converted linearly between the values DL frequency [1073] (page 105) and
Max. frequency [111] (page 69).
Turned
off
Turned off Dynamic lift is inactive.
Turned on Dynamic lift is active.
DL measurement
period [1070] Period of measurement of the static load on the frequency DL frequency [1073]
(page 105).
1,00 s
0,01 s ÷ 320,00 s This time is used to settle the quantity Load [854] (page 22).
DL maximal load
[1071] The upper load limit, above which the maximum frequency is not further
reduced. 100,0
%
0,0 % ÷ 1000,0 %
If the lift will be loaded to the value of this parameter or higher, its maximal speed will
be restricted to the value of DL frequency [1073] (page 105).
DL minimal load
[1072]
The lower load limit, below which the drive operates at maximum frequency. 50,0 %
0,0 % ÷ 1000,0 %
If the lift will be loaded to the value of this parameter or lower, its maximal speed will be
restricted to the value Max. frequency [111] (page 69).
