ID
Description
OPS on/off
841
Activation or deactivation of the electronic OPS switch function.
OPS mode
842
Activating the overload switch modes.
The method of calculating the value „Load“: Lifting functions
Load. signal
843
Selection of the parameter, that will be used as calculation source
for the displayed value „Overload“.
Example of variable selection, which is a measure of the drive load.
100% Load
844
It is used to conversion to relative units. Value of the selected load
signal (ID 843) that equals 100% of the load.
Load filter
851
First row filter, that is used for noise or short peaks of the selected
load signal (ID 843) reduction.
Conditions of "Overload"
appearance and disappearance
:
Time after the start
852
Insensitivity period of the OPS after the drive start.
Dynamic overload
845
Drive overload limit in dynamic states (when accelerating in positive
direction).
Dynamic overload
period
848
Period during which the load value has to be higher than the
dynamic overload limit, so the overload switch will switch on.
Static overload
846
Drive overload limit in static states (at a constant speed in a positive
direction).
Static overload
period
849
Period during which the load value has to be higher than the static
overload limit, so the overload switch will switch on.
Overload turn off
847
Load limit to end the Overload in the backward movement at
constant speed.
Overload period
turn on
850
Period during which the load value has to be lower than the overload
stop limit, so the overload switch will switch off.
Blocking signal of „Overload“:
OPS reset source
572
This command blocks or switches off the OPS switch.
Numeric or bit signal can be selected.
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.
