Actual signals and parameters
Description
Defines the trigger point for the drive power consumption counter. Value is
compared to parameter 2908
Megawatt hours. If parameter value is set to zero, the trigger is disabled.
Defines the actual value of the drive power consumption counter. When
parameter 2907 USER MWh TRIG has been set to a non zero value, the
counter starts. When the actual value of the counter exceeds the value
defined by parameter 2907, a maintenance notice is displayed on the panel.
Megawatt hours. Parameter is reset by setting it to zero.
Programmable protection functions
Selects how the drive reacts when an analog input signal falls below the set
minimum limit.
Protection is inactive.
The drive trips on fault AI1/AI2 LOSS and the motor coasts to stop. Fault limit
is defined by parameter 3021/3022
The drive generates alarm AI1/AI2 LOSS and sets the speed to the value
defined by parameter 1208
parameter 3021/3022 AI1/AI2 FAULT LIMIT.
WARNING! Make sure that it is safe to continue operation in case
the analog input signal is lost.
The drive generates alarm AI1/AI2 LOSS and freezes the speed to the level
the drive was operating at. The speed is determined by the average speed
over the previous 10 seconds. Alarm limit is defined by parameter
AI1/AI2 FAULT LIMIT.
WARNING! Make sure that it is safe to continue operation in case
the analog input signal is lost.
Selects how the drive reacts to a control panel communication break.
Drive trips on fault PANEL LOSS and the motor coasts to stop.
The drive generates alarm PANEL LOSS and sets the speed to the speed
defined by parameter 1208
WARNING! Make sure that it is safe to continue operation in case of
a panel communication break.
The drive generates alarm PANEL LOSS and freezes the speed to the level
the drive was operating at. The speed is determined by the average speed
over the previous 10 seconds.
WARNING! Make sure that it is safe to continue operation in case of
a panel communication break.
Selects an interface for an external fault 1 signal.
Not selected
External fault indication through digital input DI1. 1: Fault trip (EXT FAULT 1).
Motor coasts to stop. 0: No external fault.
