248 Actual signals and parameters
2907 USER MWh
TRIG
Defines the trigger point for the drive power consumption
counter. Value is compared to parameter
2908 USER MWh
ACT value.
0.0 MWh
0.0…
6553.5 MWh Megawatt hours. If parameter value is set to zero, the trigger
is disabled. 1 =
0.1 MWh
2908 USER MWh
ACT
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.
0.0 MWh
00.0…
6553.5 MWh Megawatt hours. Parameter is reset by setting it to zero. 1 =
0.1 MWh
30 FAULT
FUNCTIONS
Programmable protection functions
3001 AI<MIN
FUNCTION
Defines the drive response if the analog input (AI) signal
drops below the fault limits and AI is used
• as the active reference source (group
11 REFERENCE
SELECT )
• as the process or external PID controllers' feedback or
setpoint source (group 40 PROCESS PID SET 1 ,
41 PROCESS PID SET 2 or 42 EXT / TRIM PID ) and the
corresponding PID controller is active.
3021 AI1 FAULT LIMIT and 3022 AI2 FAULT LIMIT set the
fault limits.
NOT SEL
NOT SEL Protection is inactive. 0
FAULT The drive trips on fault AI1 LOSS ( 0007 ) / AI2 LOSS ( 0008 )
and the motor coasts to stop. Fault limit is defined by
parameter
3021 AI1 FAULT LIMIT / 3022 AI2 FAULT LIMIT .
1
CONST SP 7 The drive generates alarm AI1 LOSS ( 2006 ) / AI2 LOSS
( 2007 ) and sets the speed to the value defined by
parameter 1208 CONST SPEED 7 . Alarm limit is defined by
parameter 3021 AI1 FAULT LIMIT / 3022 AI2 FAULT LIMIT .
WARNING! Make sure that it is safe to continue
operation in case the analog input signal is lost.
2
LAST SPEED The drive generates alarm AI1 LOSS ( 2006 ) / AI2 LOSS
( 2007 ) 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
3021 AI1 FAULT LIMIT / 3022 AI2 FAULT
LIMIT .
WARNING! Make sure that it is safe to continue
operation in case the analog input signal is lost.
