ABB ACS320 User Manual

Actual signals and parameters 203
 Group 30: Fault functions
This group defines situations that the drive should recognize as potential faults and
defines how the drive should respond if the fault is detected.
2907
USER MWh TRIG
0.0 … 6553.5 MWh 0.1 MWh 0.0
Defines the trigger point for the drive power consumption counter. Value is compared
to the value of parameter 2908 USER MWh ACT.
• Megawatt hours. If parameter value is set to zero, the trigger is disabled.
0.0 = NOT SEL
2908
USER MWh ACT
0.0 … 6553.5 MWh 0.1 MWh 0.0
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.

Code Description Range Resolution Default S
3001
AI<MIN FUNCTION
0…3 1 0
Defines the drive response if the analog input (AI) signal drops below the fault limits
and 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, Group 41: Process PID set 2 or Group 42: Ext / Trim PID) and
the corresponding PID controller is active.
3021 AI1 FAULT LIMIT and 3022 AI2 FAULT LIMIT set the minimum limits.
0 = NOT SEL – No response.
1 = FAULT – Displays a fault (0007 AI1 LOSS or 0008 AI2 LOSS) and the drive coasts
to a stop.
2 = CONST SP 7 – Displays a warning (2006 AI1 LOSS or 2007 AI2 LOSS) and sets
speed using 1208 CONST SPEED 7.
3 = LAST SPEED – Displays a warning (2006 AI1 LOSS or 2007 AI2 LOSS) and sets
speed using the last operating level. This value is the average speed over the last
10 seconds.
WARNING! If you select CONST SP7 or LAST SPEED, make sure that continued
operation is safe when the analog input signal is lost.
