structure
when Trip 0 occurred and the relevant trip in hours and minutes. The maximum time difference that can be stored is 600 hours. If this time is
exceeded the value stored is 600.00.
If the powered-up clock is used as the source for this function all the times in the log are reset to zero at power-up because they were related to the
time since the drive was powered-up last time. If the runtime clock is used the times are saved at power-down and then retained when the drive
powers up again. If Pr 6.28, which defines the clock source, is changed by the user the whole trip and trip time logs are cleared. It should be noted
that the powered-up time can be modified by the user at any time. If this is done the values in the trip time log remain unchanged until a trip occurs.
The new values put in the log for earlier trips (Trip 1 to 9) will become the time difference between the value of the power-up clock when the trip
occurred and the value of the powered-up clock when the latest trip occurred. It is possible that this time difference may be negative, in which case
the value will be zero.
10.52 - 10.61 Trip Masks
Bit SP
Coding
Range 0 to 217
Default 0
Update rate Background read
The user can mask some of the trips from tripping the drive. The trip can be completely masked (do nothing in the event of the selected trip) by setting
the trip number into the parameter.
10.62 - 10.71 Stop on Trip Masks
Bit SP
Coding
1
Default 0
Update rate Background read
The trip can be made to stop the drive then trip (non-important trip) by enabling the associated bit parameter.
Trips that cannot be masked are: UU, AOC, PS, O.SPd, PS.10V, PS.24V, FOC, O.ht1, O.ht2, O.ht3, EEF and HF17 to HF29.
Example 1
The user wants the drive not to trip when there is no field current. Enter 16 into 10.52 to achieve this.
Example 2
The user wants the drive to stop and then trip when there is no field current. Enter 16 into Pr 10.52 and set Pr 10.62 to 1 to achieve this.
10.72 Trip Mask Active
Bit SP
Coding
1
Range 0 to 1
Default 0
Update rate Background write
Set to 1 when a trip is being masked.
10.73 Bridge Active
Bit SP
Coding
Range 0 to 2
Default 0
Update rate Background write
This parameter will indicate which bridge is on.
"__ "No bridge
"_1 "Bridge 1 active
"2_ "Bridge 2 active
Where _ is a blank.
