structure
10.32 External trip
Bit SP
Coding
1
Default 0
Update rate Background read
If this flag is set to one then the drive will trip (Et). If an external trip function is required, a digital input should be programmed to control this bit.
10.33 Drive reset
Bit SP
Coding
1
Default 0
Update rate Background read
A zero to one change in this parameter will cause a drive reset. If a drive reset terminal is required on the drive the required terminal must be
programmed to control this bit.
10.34 No. of auto-reset attempts
Bit SP
Coding
Range 0 to 5
Default 0
Update rate Background read
10.35 Auto-reset delay
Bit SP
Coding
Range 0.0 to 25.0 s
Default 1.0
Update rate Background read
If Pr 10.34 is set to zero then no auto reset attempts are made. Any other value will cause the drive to automatically reset following a trip for the
number of times programmed. Pr 10.35 defines the time between the trip and the auto reset. The reset count is only incremented when the trip is the
same as the previous trip, otherwise it is reset to 0. When the reset count reaches the programmed value, any further trip of the same value will not
cause an auto-reset. If there has been no trip for 5 minutes then the reset count is cleared. Auto reset will not occur on Et, EEF or HFxx trips. When a
manual reset occurs the auto reset counter is reset to zero.
10.36 Hold drive OK until last attempt
Bit SP
Coding
1
Default 0
Update rate Background read
If this parameter is 0 then Pr 10.01 (Drive OK is cleared every time the drive trips regardless of any auto-reset that may occur. When this parameter is
set the 'Drive OK' indication is not cleared on a trip if an auto-reset is going to occur.
10.38 User trip
Bit SP
Coding
Range 0 to 255
Default 0
Update rate Background read
When a value other than zero is written to the user trip parameter the actions described in the following table are performed. The drive immediately
writes the value back to zero. If the value is not included in the table a trip is initiated with the same trip number as the value provided the drive is not
already tripped.
