6.6.1 Monitoring Check
– Final Peak Torque
User Interface:
Parameters: Fatal , Monitoring buffer , FTH (High level), FTL (Low level)
Function: This function checks that the Peak Torque is within limits FTH and FTL . The final torque is
the highest torque value found in the monitor buffer. The limits FTH and FTL are both
optional. Leaving them blank disables the check but the result value is still calculated and
reported.
Unless
Fatal is checked a value outside the specified limits is considered to be a repairable
error. If a value cannot be calculated and at least one limit is specified the check is always
considered
Fatal . This is for example the case if the buffer is empty when evaluating.
Monitoring buffer selects which monitoring buffer the check should use.
