18.1.138 L_PhiIntegrator_1
This FB evaluates a speed with a gearbox factor and adds them in an integrator.
• The integrator value is output as 16-bit value and 32-bit value.
• An overflow of the prevailing output is signalled.
• The integrator can be loaded and initialised (e.g. with a touch probe signal).
Inputs
Identifier
Data type
Information/possible settings
nSpeedAdd_v
INT
Additive speed
nSet_v
INT
Speed input (angular difference)
wGearNum
WORD
Gearbox factor (numerator)
wGearDenom
WORD
Gearbox factor (denominator)
• When wGearDenom = 0, it is internally calculated with 1.
dnTPPosition_p
DINT
Initialisation value
bTPReceived
BOOL
Initialise integrator
FALSETRUE Initialise integrator
bReset
BOOL
Reset integrator
TRUE Reset integrator
• The integrator is not integrated.
bLoad
BOOL
Load integrator
TRUE Load integrator with dnLoadVal_p
• The integrator is not integrated.
• The bInitDone output is reset to FALSE with a delay of one call
cycle after bLoad is reset to FALSE and a subsequent FALSE/TRUE
edge to bTPReceived.
dnLoadVal_p
DINT
Value the integrator is to be loaded with.
