19.1.99 L_Interpolator_1
This FB interpolates a position setpoint and/or an analog value e.g. to compensate for larger bus
transmission cycles or to continue signal characteristics if data telegrams are missing.
Inputs
Outputs
Identifier
Data type
Information/possible settings
dnPhIn_p
DINT
Position setpoint
• Is interpolated and completed when signal interpolation is activated.
nPhdIn_v
INT
Angular velocity
• Is only passed through to the nPhdOut_v output.
nNIn
INT
Analog value
• Is interpolated when signal interpolation is activated.
bSpeedAct0
BOOL
Input for detecting the "Current speed is zero" status
• This status signal needs to be transmitted by the setpoint source to ensure
trouble-free operation.
TRUE The current speed is zero. The interpolator in the follow-up controller
is kept to the dnPhiIn_p input.
• This function is for instance required for referencing the axis.
Since in this case, the axis can move independently of the master
position, the follow-up controller is not allowed to intervene.
Identifier
Data type
Value/meaning
dnPhOut_p
DINT
Output of the dnPhIn_p position setpoint which, if applicable, has been interpolated
and completed
nPhdOut_v
INT
Output of the nPhdIn_v angular velocity
nNOut
INT
Output of the nNIn analog value which, if applicable, has been interpolated
bPulse
BOOL
"Input values have been accepted" status signal
TRUE The input values have been accepted during this cycle.
bSignalError
BOOL
"Signal error" status signal
• Only if signal monitoring is active ( C00950/2 = "1: On").
TRUE The number of missing data telegrams has exceeded the limit value
parameterised in C00952 .
