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.

Information/possible settings
Data type
Position setpoint
• Is interpolated and completed when signal interpolation is activated.
DINT
Angular velocity
• Is only passed through to the nPhdOut_v output.
INT
Analog value
• Is interpolated when signal interpolation is activated.
INT
Input for detecting the "Current speed is zero" status
• This status signal needs to be transmitted by the setpoint source to ensure
BOOL
trouble-free operation.
TRUE Current speed is zero.
Value/meaning
Data type
Output of the dnPhIn_p position setpoint which, if applicable, has been interpolated
and completed
DINT
Output of the nPhdIn_v angular velocity
INT
Output of the nNIn_a analog value which, if applicable, has been interpolated
INT
"Input values have been accepted" status signal
BOOL
TRUE The input values have been accepted during this cycle.
"Signal error" status signal
• Only if signal monitoring is active
BOOL
TRUE The number of missing data telegrams has exceeded the limit value
parameterised in C00952.
