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

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_a
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 Current speed is zero.

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_a
INT
Output of the
nNIn_a
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
