(*) These variables are from the ATV61_IO_SCAN structure (see description in relationships table below).
The inputs/outputs and the functions are quickly described. The function block is available from Schneider
End user solution Web Site.
Input description
RPM Setpoint for motor speed in Manual mode.
FbStat Starter status word. Feedback signal from I/O scanning
FbRPM ATV output speed. Feedback signal from I/O scanning
ATV_Meas Starter measures. Feedback signal from I/O scanning
The type of measure variable is dened in the ATV I/O scanner.
Output description
QCrtl Starter control word, sent to the starter via I/O scanning
QRPM ATV setpoint speed, sent to ATV via I/O scanning
