Outputs
Parameters
bUnwind
BOOL
Selection of the enabled change or direction
•Only when bUnidirect = TRUE
FALSE Clockwise rotation (Cw)
TRUE Counter-clockwise rotation (Ccw)
nSetDiameter_a
DINT
Selection of an initial value/external diameter signal
• Scaling: 16384 ≡ maximum diameter (wMaxDiameter)
• The value is accepted by setting bLoadDiameter to TRUE.
bLoadDiameter
BOOL
Accept initial value nSetDiameter_a
• This input has a higher priority than the bHoldDinput.
TRUE Accept the value at nSetDiameter_a.
