FALSE Output speed = "0".
TRUE Output speed = transformed input speed.
dnSpeedIn_s
DINT
Selection of the master speed
• At this input, the FB expects a speed in [rpm]. The machine parameters at the in-
put XAxisData are used as speed reference.
• C05165/1 indicates the master speed in the real unit of the machine.
XAxisData Machine parameters for scaling the master speed (master shaft)
• The machine parameters of a master drive can be displayed with the
FB L_SdSetAxisData
. In this case, the FB output AxisData must be connected to
this input. ( 510)
YAxisData Machine parameters for scaling the setpoint speed (tool)
• For accepting the machine parameters of the drive/motor, connect this input
with the output DI_AxisData of the SB LS_DriveInterface.
