Speed controller active
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
The control signals that the speed controller is closed.
The control signals that the speed controller is open. The speed controller
output is cleared.
For spindles without closed-loop position control, the interface signal can be
used as feedback for the IS "Controller enable".
MD30350 = 1.
DB380x DBX2.1 (controller enable)
DB390x DBX1.5 (position controller active)
MD30350 SIMU_AX_VDI_OUTPUT
(output of axis signals for simulation axes)
Function Manual Basic Functions S1
Current controller active
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
The control signals that the current controller is closed.
The control signals that the current controller is open. The current controller
output (including the feedforward quantities on the manipulated variable for
the voltage) is cleared.

Handwheel override active
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
The function "Handwheel override in Automatic mode" is active for the pro‐
grammed positioning axis (FDA[AXi]). Handwheel pulses for this axis affect
the programmed axis feedrate either as path definition (FDA = 0) or as ve‐
locity override (FDA > 0).
The function "Handwheel override in Automatic mode" is not active for the
programmed positioning axis (or concurrent positioning axis).
An active handwheel override is not active if:
● The positioning axis has reached the target position.
● The distance-to-go is deleted by the axis-specific interface signal
DB3200 DBX6.2 (delete distance to go).
● A RESET is performed.
