• Enable signal for opening a protective device (e.g. "Open door").
•
The workpiece chuck or the tool clamping device is only opened when
the spindle is stationary.
• The oscillation mode can be switched-in during gear stage change after
the spindle has been braked down to standstill.
•
The tool clamping device must have been closed before the spindle can
be accelerated.
MD36060 STANDSTILL_VELO_TOL
(maximum velocity / speed for signal "Axis / spindle stationary")
Function Manual Basic Functions S1
Position controller active
Signal(s) from axis / spindle (NCK → PLC)
Signal(s) updated: Cyclic
The control signals that the position controller is closed.
The control signals that the position controller is open.
If "controller enable" is withdrawn because of a fault or from the PLC user
program the position controller is opened and therefore the interface signal
"Position controller active" is set to a 0 signal.
Spindle without position control: Signal "Position controller active" is always
"0".
•
The IS "Position controller active" can be used as feedback signal for
the IS "Controller enable".
•
The holding brake of a vertical axis must be activated as soon as the
position control is no longer active.
•
If a spindle has been technically designed/dimensioned for the purpose,
in the part program, it can be changed-over into the closed-loop position
controlled mode as spindle or as axis (with SPCON or M70). In these
cases, the interface signal "position controller active" is set.

(output of axis signals for simulation axes)
Function Manual Basic Functions S1
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".
