Position controller active
Application
example(s)
If the position control is active the axis/spindle is kept in position by the position controller.
Any brakes or clamps can thus be opened.
The interface signal:
DB31, ... DBX61.5 (position controller active)
can be used as feedback signal for the interface signal:
DB31, ... DBX2.1 (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The holding brake of a vertical axis must be activated as soon as the position control is no longer
active.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.
Special cases,
errors, ....
Special case for simulation axes (MD30350 $MA_SIMU_AX_VDI_OUTPUT = "1"):
The IS "position controller active" is also set for simulation axes as soon as MD = "1".
Corresponding to .... DB31, ... DBX2.1 (controller enable)
DB31, ... DBX1.4 (follow-up mode)
DB31, ... DBX1.5 and 1.6 (position measuring system 1 and 2)

DB31, ...
DBX61.6
Speed controller active
Edge evaluation: no Signal(s) updated: cyclic
Signal state 1 or
edge change
0 → 1
The control signals that the speed controller is closed for the axis or spindle.
Signal state 0 or
edge change
1 → 0
The control signals that the speed controller is open for the axis or spindle.
The speed controller output is cleared.
Application
example(s)
If the spindle is not under position control, the interface signal can be used as a feedback for the
interface signal:
DB31, ... DBX2.1 (controller enable).
Special cases,
errors, ....
Special case for simulation axes (MD30350 = "1"):
The interface signal:
DB31, ... DBX61.6 (speed controller active)
is also set for simulation axes as soon as:
MD30350 $MA_SIMU_AX_VDI_OUTPUT (output of the axis signals for simulation axes) = "1".
Corresponding to .... DB31, ... DBX61.5 (position controller active)
