Detailed Description
2.1 Various interface signals and functions (A2)
DB31, ...
DBX61.6
Speed controller active
Edge evaluation: no
Signal state 1 or The control signals that the speed controller is closed for the axis or spindle.
edge change
0 → 1
Signal state 0 or The control signals that the speed controller is open for the axis or spindle.
edge change
The speed controller output is cleared.
1 → 0
Application If the spindle is not under position control, the interface signal can be used as a feedback for the
example(s) interface signal:
DB31, ... DBX2.1 (controller enable).
Special cases, Special case for simulation axes (MD30350 = "1"):
errors, .... 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)
DB31, ...
DBX61.7 Current controller active
Edge evaluation: no
Signal state 1 or The control signals that the current controller is closed for the axis or spindle.
edge change
0 → 1
Signal state 0 or The control signals that the current controller for the axis or spindle is open.
edge change
The current controller output (including the feedforward quantities on the manipulated variable for
1 → 0
the voltage) is cleared.
Corresponding to .... DB31, ... DBX61.5 (position controller active)
DB31, ... DBX61.6 (speed controller active)
DB31, ...
