Stop cam minus active (r2684.13)
Stop cam plus active (r2684.14)
These status signals indicate that "Stop cam, minus" (p2569) or "Stop cam. plus" (p2570)
has been exceeded or not reached. The signals are reset when the cams are left in the
direction other than that in which they were approached.
Axis moves forwards (r2683.4)
Axis moves backwards (r2683.5)
Axis accelerates (r2684.4)
Drive decelerates (r2684.5)
Drive stationary (zero speed) (r2199.0)
These status signals indicate the current condition of motion. If the actual absolute speed is
less or equal to p2161, then the status signal "drive stationary" is set - otherwise it is deleted.
The signals are appropriately set if jog mode, reference point approach or a traversing task
is active.
Cam switching signal 1 (r2683.8)
Cam switching signal 2 (r2683.9)
The electronic cam function can be implemented using these signals. Cam switch signal 1 is
"0" when the actual position is greater than p2547, otherwise the signal is "1". Cam switch
signal 2 is "0" when the actual position is greater than p2548, otherwise the signal is "1". The
signal is, therefore, canceled when the drive is beyond the cam switch position. The position
controller initiates these signals.
Direct output 1 (r2683.10)
Direct output 2 (r2683.11)
If a digital output is parameterized, the function "direct output 1" or "direct output 2", then it
can be set by a corresponding command in the traversing task (SET_O) or reset
(RESET_O).
Following error in tolerance (r2684.8)
When the axis is traversed in closed-loop position-controlled mode, the permissible following
error is calculated from the current velocity and the selected Kv factor on the basis of a
model. Parameter p2546 defines a dynamic following error window that defines the
permissible deviation from the calculated value. The status signal indicates as to whether the
following error is within the window (status 1).
