Table 6-45 List of input signals, continued
Signal name, description
Fixed end stop, sensor (from SW 3.3)
Using this input signal, the drive recognizes the "fixed endstop reached" status via an external sensor.
1 signal Fixed endstop is reached
0 signal Fixed endstop has not been reached (standard)
Prerequisites:
The signal is only effective, if P0114 (fixed endstop, configuration 2) = 1.
Note:
The "travel to fixed endstop" function is described in Chapter 6.12.
Request passive referencing
(from SW 5.1)
Using this input signal, passive referencing for the slave drive is controlled.
1/0 signal Set reference point
P0179
= 0: The value in P0160 (reference point coordinate) is set as the actual axis position.
= 2: The axis moves through the deviation to the reference position.
0/1 signal The reference cam and zero mark search are activated
An appropriate fault is signaled if a zero mark has not been found up to the 1/0 edge.
Note:
The "passive referencing" function is described in Chapter 6.3.
Tracking mode
The tracking mode for the axis is selected via this input signal.
1 signal Selecting tracking operation
The axis is switched into the tracking mode if the controller enable is additionally with-
drawn via terminal 65.x.
In the tracking mode, the position control loop is open. The position reference value con-
tinuously tracks the actual value, i.e. the actual value is further sensed and updated but a
setpoint is not output.
If the axis is shifted from its position due to external effects, then the monitoring does not
output an error message.
0 signal Canceling the tracking mode
If the controller is re–enabled, then the axis movement continues at the new actual posi-
tion which could have changed.
The position control loop is closed.
Note:
S
The tracking mode status is displayed via the "tracking mode active" output signal.
S
The tracking mode can also be selected as internal control response to an error.
