converter only accepts position setpoints that lie within the software limit switches.

In addition, using its digital inputs, the converter evaluates signals from stop cams. When
passing a STOP cam, the converter responds depending on the setting either with a fault or
an alarm.
Fault when passing over a STOP cam
When passing the STOP cam, the converter brakes the axis with the OFF3 ramp-down time,
switches the motor o󹪜 and outputs fault F07491 or F07492.
To switch the motor on again, you must do the following:
1. Switch the motor o󹪜 (OFF1).
2. Acknowledge the fault.
3. Traverse the axis away from the STOP cam, e.g. using the jogging function.
Alarm when passing over a STOP cam
The following happens when the STOP cam is passed:
1. The converter brakes the axis with maximum deceleration.

2. The converter maintains the axis in closed-loop control and reports alarm A07491 or A07492.
In order to bring the axis back into the valid traversing range, you must move the axis away from
the STOP cam, e.g. using the jogging function.
