Fasten the reference point switch (if required) between the hardware limit
S
switches under the following condition:
There is a point at which both the reference point switch and the hardware
limit switch near the motor respond at the same time (x < d, see Fig. 27).
Checking the correct function:
1. Push the slide into a mechanical end position.
2. If necessary, loosen the coupling briefly.
3. Check whether the safety limit switches and the reference point switch
function correctly and whether the switching cams are seated without play.
Repeat points 1 to 3 in the other end position.
Carr ying out commissioning
1. Start reference travel at a low slide speed from the centre of the stroke (O/2) in
the direction of the reference point switch.
2. Start test travel limited to low dynamics.
3. Check whether the product fulfils the following requirements:
The slide moves through the complete intended positioning cycle.
The slide stops as soon as it reaches a limit switch.
If the sensors do not respond, refer to the chapter Instructions on faults" or to
S
the operating instructions.
Test run without faults:
Repeat the test travel several times with gradual increase in speed until the
S
desired operating speed is reached.
If set correctly, the slide will brake completely when it overruns a hardware
limit switch before the safety limit switch responds.
In the case of deviations from the set behaviour:
Check the following points on your system:
S
the drive package
the mechanical fittings
the electrical connections
(see also the chapter Eliminating faults").
