Cause and solution
Number | Cause | Solution |
---|---|---|
1 | Too much power required | Reduce the dynamics of the movers in order to reduce the power consumption |
Insufficient cooling of the system | Use external cooling | |
Ambient temperature too high in combination with the two previous points | See preceding points | |
2 | Power supply unit incorrectly adjusted | Adjust the power supply unit settings |
3 | Too little power in the power supply unit, voltage drop | Use a power supply unit with a higher power rating |
Cables too long | Check and adjust cable lengths | |
Circuit breaker tripped | Check circuit breaker | |
4 | Contactor has not switched | Check contactor |
5 | Feedback energy too high | Use brake chopper terminal |
Use more braking resistors | ||
Reduce the dynamics of the movers in order to reduce the power consumption | ||
6 | Excessive load on individual coils of the motor module | Reduce clock rate |
Excessive acceleration of the movers without corresponding pause times | Reduce the mover dynamics | |
7 | XTS task overflow | Add further XTS task, distribute movers and motor modules to both tasks |
Incorrect Distributed Clock settings | Adjust the Distributed Clocks settings | |
No optimum real-time settings | Distribute processor cores and adjust task priorities | |
EtherCAT frame disturbed by external influences | Check EtherCAT cable for damage and connect shield properly | |
Check ESD effects | ||
8 | 48 V supply voltage confused with 24 V control voltage | Check wiring |
9 | Emergency ramp too steep | Adjust the emergency ramp |
Reduce the dynamics of the movers in order to reduce the power consumption | ||
10 | Discharge brushes on the movers defective or missing | Replace the discharge brushes |
11 | Short-circuit in coil "x" of the motor module | Contact Beckhoff Support |
12 | Excessively heavy braking on coil "x" of the motor module | Adjust the braking ramp |
Reduce the load weight on the movers | ||
13 | Movers on the infeed line require too much power | Reduce mover dynamics |
Move movers with a time offset | ||
Add additional infeed module | ||
14 | Movement of too many movers at the same time with high dynamics | Move movers with a time offset |
Reduce mover dynamics |
