Cause and solution
12.1.3
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 pre-
vious 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 brake 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 motor voltage and 24 V control voltage mixed up
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 power supply segment require too much power
Reduce mover dynamics
Move movers with a time offset
Add additional power supply module
14
Movement of too many movers at the same time with high dy-
namics
Move movers with a time offset
Reduce mover dynamics
