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
6	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
	EtherCAT frame disturbed by external influences	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
9	Emergency ramp too steep	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
12	Excessively heavy braking on coil "x" of the motor module	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
14		Reduce mover dynamics
