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
