Meaning
Internal module error occurred
•
Possible cause: Technology module
•
defective
No technology module L+ supply voltage
Technology module cannot send an
•
interrupt because a previous interrupt has
not been processed
Possible causes:
•
– Parameter assignment error
– Too many hardware interrupts in too
short a time
No normal operation of the technology
•
module possible
Possible cause: Technology module is
•
performing a firmware update
Technology module defective
H
Firmware error
H
Technology module defective
Error at encoder supply
•
H
Possible causes:
•
– Short circuit
– Overload
Error at the digital outputs
•
H
Possible causes:
•
– Short circuit
– Overload
Error at supply voltage L+
•
H
Possible causes:
•
– Low voltage
– Wiring of L+ supply voltage defective
Time profile of signals A and B of the
•
H
incremental encoder does not meet
certain specifications
Possible causes:
•
– Signal frequency too high
– Encoder faulty
– Process wiring faulty
To correct or avoid errors
Replace technology module
Check BaseUnit type
•
Check the wiring of the supply voltage
•
L+ on the BaseUnit
Change interrupt processing in the CPU
and re-assign technology module
parameters correspondingly
Wait until technology module is available
again
Replace technology module
Run firmware update
Replace technology module
Check encoder wiring
•
Check consumers connected to encoder
•
supply
Check wiring at the digital outputs
•
Check consumers connected to the
•
digital outputs
Check the L+ supply voltage
•
Check the wiring of the supply voltage
•
L+ on the BaseUnit
Check process wiring
•
Check encoder/sensor
•
Check parameter assignment
