F253 Incr. encoder emulator: pulse frequency too high
Cause:
The incremental encoder emulator can process a maximum of 1023
increments per sample period (250 µs ); this value has been exceeded.
Remedial action:
1. Reduce the number of lines of the incremental encoder emulator
(P-0-0502).
or
2. Reduce the travel velocity .
See function description: "Incremental Encoder Emulation"
F254 Incr. encoder emulator: hardware fault
Before the next increment output is started, the system checks at the end
of each scan interval (250 µs) whether all increments have been output.
this error is generated if the outputs overlap.
Cause:
•
Internal run time exceeded
•
Hardware error
Recovery:
Switch all functions off (e.g., analog outputs, etc.) that are not needed. If
this does not clear the error, note the number of lines (use P-0-0502) and
traversing speed at which error occurred and call Indramat customer
service.

Emulation"
F255 External power supply DAE 02 error
The analog interface DAE 02.1 requires an external 24-V power supply
that must be connected to terminal X75, pin 8 (+24 V) and pin 9 (0 V).
This error message is issued if the external power supply is missing or
outside the range 18...32 V. This function also detects transient faults,
caused by spikes, etc.
Remedial action:
1. Provide power to the interface from a regulated power supply unit.
2. Use different power supply units or motor brake and interface; in
particular if long motor cables are used.
F267 Erroneous internal hardware synchronization
Cause:
The drive control is synchronized on the bus interface (SERCOS,
Profibus, Interbus, ...). The correct function of the synchronization is
monitored. If the average value of the deviation exceeds 5 µs, this error is
generated.
