Which products are affected?
9300EP position controller V7.0
9300ES servo controller V7.0
Eliminated function restriction
The output signal was not generated correctly if the master frequency signal at the DFRFG1-IN input was negative and the DFRFG1-QSP input was reset.
Now, the negative master frequency signals are processed correctly.
Which products are affected?
9300EP position controller <= V6.2
9300ES servo controller <= V6.2
What happens?
The output signal is not indicated correctly if the master frequency signal at the DFRFG1-IN input is negative and the DFRFG1-QSP input has been reset.
When does the problem occur?
The problem occurs if the master frequency signal at the DFRFG1-IN input is negative and the DFRFG1-QSP input has been reset.
Possible diagnostics?
Make an oscilloscope trace of the DFRFG1-OUT output signal. If necessary use a converter instead of the internal oscilloscope in order to adjust the signal from phase difference to analog.
Short-term measures/recommendations?
None.
Evaluation:
In most cases the applications can be converted to positive signals.
