Limitation of the digital frequency output before the limit frequency is reached (elimination)

Eliminated from:
EVS93xx-EI (Servo PLC V8.0)
EVS93xx-ET (Servo PLC V8.0 with technology function)

Behaviour of the new version?
The frequency which is output via the digital frequency output is limited to the value set in code C1799.



What happens?
The frequency of the signal which is output via the digital frequency output is limited before the limit frequency set in code C1799 (=DFOUT fmax) is reached.

When does the problem occur?
The limitation described before occurs if code C0540 (=DFOUT_IO fuction) has either been configured with 0 (=DFOUT_nOut_v as %) or 1 (=DFOUT_nOut_v as rpm).

Which products are affected?
EVS93xx-EI (Servo PLC V7.2 and lower)
EVS93xx-ET (Servo PLC V7.2 and lower with technology function)

Possible diagnostics?
None.

Short-term measures/recommendations?
Set the max. limit frequency (1250kHz ) in code C1799.

Evaluation:
If a limit frequency less than 1250kHz is entered the frequency of the signal which is output via the digital frequency output is limited more strongly than specified.
