Which products are affected?
8200vector 0.25 - 90 kW (≤ SW 3.1) with standard I/O or application I/O (≤ SW 3.1)
8200motec 0.25 - 7.5 kW (≤ SW 3.1) with standard I/O or application I/O (≤ SW 3.1)
What happens?
Transferring parameter sets to the device via GDC or keypad is impossible, when the parameter set changeover is configured (e. g. to digital input E1) and active (e. g. digital input E1= HIGH, this results e. g. in parameter set 2 active) at the same time. In this case, the parameter set transfer is aborted and the device indicates a 'CCr' trip or a 'CE5' trip. The communication between GDC or keypad and controller is interrupted.
When does the problem occur?
The problem occurs when the parameter set changeover is active when downloading parameter sets via GDC or keypad.
Possible diagnostics?
When transferring parameter sets when the parameter set changeover is active, a 'CCr' trip or a 'CE5' trip is triggered and the communication to GDC is interrupted.
Short-term measures/recommendations?
When transferring parameter sets via GDC or keypad, the signal levels for the parameter set changeover must not be active (for the example given above: digital input E1 = LOW). If this is not possible, e. g. when configuring the parameter set changeover to internal signals such as Qmin, transfer the parameter sets without the configured parameter set changeover first. Then, set the parameter set changeover manually.
Evaluation
Basic device & standard I/O:
The problem occurs during set-up, when downloading parameter sets. When cancelling the trigger signal, the frequency inverter can be operated again, the error can be reset.
Basic device & application I/O:
The problem occurs during set-up, when downloading parameter sets. When cancelling the trigger signal, the frequency inverter can be operated again, the error can be reset.
In the software of the application I/O, this problem cannot be solved.
