Which products are affected?
EVF93XX-EV.XX.21
Drive control via field bus (Profibus, Interbus)
What happens?
If the controller is enabled the drive indicates under C0183 (drive status) 'DC brk AIF' or 'DC brk C135'. However, a DC injection braking is not executed.
When does the problem occur?
AIF-CTRL.B4 or control word C135.B4 is permanently connected to the DC injection braking function although the bit can freely be assigned according the documentation (Manual, GDC).
Note:
If the communication modules and the DRIVECOM profile are used, it must be observed that the bit 5 control word is shown inversely on the AIF-CRTL.B4 bit.
Possible diagnostics?
The AIF-IN-CTRL.B4 output is used in the drive control.
Short-term measures/recommendations?
Use another free control bit instead of AIF-IN-CTRL.B4.
Evaluation:
The error immediately occurs during commissioning.
