Diagnostics (and Fault Removal) | 7
7. Central diagnostics via PROFIBUS-DP
An interruption of the connection between podis MOT and MOVIMOT leads to a switch-off of
the connected drive after one second.
The error 921/0x5B is generated by the podis MOT and entered in status word 1, so that it
can be analyzed by the PLC program.
NOTICE
Since this system error generally refers to wiring faults of the MOVIMOT inverter, it is
not possible to reset the control word.As soon as the communication connection is
reestablished, the fault will reset itself.
An interruption of the fieldbus master and podis MOT slave connection after the specified field-
bus timeout time causes process output data to the MOVIMOT to be set to "0".
In addition, input byte bit 7 is deleted and indicates that the MOVIMOT is not operational.
Process input Hex value Meaning
PI1: Status word 1 0X5B20
Error code 91 (5Bhex), bit 5 (fault) = "1",all other
status information is invalid.
PI2: Actual current
value
0Xxxxx Invalid information.
PI3: Status word 2 0X0020
Bit 5 (fault) = "1",all other status information is
invalid.
Input byte of digi-
tal inputs
0X0xBit 5 to bit 7
= "0"
The input information of the digital inputs continue
to be updated.
If not mains voltage is present, error code 93/0x5D is entered in the status word. However, the
error bit is not set to "1".
As soon as the supply voltage returns to the valid range, the error in the status word is
deleted.
In addition, input byte bit 7 is deleted and indicates that the MOVIMOT is not operational.
Process input Hex value Meaning
PI1: Status word 1 0X5D00
Error code 93 (5Dhex), bit 5 (fault) = "0",all other
status information is invalid.
PI2: Actual current
value
0Xxxxx Invalid information.
PI3: Status word 2 0X0020 All other status information is invalid.
Input byte of digi-
tal inputs
0X0xBit 5 to bit 7
= "0"
The input information of the digital inputs continue
to be updated.
