Operational and error diagnosis

14 Operational and error diagnosis
Operation of the frequency inverter and the connected load are monitored continuously. Various func-
tions document the operational behavior and facilitate the operational and error diagnosis.
14.1

Status of digital signals

The status display of the digital input and output signals enables checking of the vari-ous control sig-
nals and their assignment to the corresponding software functions, in particular during commissioning.
Parameters
Status digital inputs
be converted to binary values in order to obtain the status information.
Assignment:
Control sig. 8
Control sig. 7
Control sig. 6
Control sig. 5
Control sig. 4
Control sig. 3
Control sig. 2
Control sig. 1
A decimal value is displayed, indicating the status of the digital signals in bits after conversion into a
binary figure.
Example:
Decimal figure 33 is displayed. Converted into the binary system, the number reads 00100001. Thus,
the following contact inputs or outputs are active:
Digital input or output 1
Digital input or output 6
14.2

Controller status

The controller status can be used to establish which of the control functions are active. If a several
controllers are active at the time, a controller code com-posed of the sum total of the individual codes
is displayed. Display of the controller status via the operator panel can be parameterized via parame-
ter
