Functions of the digital inputs
The control word is the central control object in the X6 unit series.
Alternatively or in combination, operation via digital inputs is also possible.
Parameters di10 to di21 are available to this.
If the parameters co28 / co29 are not used to link the controlword and digital input
setting, the processing sequence is as follows:
• Processing of the process data
• Evaluation of the digital inputs
• Access via asynchronous communication (e.g. diagnostic interface or
SDOs)
• Processing of the combination logic (7.1.9.1.2 Combined setting via con-
trolword and digital inputs
If several inputs are selected for a function, these are OR operated.
With active RUN input, value 0x000b is written into the internal
control word (=> leads only to status operation enabled at co32
Bit 3 = 0)
The selected input influences bit 7: "fault reset" of the control-
word internal co31
The input selected as CA input influences the bits of the control-
word internal selected by CA mask.
The input selected as CB input influences the bits of the control-
word internal selected by CB mask.
Rotation setting via digital inputs
If defined and input active, the setpoint speed from the vl param-
eters is set to zero
The selected input influences bit 4:“op mode spec“ of the con-
trolword internal co31
If set, the speed setpoint is inverted in operating modes 1 and 2.
Actual index. Results from the state of the inputs, which are se-
lected with di21 index input for the index setting.
Common filter for all inputs which form together the index
The selected input influences bit 8: halt in the internal control-
word.
Selection of the input which shall be used as strobe signal for in-
dex generation.
