Data bits (Data)
The data bus width is 12 bits. The first 9 bits are used to transfer the data
for the different operating parameters to the control unit. The data for the
corresponding preset values are assigned with an identification number,
consisting of 3 bits.
Control bits (Control)
For inputs, there are 3 control bits available:
- Axis Start - Start/Stop axis
- Strobe - Data transfer activation
- Remote - Operating mode
Status bits (Status)
For outputs, there are 2 status bits available:
- Error - Axis not referenced
- Program active
Status bit 1:
Status bit 1 has assigned two functions:
1. After switching on, an impulse of 0.1 s is present, that means, the
axis has to be referenced:
OptiMove ON
2. The composite error message indicates all errors which are
present in the control unit. Error function according to system
parameter P8:
P8=0 - Error
P8=2 - Error
Status bit 2:
Status bit 2 indicates the operating status of the axis. The following
diagram shows how the output reacts in the different operating modes:
