*1) The parameter numOfUsedCams defines the interrupt cycle time (Therefore, it takes effect to the accuracy of the track) and the behaviour of the module if the DC information is lost.
| Parameter setting for numOfUsedCams | Number of cams used | Interrupt cycle time | Behaviour if DC information is lost |
|---|---|---|---|
| 0 | 0 | 50 µs | Module changes to “safe-operational” state; the outputs are activated trough the user program |
| 1…8 | 1…8 | 80 µs | |
| 9…16 | 9…16 | 100 µs | |
| 17…32 | 17…32 | 200 µs | |
| 128 | 0 | 50 µs | Module keeps in “operational” state; the outputs are activated trough the user program |
| 129…136 | 1…8 | 80 µs | Module keeps in “operational” state; the cam switch outputs are activated according to an interpolated timing information |
| 137…144 | 9…16 | 100 µs | |
| 145…170 | 17…32 | 200 µs |
*2) The parameter resolution defines the angle resolution of the track. The value gives the number of increments related to 360°; e. g. the value 36,000 corresponds to an angle resolution of 0.01°.
*3) The parameter zeroShift defines the zero shift. With it the encoder can be adjusted to the mounting position. The value of zeroShift is set in encoder-increments. It is not assigned to the parameter resolution of the cam switch.
*4) The parameter EncoderBitResolution defines the resolution of the used encoder (in bits), e. g. with the default setting 18 bits the encoder has 196,608 divisions.
