The master encoder may be a "virtual master", a higher-level PLC, or an encoder system. The channels for the encoder system to be used are selected from the list box. Channel 3 is only available if an external interface X8 (option module) is present. If a higher-level PLC is used as the master encoder P 1319 MPRO_ECAM_CamMaster_Axis_Type = PARA(2), the resolution must be set referred to one motor revolution
P 0250 MPRO_ECAM_PARAMaster_Amplitude.

Function |
|---|---|---|
| P1320 | MPRO_ECAM_CamMaster_RevLockMode | Anti-reverse mode |
| (0) | INACTIVE | Anti-reverse mode inactive |
| (1) | ACTIVE with waycompensation | Anti-reverse mode with path compensation: While the slave accelerates to the speed of the master during engagement, the master and slave do not move synchronously. To catch up the advancing master, select the "path-compensated" function. |
| (2) | ACTIVE without waycompensation |
Anti-reverse mode without path compensation |

Filter type for guide value
When using a real master encoder, encoder signals may be subject to noise. The signals can be filtered with a PT1 element or a mean value filter
.
