Function

After start-up, the AX8000 axis module reports the current position to the higher-level controller. An encoder overflow which occures while using the axis, can be handled by the NC. If the system is restarted, however, an unintentional position jump can then occur, since the position is reconstructed from the encoder position.

The modulo function handles this by cyclically storing values in the servo drive. This enables the drive to restore the axis position including the overflow of the encoder. The function can also be applied to prime ratios.

Information on the Modulo function If the ratio corresponds to a value of 2n, the Modulo function is not required. In this case the maximum encoder value is an integer multiple of the maximum application value. This means that no position offset occurs during startup.
