9.5 Multi-axis E-CAM
Single-axis E-CAM can be executed in cyclic operation and acyclic operation. Unlike single-axis E-CAM,
multi-axis E-CAM can only be executed in cyclic operation. For multi-axis E-CAM, only one set of E-CAM Charts
can be applied, i.e. CAM Chart 0 ~ CAM Chart 2 correspond to X, Y, Z axis.
Same as single-axis cyclic E-CAM, multi-axis E-CAM is enabled by setting b13 of D1846 as ON. In addition to
setting D1846, work modes of each axis should also be set up and enabled, and C200 should be activated for
counting pulses of Master.
1. D1846
Set b13 of D1846 as ON (D1846 =H’2000) to enable multi-axis E-CAM.
