9 Electrical CAMDVP-PM Application Manual9-29.2 E-CAM ApplicationIn electrical cam system of DVP-PM, we have to set up the master shaft (Master) which simulates mechanicalcam, and also the slave shaft (Slave) which simulates the cam follower. In this section we will introduce themethods to obtain Master position and relationship between Master and Slave (E-CAM data).
