9.2 E-CAM Application
In electrical cam system of DVP-PM, we have to set up the master shaft (Master) which simulates mechanical
cam, and also the slave shaft (Slave) which simulates the cam follower. In this section we will introduce the
methods to obtain Master position and relationship between Master and Slave (E-CAM data).

9.2.1 Initial Settings
9.2.1.1 Set E-CAM Data

There are 2 methods applicable for setting up E-CAM data in DVP-PM:
Method 1: Use DTO instruction to create E-CAM data directly.
Method 2: Use E-CAM Chart of PMSoft to draw the CAM curve
For detailed explanation on the setting methods of E-CAM data, please refer to section 9.4
9.2.1.2 Set Terminal Polarity
 Input Terminals
1. MPGA0/MPGB0: Pulse input terminal for Master. Max allowable frequency: 200kHz.
