Normal Type E-CAM

When the E-CAM type is Normal, the slave axis command position is calculated as follows:

  • If the master axis is exactly at one of the positions in the E-CAM table, the slave axis is commanded the corresponding position.

  • If the master axis is between two positions in the E-CAM table, the slave axis is commanded a position calculated by linearly interpolating between the two corresponding positions.

  • If the master axis is outside the range of positions in the E-CAM table, the slave axis is commanded the corresponding position of the closest position in the E-CAM table.

The following example illustrates a typical Normal type E-CAM table:

Master Axis Position

Slave Axis Position

-10000

1000

-5000

1500

0

1000

5000

500

10000

1000

The above E-CAM table will command the slave axis based on the master axis position as shown in the following plot:
