8 Electronic Cam 8.8 Modifying Key Points for Electronic Cams
◆
Example:
When M10 is set to ON, the PLC executes DCAMRD instructions to read the cam table. The read data is
stored in D elements starting with D200.
Master and slave axes of each key point occupy two 32-bit registers; that is, each key point occupies four D
elements. If ve points are read, from the rst point, (D201, D200) indicates the master axis position, (D203,
D202) indicates the slave axis position, and so on. Twenty D elements are occupied.

Functions and actions
The CAMRD instruction reads electronic cam table data in the unit of pulses.
●
[m1] species a cam table to be read. When m1 = k11 to k13, the
M-Pos value (SD48, SD49) of an X axis
cam, the M-Pos value (SD148, SD149) of a Y axis cam, and the M-Pos value (SD248, SD249) of a Z axis cam are
specied, respectively
.
●
[m2] sets the starting point, m2 = k1 to k360.
●
[D] indicates the starting address. Multiple continuous address units starting with [D] are occupied.
Each key point occupies two 32-bit registers that ag positions of master and slave axes respectively;
that is, each key point occupies four address units.
