Functions and actions
The CAMWR instruction modies electronic cam table data in the unit of pulses.
●
[m1] species a cam table to be modied. 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 of key points, m2 = k2 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.
●
[n] indicates the number of key points. (m2 + n – 1) must be less than or equal to the number of
downloaded key points.

Notes:
1) ECAMWR
instructions are used to modify oating-point decimal data.
2) Except for [D] data interpreted as oating-point decimal data,
ECAMWR
instructions
are used in the same way as CAMWR instructions. For details, see
“CAMWR: Writing
electronic cam data” on page 576
