Suppose that the resolution of the conveyor encoder is similar to the resolution of the

x-axis encoder. To draw an exact circle on the moving cake, the motion 10,000 * cos(2πt) is

programmed as PVT and RM=1, FR[3]=1.

11.2.2 ECAM

ECAM is an acronym for electronic CAM, in which the position reference to the drive is

not directly proportional to the total external inputs, but is rather a function of them.

The ECAM-related commands are as follows:

Commands Action

EM[1] Indicates whether the ECAM function is active:

2: ECAM is cyclical.

1: ECAM is linear.

0: Direct external referencing.

Set EM[1] to synchronously activate the most recent settings of EM[2],

EM[3], EM[4], EM[5] and EM[7].

EM[2] Last valid index of ECAM table. Maximum for EM[2] is 1024.

The EM[2] setting goes into effect only at next setting of EM[1] or next

MO=1.

EM[3] Starting position: value of the input to the ECAM function for which

the output of the ECAM function will be ET[EM[5]] (ET of EM[5]).

If EM[3] is out of range for PY, it will be taken modulo PY.

EM[4] Table difference (see sections

11.2.2.1 and 11.2.2.2).

The EM[2] setting goes into effect at next setting of EM[4] or next

MO=1.
