S If a cam is enabled in $MA_SAFE_CAM_ENABLE, then it must also be
assigned.
If a violation is determined when making these checks, then alarm 27033 "Parame-
terization invalid" / F01686 "SI Motion: Cam position parameterization not permissi-
ble" is output.
The generation of the new cam SGA is shown in Fig. 6-20:

Note
The traversing range for rotary axes must lie within +/--2048 revolutions. This
corresponds to the value range of the safety--related actual value.
Parameterization example for Fig. 6-20:
Enabling the cams SN1, SN2, SN3, SN6, SN8:
$MA_SAFE_CAM_ENABLE = 0xA7 (0000 0000 0000 0000 0000 0000 1010 0111);
Parameterizing the cam positions for the cams that have been enabled:
S SN1
$MA_SAFE_CAM_POS_PLUS[0] = 480
$MA_SAFE_CAM_POS_MINUS[0] = 455
S SN2
$MA_SAFE_CAM_POS_PLUS[1] = 120
$MA_SAFE_CAM_POS_MINUS[1] = 80
S SN3
$MA_SAFE_CAM_POS_PLUS[2] = 320
$MA_SAFE_CAM_POS_MINUS[2] = 300
