Fig. 6-17 SGA "cam track" and "cam range"
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. 6-17:
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
S SN6
$MA_SAFE_CAM_POS_PLUS[5] = 200
$MA_SAFE_CAM_POS_MINUS[5] = 170
S SN8
$MA_SAFE_CAM_POS_PLUS[7] = 380
$MA_SAFE_CAM_POS_MINUS[7] = 350
Parameterizing the cam range assignment:
(all cams that have been enabled are assigned to cam track 2)
