SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
$MA_SAFE_DES_CHECKSUM[0,1,2]
Reference checksum
Min. input limit: –
Protection level: 7/1
This machine data contains the reference checksum over the actual values of safety–re-
lated machine data that was saved during the last machine acceptance test.
Assigning the indices:
Index 0: Axial monitoring functions and global NC machine data for Safety Integrated
Index 1: HW component IDs
Index 2: PROFIsafe parameters from the S7 configuring
$MA_FIXED_STOP_MODE
Travel to fixed stop mode
Min. input limit: 0
Protection level: 7/2
This machine data defines how the "Travel to fixed stop" function can be started.
0: Travel to fixed stop not available.
1: Travel to fixed stop can be started from the NC program with command FXS[0,1] =1.
2: The function is only controlled from the PLC
3: NCK and PLC are peers [same priority] (user ensures synchronization)
$MA_SAFE_CAM_TRACK_OUTPUT[0...3]
Output assignment cam tracks 1 to 4
Min. input limit: –
Protection level: 7/2
This machine data specifies the outputs for cam tracks 1 to 4.
Configuration: see $MA_SAFE_SVSS_STATUS_OUTPUT
n = 0, 1, 2, 3 corresponds to the assignment for cam tracks 1 to 4
Signal means
= 0, axis is not located on a cam of cam track n
= 1, axis is located on a cam of cam track n
The "safe cam track" function is enabled using MD 36903 $MA_SAFE_CAM_ENABLE.
If MD bit 31 is set, then the signal is processed inverted.
