36933 $MA_SAFE_DES_VELO_LIMIT
MD number Evaluation factor to limit the speed setpoint
Default: 0
Change effective after RESET
Data type: DWORD
Meaning Evaluation factor to define the setpoint limit from the actual speed limit. The active SG
limit value is evaluated with this factor and specified to the interpolator as the setpoint
limit. Setpoint 0 is specified when SBH is selected.
If 100% is entered, the setpoint is limited to the active SG stage.
If 0% is entered, the speed setpoint limit is not active.
Corresponds with ...
Special cases, errors This MD may have to be altered several times before an optimum setting for the dynamic
response of the drives is found. To prevent this procedure from being unnecessarily
awkward, "reset" has been defined as the activation criterion.
This data is not included in the crosswise data comparison with the drive.
This data is not included in the axial checksum $MA_SAFE_ACT_CHECKSUM, as it is a
single-channel function.

36934 $MA_SAFE_POS_LIMIT_PLUS[n]
MD number Upper limit value for safe end position
Default: 100 000 mm
Change becomes effective after POWER ON:
Data type: DOUBLE
Meaning The upper limit value for safe end positions 1 and 2 is specified here.
If SE1 or SE2 is selected and the actual position exceeds the limit set in this data, the
control system activates Alarm 27012 with the stop response configured in
$MA_SAFE_POS_STOP_MODE and changes over to the SBH mode. A violation of the
SBH tolerance window initiates stop response STOP B and A.
n = 0, 1 stands for upper limit value of SE1, SE2
Corresponds with ... MD 36962: $MA_SAFE_POS_STOP_MODE
MD 36935: $MA_SAFE_POS_LIMIT_MINUS[n]
MD 36901: $MA_SAFE_FUNCTION_ENABLE
Special cases, errors If a lower or identical value is entered in MD: $MD_SAFE_POS_LIMIT_PLUS[n] than in
MD: $MA_SAFE_POS_LIMIT_MINUS[n], then a parameterizing error is displayed.
36935 $MA_SAFE_POS_LIMIT_MINUS[n]
MD number Lower limit value for safe end position
Default: -100 000 mm
Change becomes effective after POWER ON:
Data type: DOUBLE
Meaning The lower limit value for safe end positions 1 and 2 is specified here.
If SE1 or SE2 is selected and the actual position drops below the limit set in this data, the
control system activates Alarm 27012 with the stop response configured in
$MA_SAFE_POS_STOP_MODE and changes over to the SBH mode. A violation of the
SBH tolerance window initiates stop response STOP B and A.
n = 0, 1 stands for lower limit value of SE1, SE2
Corresponds with ... MD 36962: $MA_SAFE_POS_STOP_MODE
MD 36934: $MA_SAFE_POS_LIMIT_PLUS[n]
MD 36901: $MA_SAFE_FUNCTION_ENABLE
Special cases, errors If a lower or identical value is entered in MD: $MD_SAFE_POS_LIMIT_PLUS[n] than in
MD: $MA_SAFE_POS_LIMIT_MINUS[n], then a parameterizing error is displayed.
