4.1.2 Description of the machine data
General General information about machine data and an explanation of their contents
such as unit, data type, protection level, effectiveness, etc. can be found in the
following references:
References:
10089 $MN_SAFE_PULSE_DIS_TIME_BUSFAIL
MD number Delay time until the pulses are cancelled when the drive bus fails
Default: 0
Change becomes effective after POWER ON:
Data type: DOUBLE
Meaning This is the time after the drive bus fails that the pulses are safely cancelled. During this
time, it is still possible to implement a response to the bus failure that is executed
autonomously in the drive (refer to extended shutdown and retraction)
In the following cases, the pulses are immediately cancelled (the system does not wait for
this delay time to expire):
•
•
•
Special cases, errors .$MN_SAFE_PULSE_DIS_TIME_BUSFAIL is transferred using the copy function of the
SI-MD into drive MD 1380 and then subject to a crosswise data comparison.
These general machine data are included in the axial checksum calculation of the safety-
relevant machine data ( $MA_SAFE_ACT_CHECKSUM,
$MA_SAFE_DES_CHECKSUM).
