SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
$MA_SAFE_INFO_ENC_RESOL
Safe encoder resolution
Min. input limit: –
Protection level: 7/0
Display data: Resolution of the encoder being used in the particular gear stage for the
Safety Integrated monitoring functions. With this accuracy, for a single–encoder system,
safety–related positions can be monitored. If different encoders are used for the Safety
Integrated monitoring functions in the drive and in the NCK, then this MD is 0.
$MA_SAFE_ENC_POLARITY
Direction reversal actual value
Min. input limit: –1
Protection level: 7/2
Using this data, the direction of the actual value can be reversed.
= –1: Direction reversal
= 0 or = 1: no direction reversal
$MA_SAFE_ENC_MOD_TYPE
Encoder evaluation type
Min. input limit: –
Protection level: 7/0
Type of the encoder evaluation of this axis used for Safety Integrated. When booting, the
encoder evaluation reads out this type and compares with the value that was last saved
here. This MD is then overwritten. The value of this MD is incorporated in the calculation of
MD $MA_SAFE_ACT_CHECKSUM[1].
$MA_SAFE_ENC_IDENT[n]
Encoder identification
Min. input limit: –
Protection level: 7/0
Identification of the encoder evaluation of this axis used for Safety Integrated. When boot-
ing, the encoder evaluation reads out this identification and compares with the last value
saved here. This MD is then overwritten. The value of this MD is incorporated in the cal-
culation of MD $MA_SAFE_ACT_CHECKSUM[1].
