SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
$MA_SAFE_INFO_ENC_RESOL
safety-relevant encoder resolution
Min. input limit: –
Protection level: 7/–
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-relevant 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 of rotation reversal
= 0 or = 1: no direction reversal
$MA_SAFE_ENC_MOD_TYPE
Encoder evaluation type
Min. input limit: –
Protection level: 7/–
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.
$MA_SAFE_ENC_IDENT[n]
Encoder identification
Min. input limit: –
Protection level: 7/–
Identification of the encoder of this axis used for Safety Integrated. When booting, the
encoder evaluation reads-out this identification and compares with the last value saved
here. This MD is then overwritten.
