SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) - - 10.2015 Edition
$MA_SAFE_ENC_MOD_TYPE
Encoder evaluation type
Min. input limit: 0
Protection level: 7/- -
Type of the encoder evaluation of this axis used for Safety Integrated.
= 1: Sensor Module (SMI, SMC, SME)
= 2: DRIVE- -CLiQ encoder
= 3 EnDat 2.2 converter
This type is read out of drive parameter r9527 when booting. If a valid value has not been
entered, alarm 27038 is output. If the drive parameter contains a valid value, then this is
compared with the last value saved in this MD. This MD is then overwritten. Alarm 27035 is
output if they are not equal. The value of this MD is incorporated in the calculation of
MD36998 $MA_SAFE_ACT_CHECKSUM[1].
$MA_SAFE_ENC_IDENT[0...2]
Encoder identification
Min. input limit: 0
Protection level: 7/- -
Identification of the encoder evaluation of this axis used for Safety Integrated. When boot-
ing, the encoder evaluation (drive parameter r9881) reads out this identification and com-
pares with the last value saved here. This MD is then overwritten. The value of this MD is
incorporated in the calculation of MD36998 $MA_SAFE_ACT_CHECKSUM[1].
