$MA_SAFE_ENC_POLARITY
Using this data, the direction of the actual value can be reversed.
= -1: Direction reversal
= 0: no direction reversal or
= 1: no direction reversal
$MA_SAFE_ENC_IS_GEAR_REVERSAL[0..7]
Gearbox direction of rotation reversal
Min. input limit: -
Sets the direction of rotation reversal for the gearbox.
0 (FALSE): no direction of rotation reversal
1 (TRUE): direction of rotation reversal
n = 0, 1, ... 7 stand for gearbox stages 1, 2, ... 8
The actual value is selected using safety-related input signals (SGE).
$MA_SAFE_ENC_MOD_TYPE
Encoder evaluation type
Min. input limit: 0
Type of the encoder evaluation of this axis used for Safety Integrated.
= 1: Sensor Module (SMI, SMC, SME)
= 2: DRIVE-CLiQ encoder
= 3: EnDatV2.2 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
