SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 03.2006 Edition
$MA_SAFE_ENC_PULSE_SHIFT
Shift factor of the encoder multiplication
Min. input limit: 2
Protection level: 7/2
Shift factor of the multiplication (resolution) of the encoder, that is used for the Safety
Integrated monitoring functions in the NCK. The encoder value must be divided by 2 by this
factor in order to obtain the number of encoder pulses. A shift factor of 11 corresponds to
an encoder multiplication by a factor of 2048. If the drive provides this information, then this
MD is automatically internally assigned a value after the drive has booted. If the value
changes then Alarm 27036 is output.
$MA_SAFE_ENC_GEAR_PITCH
Lead screw pitch
Min. input limit: 0.1
Protection level: 7/2
Gear ratio of the gearbox (gear) between the encoder and load for a linear axis with rotary
encoder.
$MA_SAFE_ENC_GEAR_DENOM[n]: 0 ... 7
Denominator , gearbox ratio encoder/load
Min. input limit: 1
Protection level: 7/2
Denominator of the gear between encoder and load, i.e. the denominator of the fraction
number of encoder revolutions / number of load revolutions
n= 0, 1, ... ,7 stands for gearbox stages 1, 2, ... 8
The actual value is selected using safety-related input signals (SGE).
MD 36922: $MA_SAFE_ENC_GEAR_NUMERA[n]
$MA_SAFE_ENC_GEAR_NUMERA[n]: 0 ... 7
Numerator, gearbox ratio encoder/load
Min. input limit: 1
Protection level: 7/2
Numerator of the gear between encoder and load, i.e. the numerator of the fraction number
of encoder revolutions / number of load revolutions"
n= 0, 1, ... 7 stands for gearbox stages 1, 2, ... 8
The actual value is selected using safety-related input signals (SGE).
MD 36921: $MA_SAFE_ENC_GEAR_DENOM[n]
