Data type:
-
Becomes effective:
POWER ON
Number of pulses per encoder revolution (only applies to rotary encoders)
1320 $MD_SAFE_ENC_GEAR_PITCH 611 digital
Lead screw pitch Relevant for:
FD/MSD
Unit:
mm/rev
Default:
10
Minimum value:
0.1
Maximum value:
8 388.00
Data type:
float
Becomes effective:
POWER ON
Gear ratio between encoder and load (applies to linear axes with rotary
encoder)
1321 $MD_SAFE_ENC_GEAR_DENOM[n] 611 digital
Denominator of encoder/load gear Relevant for:
FD/MSD
Unit:
-
Default:
1
Minimum value:
1
Maximum value:
8 388 607
Data type:
long integer
Becomes effective:
POWER ON
Denominator of the gear between encoder and load, i.e. the denominator of the
fraction number of encoder revolutions / number of load revolutions
There are a total of 8 values (n = 0 ... 7); the current value is selected by means
of SGEs.
1322 $MD_SAFE_ENC_GEAR_NUMERA[n] 611 digital
Numerator of encoder/load gear Relevant for:
FD/MSD
Unit:
-
Default:
1
Minimum value:
1
Maximum value:
8 388 607
Data type:
long integer
Becomes effective:
POWER ON
Numerator of the gear between encoder and load, i.e. the numerator of the
fraction number of encoder revolutions / number of load revolutions"
There are a total of 8 values (n = 0 ... 7); the current value is selected by means
of SGEs.
1326 $MD_SAFE_ENC_FREQ_LIMIT 611 digital
Encoder limit frequency for safe operation Relevant for:
FD/MSD
Unit:
-
Default:
300000
Minimum value:
300000
Maximum value:
420000
Data type:
long integer
Becomes effective:
POWER ON
Encoder limit frequency setting due to hardware requirements (encoder cable
length, encoder type). Only applies with 611 digital Performance 2 control
1330 $MD_SAFE_STANDSTILL_TOL 611 digital
Standstill tolerance (SBH) Relevant for:
FD/MSD
Unit: µm or
mdegrees
Default:
1 000
Minimum value:
1
Maximum value:
100 000
Data type:
long integer
Becomes effective:
POWER ON
Tolerance value for the safe standstill monitoring.
This machine data defines the standstill tolerance window for SBH. The actual
value must be within this tolerance value otherwise an alarm is output
