SINUMERIK 840D sl/SINAMICS S120 SINUMERIK Safety Integrated (FBSI sl) – 05.2008 Edition
$MA_SAFE_ENC_IS_LINEAR
Linear scale
Min. input limit: 0
Protection level: 7/2
This MD specifies whether a linear or a rotary encoder is connected.
= 0:
A rotary encoder is connected, $MA_SAFE_ENC_RESOL is used to specify its resolution
and $MA_SAFE_ENC_GEAR_PITCH, $MA_SAFE_ENC_GEAR_DENOM[n] and
$MA_SAFE_ENC_GEAR_NUMERA[n] are used to convert it to the load side.
The MD: $MA_SAFE_ENC_GRID_POINT_DIST has no significance.
= 1:
Linear encoder is connected, $MA_SAFE_ENC_GRID_POINT_DIST is used to specify its
resolution.
The MDs: $MA_SAFE_ENC_RESOL, $MA_SAFE_ENC_GEAR_PITCH,
$MA_SAFE_ENC_GEAR_DENOM[n] and $MA_SAFE_ENC_GEAR_NUMERA[n] have no
significance.
This MD cannot be written to, the encoder type must be parameterized in the drive.
If the value changes then Alarm 27036 is output.
For 0:
$MA_SAFE_ENC_RESOL
$MA_SAFE_ENC_GEAR_PITCH
$MA_SAFE_ENC_GEAR_DENOM[n]
$MA_SAFE_ENC_GEAR_NUMERA[n]
For 1:
$MA_SAFE_ENC_GRID_POINT_DIST
$MA_SAFE_ENC_GRID_POINT_DIST
Grid spacing, linear scale
Min. input limit: 0.000 01
Protection level: 7/2
This MD specifies the grid spacing of the linear scale used here.
Not relevant for rotary encoders.
$MA_SAFE_ENC_RESOL
Encoder pulses per revolution
Min. input limit: 1
Protection level: 7/2
This MD specifies the number of pulses per revolution for a rotary encoder.
Not relevant for a linear encoder.
Max. input limit: 1
Unit: –
Max. input limit: 8
Unit: mm
Max. input limit: 100 000
