$MA_SAFE_ENC_IS_LINEAR
This MD specifies whether a linear or a rotary encoder is connected.
= 0:
rotary encoder is connected, its resolution is specified using MD36918 $MA_SAFE_ENC_RE‐
SOL - and converted over to the load side using MD36920 $MA_SAFE_ENC_GEAR_PITCH,
MD36921 $MA_SAFE_ENC_GEAR_DENOM[n] and MD36922 $MA_SAFE_ENC_GEAR_NU‐
MERA[n].
MD36917 $MA_SAFE_ENC_GRID_POINT_DIST is of no significance.
= 1:
linear encoder is connected, MD36917 $MA_SAFE_ENC_GRID_POINT_DIST is used to
specify its resolution.
MD36918 $MA_SAFE_ENC_RESOL, MD36920 $MA_SAFE_ENC_GEAR_PITCH, MD36921
$MA_SAFE_ENC_GEAR_DENOM[n] and MD36922 $MA_SAFE_ENC_GEAR_NUMERA[n]
are of no significance.
If the value changes then Alarm 27036 is output.
For 0:
MD36918 $MA_SAFE_ENC_RESOL
MD36920 $MA_SAFE_ENC_GEAR_PITCH
MD36921 $MA_SAFE_ENC_GEAR_DENOM[n]
MD36922 $MA_SAFE_ENC_GEAR_NUMERA[n]
For 1:
MD36917 $MA_SAFE_ENC_GRID_POINT_DIST
$MA_SAFE_ENC_GRID_POINT_DIST
Grid spacing, linear scale
Min. input limit: 0.000 01
This MD specifies the grid spacing of the linear scale used here.
Not relevant for rotary encoders.
If the value changes then Alarm 27036 is output.
$MA_SAFE_ENC_RESOL
Encoder pulses per revolution
Min. input limit: 1
This MD specifies the number of pulses per revolution for a rotary encoder.
Not relevant for a linear encoder.
If the value changes then Alarm 27036 is output.
Protection level: 7/2
Protection level: 7/2
