Difference in between the encoder marker and 0 position at parameter 3.29. On power up, SLM uses single cycle Sin-Cos output to find
absolute shaft position. This measurement has a maximum of ±3° error. After passing through Marker pulse this offset is calculated.
This is offset in between SLM marker pulse and shaft key, set by motor manufacturer.
User specified marker offset for encoder simulation.
Range selectable from 100 lines per revolution to 8192 lines per revolution
Set this parameter to 0 enables 16384 pulses per revolution
When modified, in order for the new value to take effect, a power-down and up again is required.
0 = Quadrature A & B differential outputs (Including Marker pulses)
1 = Frequency & Directional differential outputs (Including Marker pulses)
Allows the user to select which gain buffer is required. Buffer selection:
x = don't care conditions
Refer to parameters 3.10, 3.11, 3.12
Used to indicate which PID buffer currently in use.
