3.2.1 Encoder configuration
E
NCODER RESOLUTION
, A
DDRESS
17.
Number of pulses for one revolution, between 1 and 2048 pulses per revolution.
For 1025 to 2048 pulses per revolution, it is an extrapolated resolution.
E
NCODER MARKER PULSE WIDTH
, A
DDRESS
18.
Width of the encoder marker pulse :
0 : ¼ period of encoder output channel A, gated B\.
1 : ½ period of encoder output channel A, gated B\.
2 : 1 period of encoder output channel A, gated B\.
Firmware version 2005 or higher :
4 : ¼ period of encoder output channel A, gated A\.
5 : ½ period of encoder output channel A, gated A\.
6 : 1 period of encoder output channel A, gated A\.
E
NCODER MARKER PULSE POSITION
, A
DDRESS
19.
Defines the shift between the marker pulse position and the position zero, between
-½ and +½ turn. To shift of 1/x turn enter value 2
16
* 1/x.
E
NCODER DEAD WINDOW
, A
DDRESS
34.
Firmware version 2005 or higher :
Width of the dead window for encoder simulation.
0 :
No dead window
1..xx : Dead window width in REV/4096.
Example :
The motor position oscillates from ±1/4096 revolution.
Without dead window : the encoder outputs change continually (±1 inc.).
With a dead window programmed to 3, the encoder simulation signals will be steady.
This function is useful to reduce vibrations and noises in a system, but be careful that the
position precision is also reduced. The position error is not cumulative.
