C.12 Home Mode10
In Home mode10, the motor will start up at low speed FL, and accelerate
to high speed FH towards the home sensor. Once the home sensor is
reached, the motor will start to search the encoder index signal for the
high speed FH. After the index is reached, the motor will decelerate to FL
then go backward with speed FL. At this time, the motor will stop when
the index trigger edge was met. Meanwhile, you can configure how many
index counts will be ignored when passing the home sensor with parame-
ter “EIC”. When EIC is ‘1’, it means one index will be ignored and the
motor will stop at the second index after the home sensor was triggered.
Like case 1 in figure 4-11.
If the home sensor was active at start up, or the limit switch was met first,
the motor will go in the opposite direction when reaching the limit switch.
Then it will keep moving until it crosses the home sensor, and finally
search the home signal again.
