C.4 Home Mode2
In Home mode2, 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 decelerate, and search for an encoder index signal
with FL. Meanwhile, you can configure how many index counts will be
ignored with “EIC”. When EIC is ‘1’, this means one index will be
ignored and the motor will stop at the second index after the home sensor
is triggered. Like case 1 in the following diagram.
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.
