C.13 Home Mode11
In Home mode11, the motor will start up at low speed FL, and then accel-
erate to high speed FH towards the home sensor. Once the home sensor is
reached, the motor will decelerate, and go backward while the velocity
goes down to FL. After changing direction, the motor will accelerate to
FH and search for the index signal. When meeting the raising edge of
index, the motor will slow down, return and approach the trigger edge
again with speed FL. Meanwhile, you can configure how many index
counts will be ignore before stopping with parameter “EIC”. When EIC is
‘1’, it means one index will be ignore and the motor will stop at the sec-
ond index after turning around. Like case 1 in figure 4-12.
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. Like case 3 and case 4 in figure 4-6.
