C.7 Home Mode5

In Home mode5, 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 go backwards while the velocity

reaches FL. After changing direction, the motor will accelerate to FH and

search for the index signal, then slow down and stop. Meanwhile, you can

configure how many index counts will be ignored before stopping with

parameter “EIC”. When EIC is ‘1’, it means one index will be ignored

and the motor will stop at the second index after turning around. Like

case 1 in 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. Like case 3 and case 4 in figure 4-6.
