C.14 Home Mode12
In Home mode12, the motor will start up at low speed FL, and then accel-
erate to high speed FH towards the limit switch. Once the limit switch is
reached, the motor will go backwards. After changing direction, the
motor will accelerate to FH and search for the index signal. When meet-
ing the raising edge of the index, the motor will slow down, return and
approach the trigger edge again at speed FL. Meanwhile, you can config-
ure how many index counts will be ignored before stopping 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 turning around. Like case 1 in
figure 4-13.
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.

C.15 Home mode13
In Home mode13, the motor will start up at speed FL, and accelerate to
speed FH towards the limit switch. Once the limit switch is reached, the
motor will decelerate and go backwards at speed FL. Once the motor
leave the triggered area of the limit switch, it will stop immediately.
