Figure H009 illustrates a homing sequence on the home switch and index pulse with a negative initial move.

Homing Methods 15, 16, 20, 22, 24, 26, 28, and 30: Reserved
Homing methods 15, 16, 20, 22, 24, 26, 28 and 30 are reserved for future use.
2.17.7.7
Homing Methods 17 and 18: Homing without an Index Pulse
These methods are similar to methods 1-2, except that the home position is not dependent on the index pulse but
only on the relevant limit switch translation. Method 17 uses the negative limit switch, and method 18 uses the
positive limit switch.
2.17.7.8
Homing Methods 19, 21, 23, 25, 27, and 29: Homing without an Index Pulse
These methods are similar to methods 1 to 14, except that the home position does not depend on the index pulse.
Instead, it depends on the relevant home or limit switch transitions. For example, method 19 is similar to method 3
as shown in Figure H010.

This means method 19 and 20 (as described in the Profile for Drives and Motion Control) both imply the same
home algorithm and location, because methods 3 and 4 are only different in which index pulse the locate.
Likewise, 22, 24, 26, 28, and 30 (as described in the Profile for Drives and Motion Control) are redundant. For this
reason, in AC Tech amplifiers, the following redundant home methods are reserved: 20, 22, 24, 26, 28, and 30.
The equivalent home method (one less then each of these values) should be used instead.

Homing Methods 31 and 32: Reserved
Homing methods 31 and 32 are reserved for future use.
