Return velocity sets the speed in user units/second. Refer to Homing

for more information.

Absolute Homing

If you are interfacing with the IMC-S/23x through an absolute
transducer and are using a single resolver, parallel encoder or a
magnetorestrictive transducer as an absolute feedback device:

1. Select ABSOLUTE as the homing procedure. The following

message appears:

2. Toggle through the list to select the absolute transducer and press

ENTER.

Note:

Use the absolute homing procedure only on axes
configured for absolute feedback.

You can use the REC-4096 with Allen-Bradley dual resolver packages
under an ABSOLUTE homing procedure. You need to home each of
the two resolvers in the package separately using two axis inputs from
the IMC-S/23x. The application program must calculate the absolute
position of the transducer based on the two positions.

ATTENTION: Be sure to purchase the appropriate
converter card for your absolute transduce device.

Homing VEL (user units/sec) = xxx
Return VEL (user units/sec) = xx
