Products: ACR9000,9030,9040,9600,9630,9640
Feature added in OS: ACR90xx 1.28/IEC96xx 2.28. See also Senary Axis Flags
The AcroBasic command for homing an axis is JOG HOME. If an HMI or PC (ComACRserver) application wanted to initiate a home sequence, the app would need to send a string command. For example:
"AXIS0 JOG HOME 1"
In general sending ASCII string commands to the ACR is less efficient than setting a bit or parameter which uses a binary transfer method. To take advantage of the binary method, flags have been added for each axis to initiate homing.

| Jog Home Request | R/W | Initiates JOG HOME sequence for the axis with direction determined by Jog Home Direction Flag | |||||||
| Jog Home Direction | R/W | If flag is off, Jog Home Request will execute JOG HOME +1 sequence for the axis. If flag is set, Jog Home Request will execute JOG HOME -1 sequence. | |||||||
| Jog Home Request Failed | R | Flag is set if the request failed (could not even start), due to Kill All Motion or the axis is currently in motion | |||||||
