2.6 Mechanical Homing
2.6.1 Mechanical Homing modes
In all positioning systems there is a requirement to be able to find a mechanical zero po-
sition after the system is powered up or at specific times during operation. For this pur-
pose the MAC motor offers 5 different Homing modes which can be selected in the
MacTalk main window or by sending a command at one of the serial interfaces.
The 5 different Homing modes can in addition be selected to be started automatically af-
ter power up of the motor or done by sending a command during normal operation to
the motor.
The menu offers 11 choices:

Select the Homing mode
using this field. The selected format will
be used as follows :
- Immediately after the motor is powered up
(only the “Power up ....” Formats)
- If a search is initiated via the serial
interface or
- From an expansion module (MAC00-R1,
R4, -FP4, EC4 etc.).
Please note that the 3 formats for
“Power up” Homing must not be
selected if an expansion module is used
(MAC00-R1, R3 or FP2). If an automatic
Homing after “Power up” is required
when using one of these modules, the
function must be enabled on the product tab
for the actual module. (See also the chapters
describing the expansion modules)
