Active homing in "BERO and zero mark" mode
When you start homing with the "MC_Home" command, the axis first approaches
the BERO (homing cam) and secondly the referencing zero mark, according to the
axis configuration. The diagram shown in the lower section of the figure shows the
resultant motion profile.
Meaning of the various parameters:
Parameter Value Description
Homing required Yes The axis must be homed in order to execute
absolute motion commands.
No The axis must not be homed in order to
execute absolute motion commands.
Homing mode For this homing mode:
Homing mode: "BERO and zero mark"
Zero mark Before
BERO
The axis is homed to the zero mark which lies,
with reference to the direction of the reference
point approach, before the BERO
After BERO The axis is homed to the zero mark which lies,
with reference to the direction of the reference
point approach, after the BERO
Start reference point
approach
Positive
direction
Reference point approach in positive direction.
Negative
direction
Reference point approach in negative
direction.
Logical address of the BERO [byte
address]
Logical byte address of the BERO. The BERO
can be connected to the integrated inputs of
the Technology CPU, or to the I/O on
DP(DRIVE).
Bit number [number of
the bit]
Bit address of the signal used for BERO.
