In this chapter you can read about:
Positioning after homing run .......................................................................................... 113
Absolute encoder .......................................................................................................... 114
Operation with MultiTurn emulation ............................................................................... 114
Machine zero modes overview ...................................................................................... 115
Homing modes with home switch (on X12/14) ............................................................... 117
Machine zero modes without home switch ..................................................................... 123
Adjusting the machine zero proximity switch .................................................................. 128
Machine zero speed and acceleration ........................................................................... 128
The Compax3 machine zero modes are adapted to the CANopen profile for Motion
Control CiADS402.
Essentially, you can select between operation with or without machine reference.
The reference point for positioning is determined by using the machine reference
and the machine reference offset.
Machine reference run
In a homing run the drive
normally
(see on page 113) moves to the position value
0 immediately after finding the home switch. The position value 0 is defined via the
homing offset.
A machine reference run is required each time after turning on the system for
operation with machine reference.
Please note:
During homing run the software end limits are not monitored.
