2.2 Homing/synchronizing
Why synchronize?
In order to ensure that the control detects the exact position when it is switched on, the
control must be synchronized with the position measurement system of the spindle. This
process is known as synchronization.
Only a synchronized spindle is capable of:
Thread cutting
Rigid tapping
Being programmed as an axis
Further explanations regarding synchronization of the spindle can be found under:
Literature:
/FB1/ functions manual Basic Functions; Reference Point Travel (R1)
Why reference?
In order to ensure that the control detects the exact machine zero when it is switched on, the
control must be synchronized with the position measurement system of the rotary axis. This
process is known as homing. The sequence of operations required to home an axis is known
as homing.
Only a homed axis can approach a programmed position accurately on the machine.
Further explanations regarding referencing of round axis can be found under:

Installation position of the position measurement system
The position measurement systems can be installed as follows:
Direct on the motor in combination with a Bero proximity switch on the spindle as a zero-
mark encoder
On the motor via a measuring gearbox in combination with a Bero proximity switch on the
spindle as a zero-mark encoder
Directly on the spindle
On the spindle via a measuring gearbox in combination with a Bero proximity switch on
the spindle as a zero-mark encoder (only with ratios not equal to 1:1)
Where two position measurement systems are provided, they can be installed either in the
same location or separately.
