Fundamentals
Why reference?
The control must be synchronized with the position measurement system of each machine axis so that the control can detect
the exact machine zero when it is switched on. This process is known as referencing.
The spindle process (synchronizing) is largely described in Chapter "Spindle (S1) (Page 156)".
Position measurement systems
The following position measuring systems can be mounted on the motor:
● Incremental rotary measuring system
● Absolute rotary measuring system
The referencing for the mounted position measuring systems can be set with MD34200 ENC_REFP_MODE ("REF.PIOINT"
mode).
Output cam
An output cam for referencing may be required for linear axes, and its signal has the following tasks:
● Selection of the direction of travel when approaching the zero mark (synchronized pulse)
● Selection of the zero mark, where required.
BERO
A BERO (inductive proximity switch) can be deployed as the encoder for the synchronized pulse (instead of the zero mark of
the position encoder) (preferred for rotary axes, spindles). Here connection is made to the control system via pin6 (DI3) of
terminal X21.
