Configuration of the load gear (p2720).
The following points can be set by configuring this parameter:
● p2720.0: Activation of position tracking
● p2720.1: Setting the axis type (linear or rotary axis)
● p2720.2: Reset position
Note
If position tracking of the load gear is activated with parameter p2720[0]=1 (position gear
load tracking) after the encoder is adjusted (p2507=3), the adjustment will be reset.
If the encoder is adjusted again when load position tracking is active, the load gear position
will be reset (overflows).
The permissible position tracking range is mapped onto the reproducible encoder range of
EPOS.

Here, a rotary axis refers to a modulo axis (modulo offset can be activated through
higher-level control or EPOS). With a linear axis, position tracking is mainly used to
extend the position area (see section: Virtual multiturn encoder (p2721)).
The position values stored in non-volatile memory are reset in response to the following
events:
– When encoder replacement is detected.
– When the configuration of the encoder data set (EDS) is modified.
– When the absolute encoder is adjusted again.
