Calculation mode for encoder's actual position (P-AXIS-00448)

P-AXIS-00448

Calculation mode for encoder actual position for additive encoder (PROFIdrive)

Description

If 1 is assigned to the parameter P-AXIS-00447 this parameter (P-AXIS-00448) specifies how the encoder's actual position is to be calculated. To this end, there are two modes.

Parameter

antr.profibus.encoder[i].read_abs_pos_mode

Data type

STRING

Data range

DRIVE_POS: The absolute position transferred by the encoder is adopted as the actual position after any necessary format adjustment (default).

COMBINED: Bits 31 … shift_xist1 are taken from the absolute position returned by the encoder, while bits 0 … shift_xist1 - 1 are taken from GX_XIST1.

See also the figure below.

Axis types

T, R, S

Dimension

T: ----

R,S: ----

Default value

DRIVE_POS

Drive types

Profidrive

Remarks

The COMBINED calculation mode may only be used if the drive's motor encoder returns an actual position that is absolute within one motor revolution.

If applicable, consult the manufacturer's documentation.
