Transfer reference position for drive-controlled homing to the drive (P-AXIS-00584)

P-AXIS-00584

Transfer reference position for drive-controlled homing to the drive

Description

When the parameter is set, the reference position stored in axis parameter P-AXIS-00152 can be transferred to the drive before the start of drive-controlled homing.

The sequence is then as follows:

  1. Read reference position stored in the drive.
  2. If the reference position read in and P-AXIS-00152 are not identical, P-AXIS-00152 is written to the drive, otherwise no action is taken.
  3. The reference position is again read from the drive and compared to P-AXIS-00152. If the reference position read is different from P-AXIS-00152, an error message ID70561 is output.

The ON_DRIVE_SIDE setting sets the reference position specified in P-AXIS-00152 directly in the drive. In contrast, the ON_CNC_SIDE mode takes into account a possible inversion of the direction of axis motion (P-AXIS-00230) or a coarsening of the encoder resolution (P-AXIS-00405) when writing,

Parameter

Data type

STRING

OFF

ON_DRIVE_SIDE

ON_CNC_SIDE (available as of V3.1.3081.06)

Axis types

T, R, S

T:----

R,S:----

Default value

OFF

Drive types

SERCOS, CANopen

Remarks

With SERCOS drives, the encoder used for homing is defined by reading SERCOS parameter S-0-0147. When Bit 0x08 is set in S-0-0147, the external encoder is used for homing. Consequently, S-0-0054 is used to write the reference point position; otherwise (homing to motor encoder) S-0-0052.

The parameter is available as of Build V3.1.3068.11.
