ID 60162

Auto homing impossible, homing direction not identical with moving direction.

Description

Spindles have the option of so-called automatic homing. Here, as soon as a motion to an absolute position is programmed for the spindle, the spindle is first automatically homed without it being programmed in the NC program by a G74 command. See also [FCT-M1].

The direction of homing is defined by parameter P-AXIS-00158. This error message is output if the direction of spindle movement does not correspond to the one indicated in parameter P-AXIS-00158 at the start of automatic homing

For SERCOS drives automatic homing is not possible. This error message is shown in this case, too.

Solution

Class

Change the NC program so that the spindle moves in the direction defined in P-AXIS-00158 at the start of the homing direction.

Automatic homing can be suppressed by setting the bit NO_AUTO_RPF (value 0x0100) in parameter P-AXIS-00015. In this case, the spindle must be explicitly homed by a G74 command before moving to an absolute position.

See also [PROG// Section: Homing (G74)].

Parameter

%1:

Logical axis number (P-AXIS-00016) of the spindle.
