Spindle Orient

Commanding a Spindle Orient

M19 M Code

You can command an orient using the M19 M code or by invoking the spindleorient.mcs macro.

 

M19 [S<stopping_angle>]

Orient the spindle and move it to the specified angle. If no angle is specified, 0 is used.

UserGUIModule.m19( hVars )

This hook script is invoked (if it exists) before the M19 M code begins the orient process.

It is a standard MachMotion hook function.

spindleorient Macro

spindleorient( [<stopping_angle>[, <orient_direction>]] )

This is the macro Mach 4 invokes when performing a spindle orient (e.g. for a tool change).

UserGUIModule.spindleorient( [<stopping_angle>[, <orient_direction>]] )

This hook script is invoked (if it exists) before the orient is attempted. It is a standard MachMotion hook function.

UserGUIModule.MacroOrient()

This hook script is invoked (if it exists) at the beginning of the macro orient process.

It is a standard MachMotion hook function.

UserGUIModule.spindleorientcancel()

This hook script is invoked if a spindle orient is cancelled, before any automatic cancellation behavior takes place.

It is a standard MachMotion hook function.

UserGUIModule.MacroOrientCancel()

This hook script is invoked if a spindle orient is cancelled, before any automatic cancellation of macro orient behavior takes place.

It is a standard MachMotion hook function.

Spindle Orient (MachMotion User Command)

There is a user command named Spindle Orient, that can be invoked (e.g. assigned to a function button) that invokes the spindleorient macro.

Configuration

There are a number of configurable parameters for orienting the spindle.

MachMotion Parameters

Spindle Orient Type

Manual

When an orient is commanded, the spindle will be free to move and must be oriented by the operator physically rotating it to the correct position.

Auto

When an orient is commanded, the CNC software will perform an orient routine, waiting until it is complete.

Spindle Orient Macro Sensor Timout

the timeout (in milliseconds) used to wait for an orient operation to complete

Spindle Orient Syle

PLC

The orient is performed by invoking PLC sequence #50.

Macro

The orient is performad by the module/macro code.

Spindle Orient Macro Output

The output set to start the orient.

Spindle Orient Macro Input

The input waited on that indicates that the orient is complete.

Spindle Orient Control Mode

Spindle On

The spindle is commanded forward while orienting.

Spindle Stop

The spindle is commanded to stop before attempting to orient, but doesn't wait for it to be stopped before proceeding.

Spindle Stop Wait

The spindle is stopped before attempting to orient, waiting for the stop before attempting the orient.

Spindle Stop Start

The spindle is stopped before attempting to orient, then commanded forward while orienting.

Spindle Orient Speed

When using Spindle On or Spindle Stop Start control modes, this is the speed to which the spindle is commanded while orienting.

 

For example, if using a PLC, these are common Orient settings:

Wiring

If using a PLC for pin lock orient, the PLC must be able to command the VFD to stop immediately. Wire the PLC to a Fast Stop input on the VFD.
