TESTING A PROGRAM

Overview

Before machining is started, the automatic running check can be executed. It checks whether the created
program can operate the machine as desired. This check can be accomplished by running the machine or
viewing the position display change without running the machine.

5.3.1

Machine Lock

Overview

The change of the position display can be monitored without moving the machine. When all-axis machine
lock signal MLK, or each-axis machine lock signals MLK1 to MLK8 are set to 1, output pulses (move
commands) to the servo motors are stopped and the machine coordinates are not updated in manual and
automatic operation. The commands are distributed, however, updating the absolute and relative
coordinates. The operator can therefore check if the commands are correct by monitoring the position
display.

Explanation

Automatic operation in the machine lock state (M, S, T, and B commands)

Machine lock applies only to move commands along controlled axes. Updating modal G codes or setting
a coordinate system is performed normally. M, S, T, and B (2nd auxiliary function) commands are also
performed normally.

Turning on/off the machine lock signal during movement along an axis

When the machine lock signal for an axis is set to 1 during movement along the  axis that is not in the
machine lock state, the axis is immediately placed in the  machine lock state and output pulses (move
commands) to the servo motor are  stopped. The tool is decelerated and stopped with the automatic
acceleration/deceleration function.
On the other hand, when the machine lock signal for an axis is set to 0 during distribution of the move
command along the axis in the machine lock state, pulse  (move command) output for the axis is
immediately restarted. The tool is accelerated with the automatic acceleration/deceleration function.

Machine lock shift value

When a move command is executed in the machine lock state after once the workpiece coordinate system
is fixed, the workpiece coordinate system is shifted from the machine coordinate system because machine
coordinates are not updated. This shift amount is called a machine lock shift value. Diagnosis data
No.4104 indicates the machine lock shift value.
The machine lock shift value is cancelled by the manual reference position return or the workpiece
coordinate system preset operation.

Machine lock shift value check in automatic operation

If bit 2 (MSC) of parameter No.11501 is 1, when the workpiece coordinate system is shifted by the axis
movement in the machine lock state, the alarm PS5559"ILL. AXIS OPERATION (COORD SYS)" is
issued. This can prevent forgetting to cancel the shift value by the manual reference position return and
the workpiece coordinate system preset operation after the machine lock is released.

Coordinate position display screen

When a machine lock is being applied to an axis, “L” appears on the left side of the axis address of the
axis on the coordinate position display screen.

Limitation

Outputting the movement state of ax axis

Axis moving signals MV1 to MV8 <Fn102> are useful in the machine lock state.
Axis moving direction signals MVD1 to MVD8 <Fb106> are useless in the machine lock state. These
signals maintain their condition before the machine lock.

5. AUTOMATIC OPERATION

B-64693EN-1/01

- 828 -

Reference position return (G27, G28, and G30)

When the reference position return command (G28), or 2nd to 4th reference position return command
(G30), is executed for an axis in the machine lock state, in motion to middle point, distribution and
position updating are performed. The tool, however, is not returned to the reference position. The
reference position return completion signals (ZP1 to ZP4) are not output.
The reference position return check command (G27) is ignored in the machine lock state.

Selecting a machine coordinate system (G53)

When a positioning of machine coordinate system (G53) is specified in the machine lock state, move
commands are invalid and absolute coordinates and relative coordinates are not updated.
When machine lock is applied during G53 movement, output pulses (move commands) to the servo
motors are stopped and machine coordinates are not updated. The absolute and relative coordinates are
updated.

High precision oscillation function

Do not switch machine lock signal to the oscillation axis during oscillation motion, otherwise an alarm
PS5050 "ILL-COMMAND IN G81.1 MODE" is issued.

Manual intervention and return

Do not perform manual intervention in the machine lock state, otherwise the tool might move to wrong
position in return operation.

Tool retract and recover

Do not perform manual retraction in the machine lock state, otherwise the tool might move to wrong
position in recovery.

Program restart / Quick program restart

The tool cannot be returned to a correct position under the following conditions.
-

Manual operation is performed in the machine lock state.

When program restart is specified in the machine lock state, then the machine lock is canceled.

Type for counting time of tool management function

The count-up operation is not performed in the machine lock state.

High-speed program check function

During the high-speed program check mode, all-axis machine lock signal MLK and each-axis machine
lock signals MLK1 to MLK8 are invalid except for PMC control axis.

PMC axis control

When bit 0 (MLE) of parameter No.8001 is 1, all-axis machine lock signal MLK and each-axis machine
lock signals MLK1 to MLK8 are invalid for PMC-controlled axes. However, each-axis machine lock
signals MLK1 to MLK8 become valid by setting bit 1 (MLS) of parameter No.8006 to "1".
All-axis machine lock signal and each-axis machine lock signals are invalid in the following command
irrespective of setting parameter MLE and MLS.
-

Speed command

Torque control command

Balance cutting

Balance cutting is not performed in the machine lock state.

Each-axis machine lock

In some functions (e.g., synchronous control, coordinate system rotation), axes which are not specified
move. And relationships between each-axis machine lock signals and effecting axis are various ways.
1

In the following functions, each-axis machine lock signals effect to output pulses (move commands)
after conversion.
-

Coordinate system rotation

3-dimentional coordinate conversion

Tilted working plane indexing

In arbitrary angular axis control, each-axis machine signals are applied to move commands specified
in the Cartesian coordinate system (the program coordinate system).
When each-axis machine lock signal is applied to the perpendicular axis, machine lock is valid to a
movement of the perpendicular axis by specifying the perpendicular axis, but invalid to a movement
of the perpendicular axis by specifying the angular axis.
When each-axis machine lock signal is apply to the angular axis, machine lock is valid to the
movement of the perpendicular axis and the angular axis by specifying the angular axis.

Dry Run

Overview

Dry run is valid only for automatic operation.
The tool is moved at a constant feedrate regardless of the feedrate specified in the program. This function
is used, for example, to check the movement of the tool without a workpiece.

CAUTION

This feedrate depends on the specified parameters, the manual rapid traverse
switching signal (RT), manual feedrate override signals (*JV0 to *JV15), and
whether the command block specifies rapid traverse or cutting feed, as listed in
the table below.

Single Block

Overview

Single block operation is valid only for automatic operation.
When the single block signal (SBK) is set to 1 during automatic operation, the CNC enters the automatic
operation stop state after executing the current block. In subsequent automatic operation, the CNC enters
the automatic operation stop state after executing each block in the program. When the single block signal
(SBK) is set to 0, normal automatic operation is restored.
Single block operation during the execution of custom macro statements depends on the setting of bits 5
(SBM) and 7 (SBV) of parameter No. 6000, as follows:
SBM=0, SBV=0 : Operation does not stop in the custom macro statements but stops once the next NC

command has been executed.

SBM=1 : Operation stops after each block in the custom macro statements.
