When servo system delay (by exponential acceleration/deceleration at

cutting or caused by the positioning system when a servo motor is used)

TOOL PATH AT

(a).

Time constant T₁ of the exponential acceleration/deceleration is fixed to

V₂

Programmed path

Tool path

V₁

Fig. D.3 (a) Slight deviation between the tool path and

the programmed path

This tool path is determined by the following parameters:

• Feedrate (V₁, V₂)

• Corner angle (q)

• Exponential acceleration / deceleration time constant (T₁) at

cutting (T₁ = 0)

• Presence or absence of buffer register.

The above parameters are used to theoretically analyze the tool path and

above tool path is drawn with the parameter which is set as an example.

When actually programming, the above items must be considered and

programming must be performed carefully so that the shape of the

workpiece is within the desired precision.

In other words, when the shape of the workpiece is not within the

theoretical precision, the commands of the next block must not be read

until the specified feedrate becomes zero. The dwell function is then used

to stop the machine for the appropriate period.

Analysis

The tool path shown in Fig. D.3 (b) is analyzed based on the following

conditions:

Feedrate is constant at both blocks before and after cornering.

The controller has a buffer register.

(The error differs with the reading

speed of the tape reader, number of characters of the next block, etc.)

The initial value when cornering begins, that is, the X and Y coordinates

APPENDIX

B-64124EN/01

D.4

When a servo motor is used, the positioning system causes an error

between input commands and output results. Since the tool advances

RADIUS DIRECTION

along the specified segment, an error is not produced in linear

ERROR AT CIRCLE

interpolation. In circular interpolation, however, radial errors may be

CUTTING

produced, sepecially for circular cutting at high speeds.

This error can be obtained as follows:

Command path

Actual path

Dr +

(T₁₂ ) T₂₂(1 * a²))^V2

(1)

: Maximum radius error (mm)

v : Feedrate (mm/s)

: Circle radius (mm)

T₁

: Exponential acceleration/deceleration time constant (sec)

at cutting (T=0)

T₂

: Time constant of positoning system (sec). (Inverse of positon

loop gain)

: Feed forward coefficient (%)

In the case of bell-shaped acceleration/deceleration and linear acceleration/

deceleration after cutting feed interpolation, an approximation of this radius

error can be obtained with the following expression:

Linear acceleration/deceleration after cutting feed interpolation

Dr + ǒ 1

24^T12 )2T22(1*a2)Ǔ

Bell-shaped acceleration/deceleration after cutting feed interpolation

Dr + ǒ 1

48^T12 )2T22(1*a2)Ǔ

Thus, the radius error in the case of bell-shaped acceleration/deceleration

and linear acceleration/deceleration after interpolation is smaller than in

case of exponential acceleration/deceleration by a factor of 12, excluding

any error caused by a servo loop time constant.

Since the machining radius r (mm) and allowable error ∆r (mm) of the

workpiece is given in actual machining, the allowable limit feedrate v

(mm /sec) is determined by equation (1).

Since the acceleration/deceleration time constant at cutting which is set

by this equipment varies with the machine tool, refer to the manual issued

by the machine tool builder.

SRAM CORRECTABLE ERROR

The SRAM correctable error cannot be corrected.

Cause:

A memory problem occurred during memory initialization.

Action:

Replace the master printed circuit board (SRAM module).

5227

FILE NOT FOUND

A specified file is not found during communication with the built-in

Handy File.

5228

SAME NAME USED

There are duplicate file names in the built-in Handy File.

5229

WRITE PROTECTED

A floppy disk in the built-in Handy File is write protected.

5231

TOO MANY FILES

The number of files exceeds the limit during communication with the

built-in Handy File.

5232

DATA OVER-FLOW

There is not enough floppy disk space in the built-in Handy File.

5235

COMMUNICATION ERROR

A communication error occurred during communication with the built-in

Handy File.

5237

READ ERROR

A floppy disk in the built-in Handy File cannot be read from. The floppy

disk may be defective, or the head may be dirty. Alternatively, the Handy

File is defective.

5238

WRITE ERROR

A floppy disk in the built-in Handy File cannot be written to. The floppy

disk may be defective, or the head may be dirty. Alternatively, the Handy

File is defective.

G41/G42 NOT ALLOWED IN MDI

G41/G42 (cutter compensation C: M series, tool-nose radius com-

MODE

pensation: T series) was specified in MDI mode. (Depending on the set-

ting of bit 4 of parameter No. 5008)

5303

TOUCH PANEL ERROR

A touch panel error occurred.

Cause:

1. The touch panel is kept pressed.

2. The touch panel was pressed when power was turned on.

Remove the above causes, and turn on the power again.

5306

MODE CHANGE ERROR

In an one-touch macro call, the mode is not normally switched at the

beginning.

5311

FSSB : ILLEGAL CONNECTION

1. This alarm is issued if, in a pair of axes in which one axis has an

odd servo axis number (parameter No. 1023) and the other has an

even servo axis number that is adjacent to the odd servo axis

number, one of the axes is assigned to an amplifier connected to

an FSSB in a system different from that for the other axis.

2. This alarm is issued if the system does not satisfy a constraint for

performing high-speed HRV control, current control periods for

two FSSBs are different, and it is specified that pulse modules

connected to an FSSB in different paths are to be used.
