1. Program alarm (P/S alarm) alarm number

 

Alarm content:

000

For parameters that must be powered off after modification to take effect, power off should be done after parameter modification.

001

TH alarms, the program format of the peripheral input is wrong.

002

TV alarm, the program format of the peripheral input is wrong.

003

The input data exceeds the maximum allowable input value. Refer to the relevant content of the programming part.

004

The first character of the block is not an address, but a number or "-".

005

An address is not followed by a number, but another address or a block end character.

006

The symbol "-" is used incorrectly ("-" appears after an address that does not allow negative values, or two consecutive "-"s appear).

007

The decimal point "." is used incorrectly.

009

A character appears in a position where the character cannot be used.

010

An unusable G code was instructed.

011

A cutting feed rate is not given.

014

A synchronous feed command appears in the program (this machine does not have this function).

015

Attempt to move the four axes at the same time.

020

In the arc interpolation, the CNC professional micro signal cncdar, the difference between the starting point and the end point to the center of the circle is greater than the value specified by parameter No. 876.

021

During circular interpolation, the movement of an axis that is not in the circular interpolation plane was commanded.

029

The tool compensation value in the offset number specified by H is too large.

030

When using tool length compensation or radius compensation, the tool compensation value in the tool compensation number specified by H is too large.

033

An intersection point that cannot appear in tool radius compensation is programmed.

034

Circular interpolation appears at the start or cancel block of tool radius compensation.

037

Attempt to use G17, G18 or G19 to change the plane selection in the tool radius compensation mode.

038

Because in the tool radius compensation mode, the CNC professional micro-signal cncdar, the start or end point of the arc coincides with the center of the circle, so overcutting will occur.

041

Overcutting will occur during tool radius compensation.

043

An invalid T code was commanded.

044

Use G27, G28 or G30 commands in the canned cycle mode.

046

In the G30 instruction, the P address is assigned an invalid value (for this machine tool, it can only be 2).

051

An impossible movement occurred after the automatic corner cutting or automatic rounding block.

052

The block after the automatic corner cutting or automatic rounding block is not a G01 command.

053

In the automatic corner cutting or automatic rounding block, the address after the symbol "," is not C or R.

055

In the automatic corner cutting or automatic rounding block, the movement distance is less than the value of C or R.

060

When searching for the sequence number, the sequence number of the instruction was not found.

070

The program memory is full.

071

The searched address was not found, or the specified program number was not found during program search.

072

The number of programs in the program memory is full.

073

An attempt was made to use an existing program number when entering a new program.

074

The program number is not an integer between 1 and 9999.

076

There is no address P in the subroutine call instruction M98.

077

The subroutine nesting exceeds three levels.

078

The program number or sequence number commanded in M98 or M99 does not exist.

085

When the program is input by the peripheral, the input format or baud rate is incorrect.

086

When using the tape reader/puncher interface for program input, the peripheral ready signal is turned off.

087

When using the tape reader/puncher interface for program input, the CNC professional micro-signal cncdar, although the reading stop is specified, but after reading 10 characters, the input cannot be stopped.

090

The operation of restoring the reference point cannot be performed normally because the distance to the reference point is too close or the speed is too low.

091

Manual return to the reference point was performed when the automatic operation was suspended (there is a remaining amount of movement or when an auxiliary function is executed).

092

In the G27 command, the commanded position was found to be not a reference point after it was reached.

100

PWE=1, after prompting that the parameter modification is completed, set PWE to zero, and press the RESET key.

101

In the process of editing or inputting the program, the power is turned off when the NC refreshes the memory content. When this alarm occurs, you should set PWE to 1, turn off the power, and press and hold the DELETE key when you turn on the power again to clear the contents of the memory.

131

There are more than 5 PMC alarm messages.

179

The number of controllable axes set by parameter No. 597 exceeds the maximum value.

224

Attempt to execute a programmable axis motion instruction before returning to the reference point for the first time.

 

2. Servo alarm number

 

Alarm content:

400

The servo amplifier or motor is overloaded.

401

The speed controller ready signal (VRDY) is turned off.

404

The VRDY signal is not turned off, the CNC professional micro signal cncdar, but the position controller ready signal (PRDY) is turned off. Under normal circumstances, VRDY and PRDY signals should exist at the same time.

405

Error in the position control system. The return to the reference point failed due to a problem with the NC or servo system. Perform the operation of returning to the reference point again.

410

411

When the X axis is moving, the position error exceeds the set value.

413
