1. Outline

This manual describes the DDB (Direct Data Bus) function used to realize data input/output with a CNC while running a program developed with the user PLC ladder language. DDB includes the synchronous type (DDBS) and the asynchronous type (DDBA), but only the asynchronous type will be explained in this manual. DDB is a function that allows the PLC to directly read and write the various data in the CNC. By setting the information required for reading and writing into the buffer and calling out the DDB function, the PLC can set (write) the designated data into the CNC. Generally, the data is read and written in one piece units, but data related to the control axis can be processed for the designated number of axes. Features of this function include that the read data can be referred to in the step immediately following the execution of the DDBA command. This also applies to the written data. (Note that for the parameters, they may not be valid immediately after writing.)

This manual is organized in the following manner after the first chapter. Please refer to the required section for use.

(Note 1) The system designation is used when there is a multi-system specification. (Note 2) When reading and writing the axis data, if there is no axis designation or if the

designation exceeds the maximum control axes, the alarm "No. of axes illegal" will occur.

2.2.6 Read/write data (Rn+6, Rn+7 or Dn+6, Dn+7) (LOW) (HIGH)

When read is designated, the data designated by the PLC will be output by the CNC. When write is designated, the data to be written will be set by the PLC.

The valid area of the data will differ according to the data size. (Shaded area) When read is designated, a code will be added to the 1-byte and 2-byte data to create a 4-byte data size. Thus, even when reading 1-byte or 2-byte data, 4 bytes are required for the buffer size.

5. Explanation of Read/Write Data

5.3 Explanation of data details

The details of the data that are read or written with the DDB are explained below.

1-10 Maximum spindle speed (Gear 1st step to gear 4th step)

[Data definition]

[Data unit, range]

The data unit is r/min, and the setting range is 0 to 99999.

[Precaution]

After being set (written), this data is valid from the next spindle speed (S) command. However, the clamping operation with the maximum speed will be validated immediately.

1-11 Spindle limit speed (Gear 1st step to gear 4th step)

[Data definition]

This parameter is used to calculate the spindle speed (S-analog) data for each gear step. (This corresponds to the setup parameter, spindle parameter slimt 1 to 4.) The CNC determines the corresponding spindle limit speed with the spindle gear selection input (Y...) output from the PLC, and calculates the spindle speed (S-analog) data.

SOVRSd1d2d3d

Spindle speed data = x

slimt n 100

slimt n : Spindle limit speed of corresponding gear step determined with

spindle gear selection input. (n: 1~4) Sd1d2d3d4: Spindle speed (S) command SOVR : Spindle override

[Data unit, range]

The data unit is r/min, and the setting range is 0 to 99999.

[Precaution]

This setting is validated immediately after setting (writing).

- 20 -

5. Explanation of Read/Write Data

slimt n

ssift n

1-12 Spindle tap speed (Gear 1st step to gear 4th step)

[Data definition]

This parameter is for the maximum spindle speed during tapping (G68, G74, G84). The maximum spindle speed during normal operation follows the "1-10 Maximum spindle speed (Gear 1st step to gear 4th step)" setting, but a maximum speed parameter dedicated for tapping is provided during tapping (including synchronous tapping). (This corresponds to the setup parameter, spindle parameter stap1 to 4.) The CNC creates the spindle gear shift command 1 and 2 with the commanded S command and this parameter during tapping.

[Data unit, range]

The data unit is r/min, and the setting range is 0 to 99999.

[Precaution]

After being set (written), this data is validated from the next spindle speed (S) command during tapping.

1-13 Spindle shift speed (Gear 1st step to gear 4th step)

[Data definition]

The spindle motor is run slowly at a constant speed when changing the spindle gears to make the changeover operation smooth. This parameter is used to designate the speed at that time. (This corresponds to the setup parameter, spindle parameter ssift 1 to 4.) The CNC determines the corresponding spindle shift speed with the spindle gear selection input (Y...) output from the PLC.

Spindle speed data for gear shift =

slimt n : Spindle limit speed of corresponding gear step determined with

spindle gear selection input (n: 1~4) ssift n : Spindle shift speed of corresponding gear step determined with

spindle gear selection input

[Data unit, range]

The data unit is r/min, and the setting range is 0 to 32767.

[Precaution]

This setting is validated immediately after setting (writing).

5. Explanation of Read/Write Data

slimt n

sori

1-20 Spindle orient speed

[Data definition]

This parameter is used to rotate the spindle at a slow constant speed when carrying out spindle orientation (orient position stop). (This corresponds to the setup parameter, spindle parameter sori.)

Spindle speed data for orient =

sori : Spindle orient speed slimt n : Spindle limit speed of corresponding gear step determined with

spindle gear selection input (n: 1~4)

[Data unit, range]

The data unit is r/min, and the setting range is 0 to 32767.

[Precaution]

This setting is validated immediately after setting (writing).

[Supplement]

The orient function is provided for most of the recent spindle controllers, so this parameter is not used often for the spindle orientation.

1-21 Minimum spindle speed

[Data definition]

This parameter specifies the minimum spindle speed value. If the S command issued is a spindle speed lower than this parameter value or if the results of the spindle override are lower than this parameter value, the spindle will be rotated at this minimum spindle speed. (This corresponds to the setup parameter, spindle parameter smini.)

[Data unit, range]

The data unit is r/min, and the setting range is 0 to 32767.

[Precaution]

This setting is validated immediately after setting (writing).

1-50 Method selection parameter (1)

[Data definition]

The following parameters are indicated in bit units.

1-50-6) Synchronous tapping

This parameter is used when carrying out the machining program's tapping cycle (G84, G74) with the synchronous method.

0 : Asynchronous method 1 : Synchronous method

(This corresponds to the setup parameter, basic specification parameter set01.)

1-80 Method selection parameter (4)

[Data definition]

The following parameters are set in bit units.

[Data range]

The setting range is 0 to 255. The set data could affect the other bits, so take care when setting.

1-80-5) Reference point middle point ignore

This parameter designates how to handle the middle point during G28 and G30 reference point return.

0 : Move to the reference point via the middle point designated in the program. 1 : Ignore the middle point designated in the program, and move directly to the reference

point.

(This corresponds to the setup parameter, basic specification parameter Mpoint.)

5. Explanation of Read/Write Data

PGN

1-100 Position switches [1] to [8] (System 1, 2)

[Data definition]

A software dog switch is established at a designated point of the axis on the machine, and the output signal from this switch is output to the PLC interface when the axis passes over this switch. A maximum of eight switches can be set per system. This switch can be used after the zero point is established. (This corresponds to the setup parameter, position switches axis, dog1 and dog 2.)

The position switch uses the axis, dog1 and dog2 data as one set.

Axis : Name of axis for which switch is established. dog1 : Distance 1 from basic machine coordinate system zero point dog2 : Distance 2 from basic machine coordinate system zero point

The difference of dog1 and dog2 becomes the position switch width.

[Data unit, range]

The data unit is 1/2 of the machine constant input unit. The setting range is -99999.999 mm to +99999.999 mm.

[Precaution]

There will be a slight delay in the output signal changes in respect to the actual machine position. This maximum delay time (tmax) can be obtained with the following equation.

tmax = 0.06 - TP [sec]

TP : Position loop time constant ( [sec] )

2-10 Axis n No. 1 to No. 4 reference point coordinates

[Data definition]

The No. 1 reference point, No. 2 reference point, No. 3 reference point and No. 4 reference point using 0 of the basic machine coordinates as the base point can be set for each axis with these parameters. (This corresponds to the setup parameter, zero point return parameters G53ofs to #4_rfp.)

Basic machine coordinates

2-20 Axis n Movement control parameters

[Data definition]

The following parameters are set in bit units.

2-20-1) Inch output

This parameter indicates whether the output unit is a metric unit or inch unit. (This corresponds to the setup parameter, basic specification parameter iout.)

0 : When the machine side detectors (ball screw and detectors) are metric specifications.) 1 : When the machine side detectors (ball screw and detectors) are inch specifications.)

2-20-2) Reference point return direction (-)

This parameter indicates whether the reference point position is to the (-) direction or (+) direction from the reference point return near-point detection (near-point dog). (This corresponds to the setup parameter, zero point return parameter dir(-).)

5. Explanation of Read/Write Data

2-20-3) Servo OFF error compensation

The servo system will enter the servo OFF state when the servo OFF nth axis (*SVFn) signal is input from the PLC to the CNC. This parameter is used for each axis to set whether the amount that the motor rotated during servo OFF is to be returned to the original state when the servo is turned ON again. (This corresponds to the setup parameter, basic specifications parameter svof.)

0 : Compensate the error (Do not return to the original state.) 1 : Do not compensate the error

2-20-4) Rotary axis

This parameter indicates whether the target control axis is a linear axis or rotary axis.

0 : Linear axis 1 : Rotary axis

(This corresponds to the setup parameter, basic specification parameter rot.)

2-20-5) Motor CCW

This parameter indicates the motor rotation direction when commanded in the + direction.

0 : CW direction looking from motor load side 1 : CCW direction looking from motor load side

For + command For – command

Motor rotation direction definition (when parameter ccw = 0)

2-20-A) No reference point axis

This parameter indicates that the control axis is one that does not have a reference point or that reference point return is not required.

0 : G28, G29, G30, manual reference point return is carried out. 1 : G28, G29, G30, manual reference point return is ignored.

(This corresponds to the setup parameter, zero point return parameter noref.)

2-20-D) Diameter designated axis ..... Valid only for lathe system

This parameter indicates the movement amount (commanded with U) in the X axis direction to half of the command value. The command in address X will always be a diameter command.

0 : Addresses X and U command movement amounts are the same. 1 : The address U command movement amount is half of the address X movement amount.

(This corresponds to the setup parameter, basic specification parameter dia.)

[Data definition]

The various servo related information is expressed in bit units.

27-10-0) Ready ON

If the drive amplifier can be entered the ready ON state, including the ready ON request signal from the CNC, the main circuit will be turned ON. While the main circuit is ON, the ready ON signal will turn ON as the answer signal to the CNC. The conditions for turning OFF are as follows:

1) When the ready ON request signal from the CNC turns OFF.

2) When the CNC enters the emergency stop state.

3) When a servo alarm occurs.

27-10-1) Servo ON

When the above ready ON signal is ON and the servo ON request signal is received from the CNC, if the conditions provide that the servo can be turned ON, the servo ON signal will turn ON (a position loop will be structured). The servo ON signal will turn ON as the answer signal to the CNC while the position loop is structured. The condition for turning OFF is as follows:

1) When in addition to the conditions for the ready ON signal to turn OFF, the servo ON request signal from the CNC turns OFF.

27-10-2) In emergency stop

This is the signal answered by the drive amplifier when it receives notice that the CNC is in the emergency stop state. E7 will be displayed on the 7-segment display for drive amplifier diagnosis.

27-10-3) In alarm

This notifies that the drive amplifier is in the servo OFF state.

27-10-4) Z phase passing

This means that the reference point (Z phase) has been passed by the axis movement after the power was turned ON. The SPEC value of the servo parameters in the setup parameters determines which reference point (Z phase) is valid. The CNC will determine the zero point return position, etc., based on this signal. Once turned ON, this signal remains ON until it is turned OFF.

27-10-6) In-position

This indicates that the difference of the command and the feedback from the detector, or in other words, the position deflection (position loop droop) is within the range designated by ZRZ (in-position width) of the servo parameters in the setup parameters. How the CNC operates upon receiving this signal depends on inpos (in-position check valid) in the basic specification parameters of the setup parameters.

27-10-7) Torque limit

This notifies that the motor drive current has been limited. The current limit parameter will follow the ILMT (limit values for both + and – directions) in the servo parameters of the setup parameters.

5. Explanation of Read/Write Data

Reference point return

27-10-8) Smoothing 0

The acceleration/deceleration time constant for making the machine movement smooth is applied to the issued step-state command. The circuit onto which the acceleration/deceleration time constant is applied is called the smoothing circuit. Smoothing 0 means that there is no droop amount in that smoothing circuit.

(Note 1) This may turn ON when the machine is moving at an extremely low speed. (Note 2) This state is equivalent to when the plus motion (+) signal (MVPn) and the minus motion

(-) signal (MVMn) sent from the CNC to the PLC are both OFF.

27-10-9) Smoothing (+)

This indicates that there is a (+) droop amount (movement in the + direction) in the smoothing circuit described in section 27-10-8).

(Note 1) This may turn OFF when the machine is moving at an extremely low speed. (Note 2) This state is equivalent to the plus motion (+) signal (MVPn) sent from the CNC to the

PLC.

27-10-A) Smoothing (-)

This indicates that there is a (-) droop amount (movement in the – direction) in the smoothing circuit described in section 27-10-8).

(Note 1) This may turn OFF when the machine is moving at an extremely low speed. (Note 2) This state is equivalent to the minus motion (-) signal (MVPn) sent from the CNC to the

PLC.

27-10-C) Hardware OT+ (hardware overtravel)

This indicates that the stroke end (+) signal was input for an axis moving in the (+) direction. Once the conditions are established, the signal will turn ON and the axis will move in the (-) direction. And when the stroke end (+) signal is no longer input, this signal will turn OFF.

27-10-D) Hardware OT– (hardware overtravel)

This indicates that the stroke end (-) signal was input for an axis moving in the (-) direction. Once the conditions are established, the signal will turn ON and the axis will move in the (+) direction. And when the stroke end (-) signal is no longer input, this signal will turn OFF.

27-10-E) Near-point dog ON

This turns ON when the reference point return near-point detection signal (dog) for the axis is detected while executing the dog-type reference point return. This turns OFF when the reference point is reached.

[Data definition]

This is the load (current) of the feed axis motor.

Feed axis motor load (%) = Read data (An absolute value is retrieved.)

(Note) The same contents as the feed axis motor load A (27-30) are obtained for the feed axis

motor load B. To read the feed axis motor load, use the feed axis motor load A (27-30). Note that if the feed axis motor load B is used in a machine type that used the MR-S Series servo amplifier, the conversion calculation is not required.
