1009 NADFV PMCE MCC ZNDPx PDIAx RDA2x ISEx RCAx

Parameter input Data type : Bit axis

RCAx Specifies whether the axis is controlled in the HPCC mode.

0 : The axis is not controlled in the HPCC mode. 1 : The axis is controlled in the HPCC mode. (used with 64–bit RISC) Set 1 in this parameter for an axis to be controlled in the HPCC mode. If the state of the axis–by–axis

interlock signal (*ITLn) or axis–by–axis machine lock signal (MLKn) is changed in the HPCC mode (set with G05P10000) for an axis having this parameter set to 0, the change is ignored.

If the axis–by–axis interlock signal goes low or the axis–by–axis machine lock signal goes high for an axis having this parameter set to 1, the interlock function or machine lock function is activated for all axes controlled in the HPCC mode.

This means that the interlock function and machine lock function cannot be activated for each axis separately in the HPCC mode.

ISEx Specifies the increment system for each axis (IS–E)

0 : The set value is displayed on the workpiece reference position offset setting menu. 1 : The set value is not displayed on the workpiece reference position offset setting menu.

NOTE 1 This parameter also determines whether to display the set value on the workpiece reference

position offset setting menu of the multi-submenu.

NOTE 2 This function is not available in Series 15–MB(MA2).

MCC Specifies the behavior of the servo amplifier MCC signal in an axis–detached state as follows:

0 : turned off 1 : not turned off If an axis is detached when this parameter is 1, the servo motor is de–energized, but the servo amplifier

MCC signal is not dropped. Even if one axis is detached in a two–axis amplifier configuration, this function suppresses alarm SV013, ”IMPROPER V–READY OFF” for the other axis.

If a cable connecting a servo system and the CNC (command cable or feedback cable) is removed for a detached axis, however, the SV013 alarm occurs for the other axis. In a fully closed system, the SV013 alarm may also occur for that axis. These symptoms occur because of the characteristic of a multi–axis amplifier such as two–axis or three–axis amplifier.

NOTE 1 Regardless of the state of this parameter (bit 5 of data No. 1009), it is necessary to cause a

return to the reference position for a detached axis before a move command is issued. Otherwise, alarm PS181, ”ZERO RETURN NOT FINISHED” will occur , prompting for a return to the reference position.

NOTE 2 This function cannot be used for a system with an absolute position detector (bit 5 of parameter

No. 1815 = 1).

NOTE 3 For a system not using a 2–axis amplifier, it is always necessary to reset bit 5 (MCC) of

parameter No. 1009 to 0.

NOTE 3 There are three possible axis arrangements. The user should be familiar with the axis

arrangements, because they have considerable bearing on the display of data for each axis or on the signal connection between the NC and power magnetics cabinet. In the following explanation, synchronization control refers to a function supported only for multiaxis control.

(1) Input axis arrangement

The input axis arrangement is used for part–program specification and jog feed commands. A synchronization control axes or tandem control axes is regarded as a single axis. Overtravel, interlock, and other signals are connected according to this arrangement.

(2) Axis arrangement for setting and displaying data for each axis

This axis arrangement is used when parameters and diagnostic data are displayed on the CRT screen. When a synchronization control axis or tandem control axis is provided, a slave axis is added subsequent to the input axis arrangement. When multiple synchronization control axes and tandem control axes are provided, slave axes must be arranged in order of their master axes in the input axis arrangement.

(3) Drive axis arrangement

This axis arrangement is used to connect servo motor signals and NZ (near zero) signals (for multiaxis control only). The servo axis arrangement is determined by parameter No. 1023. Specify the synchronization control and tandem axes as follows:

1023 Servo axis number of each axis

Parameter input Data type : Byte V alid range : 1 to (number of control axes) Specify the number of the servo axis that corresponds to each control axis. Normally, set each servo and control axis to the same numbers. For example, when using the spindle positioning function (indexing) with axis C, add 16 to the servo axis num-

ber to get the parameter value.

Example How to calculate parameter value for C

When there are X, Z, and C(C):

16 + 3 = 19 (set parameter to 19)

When there are X, Z, Y, and C(C):

16 + 4 = 20 (set parameter to 20)

The control axis number and servo axis number of an axis with an absolute position detector must be the same.

1025

Parameter input Data type : Byte axis Usually , spline interpolation is performed on the three basic axes, X, Y, and Z. It can also be performed on a

rotary axis (axis for which parameter No. 1022 is 0). In this case the rotary axis substitutes for the basic axis specified using this parameter. This setting is used to determine which of the I, J, K, P, Q, and R addresses is to be used for the rotary axis when the first– and second–order differential vectors are specified at the beginning of spline interpolation.

Settings:

1 : The rotary axis is assumed to be the X–axis. So, the first– and second–order differential vectors are

specified using I and P.

2 : The rotary axis is assumed to be the Y–axis. So, the first– and second–order differential vectors are

specified using J and Q.

3 : The rotary axis is assumed to be the Z–axis. So, the first– and second–order differential vectors are

specified using K and R.

Example

When spline interpolation is performed for X, Y, and C, this parameter should be set to 3 for the C–axis.

This function compares the absolute difference of the feedrate components (if the tool does not move along a certain axis, the feedrate component is 0 along the axis) along each axis in block A and B with the value set in parameter 1478. If absolute difference in the feedrate components for even one of the axes exceeds the value set in parameter 1478, this function automatically decelerates the machine at the end of block A. When the decelerated feedrate in the acceleration/deceleration circuit of each axis drops below the value set in parameter 1479, cutting proceeds to the next block (block B).

The residual pulses left in the acceleration/deceleration circuit of the X axis at time t are shown by the shadowed portion. However , because the decelerated feedrate in the acceleration/ deceleration circuit of the X axis has dropped below the value preset in this parameter, cutting proceeds to the next block.

The feedrate component of each axis, in the case of a linear interpolation block, is the tangential feedrate along the axis obtained by multiplying the override by the feedrate specified in that block. In the case of a circular interpolation block, the feedrate component of each axis is the tangential feedrate along the axis obtained by multiplying the override by the feedrate specified in that block at the start point (block B) or end point (block A). The override here refers to feedrate override being selected at the time when the information of the block is read.

If feed per rotation (G95) or feed at the feedrate specified by the F code with a one–digit number is specified in block A or B, no check is made to see if automatic corner deceleration is necessary .

In dry run mode, checks are made to see if automatic corner deceleration is necessary , just as during normal operation.

Parameter input Data type : Word Unit of data : 0.01% V alid data range : 0 to 9900 Specify the minimum value of the feed–forward factor determined during calculation by automatic tuning. The automatic tuning function sets the feed–forward factor to the minimum value when the calculated feed–for-

ward factor is lower than the minimum value. This parameter has a default value of 9400 during automatic setting.

Whenever a finishing level higher than the determined level is specified after the lower limit has been specified, the feed–forward factor is set to the minimum value. In such a case, the same time constant after interpolat ion is obtained because it is calculated using the minimum feed–forward factor. Therefore, automatic calculation may produce the same result for different finishing levels. In this case, specify 0 in this parameter and ret ry automatic tuning.

Parameter input Data type : Bit

CVR Specifies whether to issue a servo alarm if velocity control ready signal VRDY turns on before position

control ready signal PRDY turns on. 0 : Does not issue a servo alarm. 1 : Issues a servo alarm. Normally, set CVR to 1.

FVF Specifies whether to perform follow–up in the servo off mode.

– 78 –

B–62560E/03 4. DESCRIPTION OF PARAMETERS

0 : Does not perform follow–up (mechanical clamp in the servo off mode). 1 : Performs follow–up (mechanical handle in the servo off mode).

RTFWD

0 : Disables forward feed control during rapid traverse. 1 : Enables forward feed control during rapid traverse. Normally , forward feed control is enabled only when cutting feed is performed. When this parameter

is set to 1, forward feed is also enabled during rapid traverse. This decreases positional deviation in the servo, reducing the time for entering an effective area during positioning.

CCI Specifies the value to be used as the effective area during cutting feed (cutting–feed effective area).

0 : Uses parameter 1827, which is also used for rapid traverse. 1 : Uses parameter 1838, which is used only for cutting feed.

When a positioning block is specified or an exact stop is specified in a cutting feed block, the block decelerates the tool at the end of the block for a position check. The cutting/rapid traverse position check function al lows the effective area (parameter 1838) to be set separately for cutting feed in addition to the effective area (parameter 1827) for rapid traverse.

For example, a larger effective area can be set for rapid traverse, while an ordinary small effective area is set for cutting feed. This can reduce machining time (positioning time) without reducing machining precision.

The CCI bit of parameter 1800 is used to select whether this new function or the standard position check function is used. When this position check function is selected, it is effective for all axes. For axes that do not require this function, set the same data in parameters 1827 and 1838.

When a rapid traverse block terminates, a position check is performed using the value set in rapid–traverse– specific parameter 1827. When a cutting feed block terminates and the next block specifies cutting feed, a position check is performed using the value set in cutting–specific parameter 1838; if the next block specifies rapid traverse, however , a position check is performed using the value in rapid–traverse–specific parameter 1827. Furthermore, when a cutting feed block terminates, cutting–specific parameter 1838 can always be used for a position check regardless of the next block. This is specified by the CIN bit of parameter 1800.

Upon termination of a cutting feed block, the effective area is determined as follows:

CIN bit (bit 5) of parameter 1800

0 Rapid traverse data (1827) Cutting feed data (1838) 1 Cutting feed data (1838) Cutting feed data (1838)

In addition, the RTFWD bit of parameter 1800 enables forward feed for rapid traverse. When forward feed control is enabled for rapid traverse, positional deviation in the servo is decreased and the time required for enterin g the effective area during positioning is reduced.

CIN When CCI is 1, the CIN bit specifies the condition under which the cutting feed parameter defines the

cutting–feed effective area. 0 : Used only when the next block specifies cutting feed. 1 : Always used regardless of the next block.

Valid range : 0 to 99999999 Specify the positioning deviation limit for a drilling axis in the rigid tapping mode. (Parameter No. 1828 is used

for axes other than a drilling axis in the rigid tapping mode.) Specify the same loop gain for the drilling axis and spindle in the rigid tapping mode. The setting of parameter

No. 5753 is used as the loop gain for the drilling axis and spindle in the rigid tapping mode. The loop gain of the spindle must not be excessively large. In addition, the loop gain of the drilling axis in the rigid tapping mode is generally smaller than the loop gain in other modes (parameter No. 1828). The positioning deviation limit for the drilling axis while the tool is moving in the rigid tapping mode is provided separately because the positioning deviation increases if the loop gain decreases at the same speed.

1849 Backlash compensation amount used for rapid traverse for each axis

Parameter entry Data type : Word axis type Unit of data : Detection unit V alid data range : –9999 to +9999 Set the backlash compensation amount used in rapid traverse for each axis.

NOTE This parameter is valid when RBK, #6 of parameter 1804, is set to 1.

More precise machining can be performed by changing the backlash compensation amount depending on the feedrate, rapid traverse or the cutting feed for positioning.

Let the measured backlash at cutting feed be A and the measured backlash at rapid traverse be B. The backlash compensation amount is shown below depending on the change of feedrate (cutting feed or rapid traverse) and the change of the direction of movement.

NOTE 1 α=(A–B)/2 NOTE 2 The positive direction for compensating values is the direction of movement.

NOTE 3 Assign the measured backlash at cutting feed (A) in parameter No. 1851 and that at rapid

traverse (B) in parameter No. 1849

NOTE 4 Manual continuous feed is regarded as cutting feed. NOTE 5 The backlash compensation depending on feedrate is not performed until the first return to the

reference position is completed after the power is turned on. Until then, the normal backlash compensation is performed according to the value specified in parameter No. 1851 irrespective of the feedrate.

NOTE 6 The backlash compensation depending on feedrate is performed only when RBK, #6 of

parameter No. 1804, is set to 1. When RBK is set to 0, the normal backlash is performed.
