Axis parameters

P-AXIS-00003

Deceleration for an emergency stop

Description

The parameter defines the used deceleration for an emergency stop. If errors of error reaction class 4 occur, the NC decelerates at the rate for specific axes. The path then leaves the trajectory.

Remarks

When the parameter has the value 0, the value of P-AXIS-00008 (a_max) is used.

P-AXIS-00070

Axis number of master axis

Description

In the axis parameter list of the slave axis the logical number of its master axis is entered. If this parameter is assigned, the master and slave axes are assigned to one another during start-up. This so-called static gantry coupling exists at the position controller level. The slave axis is not known in the channel. A movement is only executed by programming their master axis.

Parameter

Data range

1 ≤ gantry_ax_nr ≤ MAX (UNS16)

Axis types

T, R

Dimension

T: ----

R: ----

Default value

0

Remarks

This entry is not adopted when the axis parameter list is updated. Updates only become effective when the controller is rebooted.

P-AXIS-00071

Non resettable path distance between master and slave axes

Description

Maximum permissible path distance between master and slave gantry axes. Error that cannot be remedied by NC reset.

P-AXIS-00074

Suppress homing for gantry slave axis

Description

This parameter can suppress the homing of gantry slave axes. When homing of the master axis is completed, the reference positions entered in the axis parameter lists of the slave axes are also adopted and monitoring of the gantry difference is started.

Parameter

BOOLEAN

Data range

0/1

----

Remarks

This parameter is not supported in the case of spindle axes.

P-AXIS-00075

Velocity of correction for compensation of gantry difference

Description

The parameter defines the velocity at which the axis position of the slave axis is corrected until the distance between master and slave is less than P-AXIS-00073 .

Parameter

Data type

UNS32

Remarks

 

P-AXIS-00249

Gantry difference monitoring before homing

Description

By default, the position difference between the gantry master and the slave axis is not monitored until both the master and the slave axes have been homed.

This parameter activates gantry difference monitoring before homing (gantry_diff_check_without_homing = 1). The parameters P-AXIS-00072 and P-AXIS-00071 are used as limits during monitoring. The offset between master and slave axis at the time of controller start-up is used for position offset instead of P-AXIS-00073 . On completion of homing, the parameter P-AXIS-00073 is used as position offset.

Parameter

kenngr.gantry_diff_check_without_homing

P-AXIS-00253

Drive-controlled homing of gantry axis (SERCOS)

Description

With drive-controlled homing (digital drives, SERCOS) the homing procedure is started synchronously for all gantry axes.

The user must also ensure that the homing parameter settings are the same for all drives.

Parameter

kenngr.gantry_synchronous_slave_homing

Data type

BOOLEAN

Data range

0/1

Axis types

T, R

Dimension

T: ----

R: ----

Default value

0

Drive types

SERCOS

Remarks

Drive-controlled homing must run identically for both drives (e.g. without cam and distance-coded measurement system). This must be initiated by corresponding parameters.

For safety reasons, torque can be reduced during the homing procedure.

P-AXIS-00254

CNC-controlled error reaction for gantry axes

Description

In case of an error, an intelligent drive executes an error reaction independently in most cases and reports this to the CNC. The CNC can then stop other axes in the gantry system running with an incorrect axis.

With gantry axes it is not allowed for one axis in the gantry system to stop independently. For this reason the CNC can execute a controlled stop of the complete gantry system in the event of an axis error. The function must be set for the master and the slave axes. A check is made whether the settings for master and slave axes are identical and as required, they are corrected in the slave axes.

Parameter

kenngr.cnc_controlled_stop_after_error

Data type

BOOLEAN

Data range

0: Drive-internal error reaction

1: CNC-controlled error reaction

Axis types

T, R

Dimension

T: ----

R: ----

Default value

0

Drive types

SERCOS, CANopen

Remarks

In the case of a CNC-controlled error response, the axis is stopped at the specified emergency stop acceleration
P-AXIS-00003 (a_emergency).

This parameter can be used with SERCOS and CANopen drives.

In addition a SERCOS drive must be parameterised so that it does not execute any independent (or only delayed) error response (see EcoDrive P-0-0117).

P-AXIS-00297

Default name of an axis

Description

The parameter defines the default name of the axis in the system and should therefore be unique system-wide in the same way as the logical axis number.

It is used for:

  • Name conflicts in connection with extended axis exchange operations [PROG//Section - Axis exchange commands].
  • In robotics in connection with the programming of axis-specific movements (P-CHAN-00253).

Besides this, the default name has no meaning because the axis name is defined in the channel configuration (P-CHAN-00006).

Parameter

kopf.log_achs_name

Data type

STRING

Data range

Maximum 16 characters (length of axis designation, application-specific)

Axis types

T, R, S

Dimension

T: ----

R,S: ----

Default value

X_Achse

Drive types

----

Remarks

The axis designations must begin with the letters A, B, C, U, V, W, X, Y, Z or Q. After that, all letters and digits are possible.

Caution: If the parameter P-CHAN-00253 is set, only the names ‘A1’ and ‘A32’ may be used.

P-AXIS-00704

Conditions for clearing the gantry difference

Description

This parameter determines the conditions for the clearance of the gantry difference.

Parameter

kenngr.gantry_on_mode

Data type

STRING

Data range

Mode

Meaning

DEFAULT

The gantry difference is cleared at reset or when the control unit 'gantry_on' ([HLI:]) is set.

ONLY_CONTROL_UNIT

The gantry difference is only cleared when the drive enables are set, the drive status is 'ready' and the control unit 'gantry_on' is set.

EDGE_TRIGGERED

The gantry difference is cleared on a rising edge of the control unit 'gantry_on'. The behaviour of this setting is equivalent to the behaviour of a set axis parameter P-AXIS-00261.

CONFIG :

Deactivates gantry control and prevents the clearing of a gantry difference.

Axis types

T, R, S

Dimension

T: ----

R,S: ----

Default value

DEFAULT

Drive types

----

Remarks

When the axis parameter P-AXIS-00261 is set, only DEFAULT or EDGE_TRIGGERED are used for P-AXIS-00704, otherwise the error message P-ERR-110606 is output.

The parameter is available as of V2.11.2034.02.
