P-AXIS-00723 | Default value of data element after controller start-up | |
Description | When cyclic communication is used (see P-AXIS-00720), this parameter defines the value of the telegram element after controller start-up. This parameter is also used if reading the current value at the start of motion to fixed stop is not required (see P-AXIS-00730). At the end of the move to fixed stop function, the controller writes this value back to the drive. | |

drive types. | SERCOS, CANopen | |
Remarks | This parameter must be assigned if the data item is transferred cyclically, i.e. the parameter P-AXIS-00720 has the value CYCLIC or reading the active parameter value is suppressed, i.e. P-AXIS-00730 has the value 1. | |
P-AXIS-00724 | Scaling type of the data element | ||
Description | This parameter scales the transferred value before it is transferred to the drive or after the value was read by the drive. This parameter sets the unit of the data item in the NC program independently of the drive. The scaling type influences the values of the following parameters:
| ||
Parameter | antr.fixed_stop.drive_ident[i].scaling_type | ||
Data type | STRING | ||
Data range | UNSCALED. | The value is not scaled, i.e. the value in the NC program directly corresponds to the value in the drive | |
LINEAR. | The value is weighted by a linear scaling factor (see P-AXIS-00728) | ||
TORQUE_DRIVE_SIDE. | The programmed value is a torque value related to the motor shaft and is scaled to the drive torque format with the parameters P-AXIS-00325, P-AXIS-00326 and P-AXIS-00392. The scaling factor does not change during gear change. The conversion factor is: | ||
Axis types | T, R | ||

Default value | UNSCALED | ||
drive types. | SERCOS, CANopen | ||
Remarks | Example: The torque limit in the SERCOS drive is specified in per mil of the maximum motor torque. However, the torque should be specified in percent in the NC program:
| ||
P-AXIS-00725 | Maximum permissible output value | |
Description | This parameter defines the maximum permissible output value. If the value specified in the configuration lists or in the NC program overshoots the set limit, it is automatically limited to the maximum value. No error message is then output. If P-AXIS-00725 is configured, P-AXIS-00726 must be less than this parameter, otherwise the warning P-ERR-70385 is output and the values are swapped. No value limit takes place by default. Irrespective of this parameter setting, a value range check always takes place with the specified data type P-AXIS-00722. If an overflow is detected, the controller outputs the error message P-ERR-70384. | |
Parameter | antr.fixed_stop.drive_ident[i].max_limit | |
Data type | REAL64 | |
Data range | Dependent on P-AXIS-00722 and P-AXIS-00724 | |
Axis types | T, R | |
Dimension | T: ---- | R: ---- |
Default value | 1.000000e+199 | |
Drive types | SERCOS, CANopen | |
Remarks | By default no limit is active; the limit is disabled at a value of 1.000000e+199. | |
P-AXIS-00726 | Minimum permissible output value | |
Description | This parameter defines the minimum permissible output value. If the value specified in the configuration lists or in the NC program undershoots the set limit, it is automatically limited to the minimum value. No error message is then output. If P-AXIS-00726 is configured, the parameter value must be greater than P-AXIS-00725, otherwise the warning P-ERR-70385 is output and the values are swapped. No value limit takes place by default. Irrespective of this parameter setting, a value range check always takes place with the specified data type P-AXIS-00722. If an overflow is detected, the controller outputs the error message P-ERR-70384. | |
Parameter | antr.fixed_stop.drive_ident[i].min_limit | |

Remarks | By default no limit is active; the limit is disabled at a value of 1.000000e+199. | |
P-AXIS-00727 | Writing/reading drive values by bit mask | |
Description | This parameter defines the bit mask to be used to read and write drive values bitwise. If the writing value (default value P-AXIS-00726 or the value when motion to the fixed stop is active P-AXIS-00729) is greater than zero, the bit mask is set; when the value is zero, the bits in the bit mask are deleted from the value transferred to the drive. When read, the value of a bit is returned if all the bits in the bit mask are set in the read drive object. Otherwise the return value is 0. This parameter is only used if the data type configured in P-AXIS-00722 has either the value 'BITARRAY_16' or 'BITARRAY_32'. The value of the bit mask must fit in the data type of the drive object P-AXIS-00722, otherwise the controller issues the error message P-ERR-70403. | |
Parameter | antr.fixed_stop.drive_ident[i].mask | |
Data type | STRING | |
Data range | Dependent on P-AXIS-00722: BITARRAY_16: Bit mask 16 Bit - 0 ... MAX(UNS16) BITARRAY_32: Bit mask 32 Bit - 0 ... MAX(UNS32) | |

P-AXIS-00728 | Scaling factor | |
Description | This parameter executes a scaling for reading and writing the drive object. This parameter only acts if the scaling type P-AXIS-00724 is set to 'LINEAR'. | |
Parameter | antr.fixed_stop.drive_ident[i].scaling_factor | |
Data type | REAL64 | |
Data range | Unequal to 0 | |
Axis types | T, R | |
Dimension | T: - | R: - |
Default value | 1.0 | |
drive types. | SERCOS, CANopen | |
Remarks | Example: The torque limit in the SERCOS drive is specified in per mil of the maximum motor torque. However, the torque should be specified in percent in the NC program: antr.fixed_stop.drive_ident[0].id TORQUE_LIMIT antr.fixed_stop.drive_ident[0].wr_ident S_0_0092 antr.fixed_stop.drive_ident[0].scaling_type LINEAR antr.fixed_stop.drive_ident[0].scaling_factor 10 | |
P-AXIS-00729 | Value of data element during Move to fixed stop | |
Description | This parameter specifies the value which the drive object must assume while moving to fixed stop. The specified value may also be scaled before output to the drive (see P-AXIS-00728). | |
Parameter | antr.fixed_stop.drive_ident[i].active_value | |
Data type | REAL64 | |
Data range | Unequal to 0 | |
Axis types | T, R | |
Dimension | T: - , dependent on P-AXIS-00728 | R: - , dependent on P-AXIS-00728 |
Default value | 0.0 | |
drive types. | SERCOS, CANopen | |
Remarks | Example: When moving to fixed stop, the torque should be limited to 10% of maximum torque:
| |
P-AXIS-00730 | Use of default value | |
Description | Normally, when moving to fixed stop is activated, the value of the drive object is read out before the object is changed by activating the function. After the function ends, the original settings are restored. If this parameter is set to 1, the start value P-AXIS-00723 is transferred to the drive instead of at the end of motion to fixed stop. The read process on activation can then be omitted. | |
Parameter | antr.fixed_stop.drive_ident[i].use_startup_value | |
Data type | BOOLEAN | |
Data range | 0 / 1 | |
Axis types | T, R | |
Dimension | T: - | R: - |
Default value | 0 | |
Drive types | SERCOS, CANopen | |
Remarks | If the object is communicated in the cyclic process data (P-AXIS-00720 = 'CYCLIC'), it is advisable to set this parameter to the value 1 since the start value in P-AXIS-00723 is already transferred cyclically to the drive. | |
P-AXIS-00731 | Name of the drive object to be read in the driver amplifier | |
Description | If the name of the drive object is different for read and write access, the name of the drive object to be read can also be specified here. If no value is specified here, the controller uses the name of the object in P-AXIS-00721 for read and write. | |
Parameter | antr.fixed_stop.drive_ident[i].rd_ident | |
Data type | STRING | |
Data range | Maximum of 29 characters | |
Axis types | T, R | |
Dimension | T: - | R: - |
Default value | * | |
Drive types | SERCOS, CANopen | |
Remarks | * Note: The default value of variables is a blank string. | |
P-AXIS-00746 | Use of default parameters for the drive type | |
Description | By default the drive objects for moving to fixed stop are preconfigured for each drive type when the controller starts and this overwrites any assignment made in the default axis parameter list. All parameters required to change the drive objects are affected by pre-initialisation, i.e. the parameters assigned in the structure antr.fixed_stop.drive_ident[i].*. However, it a parameterisation is used from the default list, this parameter can be set to the value 0. In this case, no default initialisation of the drive object takes place. | |
Parameter | antr.fixed_stop.drive_ident[i].default | |
Data type | BOOLEAN | |
Data range | 0 / 1 | |
Axis types | T, R | |
Dimension | T: - | R: - |
Default value | 1 | |
Drive types | SERCOS, CANopen | |
Remarks | This parameter is replaced by P-AXIS-00821(as of Build V3.1.3080.11). | |
P-AXIS-00762 | Quick stop after detecting the fixed stop. | |
Description | This parameter is used to force an immediate stop when the fixed stop is detected.
Normally, after the fixed stop is detected, the axes are stopped at the feedhold acceleration P-AXIS-00024 set for this axis. For time reasons, an immediate stop can be forced by the axis parameter "quick_stop_after_detection". The condition for this is that all axes involved in the approach movement detected a stop as, in this case, all moving axes are already at a standstill due to the stop. If other axes are also involved in the approach movement, the CNC therefore stops the axes at their normal deceleration rates P-AXIS-00024 despite the fact that the "quick_stop_after_detection" parameter is set. | |
Parameter | antr.fixed_stop.quick_stop_after_detection | |
Data type | BOOLEAN | |
Data range | 0 / 1 | |
Axis types | T, R | |
Dimension | T: ---- | R: ---- |
Default value | 0 | |
Drive types | SERCOS, CANopen | |
Remarks |
| |
P-AXIS-00763 | Error reaction for missing drive releases. | |
Description | If the drive releases are reset after the fixed stop is detected, the CNC generates the error message P-ERR-70546 and aborts the function "Move to fixed stop". This behaviour can be changed by the parameter "error_missing_drive_releases". | |
Parameter | antr.fixed_stop.error_missing_drive_releases | |
Data type | STRING | |
Data range | ERROR: Output of error message P-ERR-70546 and the Move to fixed stop function is aborted WARNING: Output of warning P-ERR-70546 and the Move to fixed stop function is aborted NONE: Abort the Move to fixed stop function | |
Axis types | T, R | |
Dimension | T: ---- | R: ---- |
Default value | ERROR | |
Drive types | SERCOS, CANopen | |
Remarks | Check the motion range of the axis before you set each release again. The stop obstacle must be removed. | |
