Modify the plc_attr.cfg file:
The current plc_attr.cfg file is located in the control in the directory
PLC:\config\lathe\manplus\plc_attr.cfg. You can use TNCremoNT to copy
the file from the control to the PLC project, or you can use PLCdesignNT to
modify the previous file in the PLC project.
For all 43 timers, in the plc_attr.cfg file delete the line event:=NOTHING, in
every CfgAttrEntity with name:="CfgPlcTimer-...":
CfgAttrEntity (
name:="CfgPlcTimer-TR_Cax_Aus_Entprellen",
event:=NOTHING, ; This line must be deleted
protection:=LEVEL1

Checking the
direction of spindle
rotation
The evaluation of the MP_signCorrNominalVal parameter was revised for
spindles. The MANUALplus 620 therefore adjusts the value of the
MP_signCorrActualVal parameter automatically when the NC software is
updated. After the value has been adjusted, the MANUALplus 620 displays
the message Check the parameter for the direction of spindle rotation!.
Check the direction of spindle rotation. Proceed as follows:
Check whether the spindle turns with M3 and M19 in the correct direction.
If required, use the parameters MP_signCorrNominalVal (400002) and
MP_signCorrActualVal (400001) to define the direction of rotation
correctly, See "Defining the traverse direction" on page 663.
Operation of a
C axis with
separate drive
Please note that, if the same position encoder is used for the main spindle
and the C axis, the operation of a separately driven C axis along with the
use of a CC 61xx is not possible until the beginning of 2012. Contact
HEIDENHAIN if you need this feature before the above mentioned date.
