1090 HEIDENHAIN Technical Manual MANUALplus 620
TNCopt Commissioning the digital control loops should be performed with the TNCopt
commissioning and optimization software. Refer to the detailed information in
the TNCopt User's Manual. It is available as a PDF document via the HESIS-
Web Including Filebase on the Internet
(http://hesis.heidenhain.de) and is also provided as online help with TNCopt.
Current controller The current controller must be adjusted with TNCopt. The speed and position
control loops are opened when you adjust the current controller. You must
therefore activate a special PLC commissioning program:
Open the machine configuration.
Enter the path to the PLC commissioning program in the MP_pwmPgm
parameter of the System/Path/CfgPlcPath configuration object.
Save the changes to the machine configuration.
Restart the MANUALplus 620.
It suffices to program an EM (end module) in the PLC commissioning program.
The drive must be enabled externally and the MANUALplus 620 needs the
"ready" signal.
Adjusting the current controller:
Do not acknowledge the Power Interrupted message. In the Organization
mode of operation, use the MOD key to enter the code number 94655. The
MANUALplus 620 will start the Current Controller and Field Angle
Adjustment special mode of operation in the background.
Switch to the Machine mode of operation.
Press the CE key, wait until the PLC program has been compiled and switch
the "control voltage" on.
A selection window will be displayed on the screen. Select a combination of
axis and parameter set for the adjustment and press the Current Control
soft key.
Open TNCopt and connect to the MANUALplus 620.
Load the machine parameters from the control.
Adjust the current controller as described in the TNCopt User's Manual.
When the adjustment has been completed, select the next axis in the
selection dialog etc.
On completion of the adjustment, transfer the current controller parameters
determined by TNCopt to the MANUALplus 620.
If you use the CC 61xx or UEC 11x controller unit, always adjust all control
loops (axes and spindle) without overshoot.
