TNC 360 16 Commissioning and Start-up Procedure 4-231
16.3 Commissioning the control
The machine must be prepared in accordance with Section 16.2 before the machine parameters for
commissioning can be optimized.
Before connecting the control, the NC and PLC supply voltages and the ground connections should
be tested once more (see Chapter "Mounting and electrical installation ").
16.3.1 Entry of the provisional and pre-defined machine parameters
After switching on the machine for the first time, the control will first of all display the message
"Operation parameters erased", which means that the machine parameters still have to be entered
(see "Machine parameters").
Most machine parameters can be pre-defined and entered according to the machine parameter list
and the functional descriptions. The parameters which affect the control loop must be assigned
provisional values (see Section 16.3.6).
In order to avoid lengthy delays on restarting during the commissioning of the control, the memory
test can be suppressed by MP7690 (see Section "Display and operation").
16.3.2 Entry of the PLC program
A complete PLC program for all machine functions must be created for commissioning and stored
either in EPROM or RAM (see "PLC programming").
Machine parameter MP4010 (see Section "Display and operation") selects whether the processing
uses a PLC program from EPROM or from RAM.
The PLC program in RAM is used for commissioning purposes. It only makes sense to create an
EPROM when all functions are operating without error. In case of doubt, please contact your
HEIDENHAIN customer service agency
16.3.3 Testing the EMERGENCY STOP routine
Since the EMERGENCY STOP circuit is very important for the machine it is vital that it is tested!
– Test the Function "Control operational" according to Section "EMERGENCY STOP routine".
– Test the EMERGENCY STOP circuit by pressing the EMERGENCY STOP keys and by traversing
past the EMERGENCY STOP limit switches.
