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 "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
"Operating 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 HEIDENHAIN customer service.

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 the section "EMERGENCY STOP routine".
– Test the EMERGENCY STOP-circuit by pressing the EMERGENCY STOP keys and by traversing
past the EMERGENCY STOP limit switches.
