Use the integrated oscilloscope to adjust the current controller. The speed and
position control loops are open when you adjust the current controller. You
must therefore activate a special PLC commissioning program:
7 7 7 7
Enter the name of this PLC program in the OEM.SYS file with the instruction
PLCPWM=.
It suffices to program an EM (end module).
The drive must be enabled externally and the TNC needs the "ready" signal.
As soon as the PLC program defined with PLCPWM= is active, you can use
Module 9168 to interrogate the commissioning status.
