IP 266
For testing, a set of machine data and a traversing program are stored on
EEPROM. Since this data does not necessarily coincide with your hardware, you
may find that errors will be reported. Change the machine data as indicated by
the error messages. These messages, and the changes they indicate, will apply
primarily to the encoder type, the polarity and the encoder resolution.
C A U T I O N :
The IP 266 outputs the enable signal (FUM) directly when it detects data whose
logic and signal level are correct. If a positioning operation was triggered, it will
be started immediately!
Correct the machine data as indicated by the error messages.
Generate a traversing program for modes 8 and 9 and transfer it to the IP 266.
Testing the axis
Select the COM 266 test mode.
Start mode 4 (follow-up mode)
The following is displayed in the screen form's output fields:
Switch on the power section
The axis must remain at zero speed and its drift must be barely perceptible. If
this is not the case, you must repeat the fine adjustment for 0 volts on the
drive.
Stop mode 4 and check the return data.
