Miscellaneous Parameters

Direction of the reference point approach
To enable exact reproducibility, the reference point must always be approached
from the same direction. The direction is selected by specifying "forw" for
forward or "rev" for reverse.
Note:
Specification of the direction is crucial to the reproducibility of the reference
point (see Section 5.3.5).
PLC BCD-coded
You must enter "yes" in this field when you want to enter the positioning
specification data in BCD format. Entries in BCD code must be in the range
±9 999.999 mm.
Actual value, distance to go and following error, when monitored, are also out-
put in BCD code.
Polarity of the hardware limit switches
The hardware switches and the IP 266 "External Stop" may be designed as NO or
NC contacts. You must enter the identifier for NO or NC in the machine data.
Enter "pos" to identify the switches as NO contact.
Enter "neg" to identify the switches as NC contacts.
IP STOP if CPU STOP
If you enter "YES", the operation in progress when the CPU stops is aborted.
