5 Drive Programming User Variables
5 - 4
Drive Programming User’s Manual (I580-E2)
• The internal user contact (word access) UBw is a function to use the internal user contacts UB(0) to
UB(7) as a word-size variable.
• The internal user contacts UB(0) to UB(7) are set in the lower byte. For the upper byte data, zero is
read out. If any data is written to the upper byte, the data is ignored.
When the Drive Programming program is stopped, the data of internal user contacts before the
program stop is retained. When the program execution is started again, the process begins with
the retained data.
