Description
Position values are scaled according to the Ethernet/IP Position Controller Device standard. One “Position
Units” scaling value is defined, which gives the number of actual position feedback counts (at 32 bits per
revolution) equal to one position unit.
From Workbench, this scaling parameter is visible in the Ethernet/IP screen or as EIP.POSUNIT in the ter-
minal. From Ethernet/IP, this value can be accessed at attribute 0x04 Position Units of the Position Con-
troller object.
The default value is 2^16 = 65536, which provides 2^32 / 2^16 = 2^16 counts per revolution. A value of 1
would provide 2^32 / 1 = 2^32 counts per revolution.
