Description
Velocity and Acceleration values are scaled according to the EtherNet/IP Position Controller
Device standard. One “Profile Units” scaling value is defined, which affects both velocity and
acceleration.
For velocity values, Profile Units gives the number of actual position feedback counts (at 32
bits per revolution) per second equal to one velocity unit. For acceleration values, Profile Units
gives the number of actual position feedback counts (at 32 bits per revolution) per second^2
equal to one acceleration unit.
From Workbench, this scaling parameter is visible in the EtherNet/IP screen or as EIP.PRO-
FUNIT in the terminal. From EtherNet/IP, this value can be accessed at attribute 0x05 Profile
Units of the Position Controller object.
The default value is 2^16 = 65536, which provides 2^32 / 2^16 = 2^16 counts per second per rev-
olution. A value of 1 would provide 2^32 / 1 = 2^32 counts per second per revolution.
