Delta RMC151 - Manual (Page 723)

8 Command Reference
Use this command when you want to give an Open Loop Control Output to the axis. Open
Loop is good for making the axis move when you don't care about going exactly at a
certain speed or reaching an exact position.
Target Generator State Bits
The Target Generator bits in the Status Bits register indicate which portion of the move
the axis is currently in. These bits are useful when programming complex motion
sequences.
Target Generator Done bit
This bit indicates the move is complete, which occurs when the Control Output has
reached the Requested Output.
Target Generator State A and B bits
B A Description
0 0 Constant Control Output at 0 volts
0 1 Ramping Control Output away from 0 volts
1 0 Constant Control Output at a non-zero voltage
1 1 Ramping Control Output toward 0 volts
