U.040 Outer Control Loop Feedback Source
This parameter
specifies what is
used as the outer
loop feedback signal.
Parameter Range: 0 = Terminal strip analog input scaled
(see Appendix F)
1 = Speed loop PI output (torque reference,
4095 = 150% torque)

U.048 Outer Control Loop Proportional Trim Enable
The feedback signal is fed through a lead/lag block which can be configured as a
lead/lag, lag/lead, or null (bypassed) function using parameter U.041 (Outer Control
Loop Lead/Lag Select). See Appendix G for the outer control loop block diagram.
U.041 Outer Control Loop Lead/Lag Select
This parameter
selects whether the
outer control loop
feedback lead/lag
block will operate as
a lead/lag, a lag/lead,
or a null function
(bypassed).
