Programming 5 - 28
Options - G, H, L, Q, or V and S "Serial Communications" and "Speed Pot."; Bypass with PI Control and serial communica-
tion for run/stop control and Setpoint input, with hand mode speed potentiometer:
Hand mode speed command from speed potentiometer.

Parameter Setting
Result
b1-01 = 1: Terminals (default) Speed command (Hand) and PI setpoint (Auto) source = Terminals
b5-01 = 1: Enable Enable PI mode of operation
H1-03 = 19: PI Disable A terminal S5 input contact closure disables PI mode. This input contact is closed
when H/O/A = Hand.
H1-04 = 6C: Com/Inv Sel 2 S6 must
be jumpered to S5 A terminal S6 input contact opening (H/O/A = Auto) selects serial com for both the
run/stop command and speed command. A terminal S6 input contact closure
(H/O/A = Hand) allows b1-01 to select Keypad/Operator as the speed command
source. This input is jumpered to S5, therefore the contact is closed when
H/O/A = Hand.
H3-08 = 0: 0-10 VDC Terminal A2 is programmed for 0-10 VDC (Note – Control PCB DIP switch S1-2
must also be OFF)
H3-09 = B: PI Feedback Terminal A2 function is set to provide PI feedback for closed loop control
H3-13 = 1: Main Fref TA2 Terminal A2 (the feedback terminal) serves as the main input
