Programming 5 - 27
Options - G, H, L, Q, or V
"Serial Communications"; Bypass with PI Control and serial communication for Setpoint input:
Hand mode speed command from Keypad/Operator.
Auto mode PI Setpoint input signal from serial communication.
Auto mode run/stop contact closure for Drive and Bypass applied to terminals TB1-3 and TB1-4.

"Serial Communications"; Bypass with PI Control and serial communication for run/stop control
and Setpoint input:
Hand mode speed command from Keypad/Operator.
Auto mode PI Setpoint input signal from serial communication.
Auto mode run/stop command for Drive from serial communication.
Auto mode run/stop contact closure for Bypass applied to terminals TB1-3 and TB1-4.

Parameter Setting
Result
b1-01 = 2: Serial Com
Speed command (Hand) and PI setpoint (Auto) source = Serial Communication
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 = 6E: Hand Mode Sel
S6 must be jumpered to S5
A terminal S6 input contact opening (H/O/A = Auto) puts the Drive in “Auto” mode
to allow b1-01 to determine the PI Setpoint source. A terminal S6 input contact
closure (H/O/A = Hand) puts the Drive in “Hand” mode to source the speed
command from the Keypad/Operator (overrides b1-01). 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

Parameter Setting
Result
b1-01 = 0: Operator
Speed command source = Keypad/Operator (U1-01)
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 = 2: 4-20 mA (default)
Terminal A2 is programmed for 4-20 mA (Note – Control PCB DIP switch S1-2
must also be ON)
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
