Parameter Setting
b1-01 = 0: Operator
b5-01 = 1: Enable
H1-03 = 6C: Com/Inv Sel 2
H1-04 = 19: Disable
Jumpers required:
TB5-5 to TB1-12 and TB1-13 to
TB5-2
H3-08 = 0: 0-10 VDC
H3-09 = B: PI Feedback
H5-02 = Baud Rate
H5-07 = RTS Control
H5-08 = Protocol Selection
Drive Operational Result
Speed command source = Keypad/Operator (U1-01)
Enable PI mode of operation
A Drive terminal S5 input contact opening (H/O/A = Auto) selects serial com for
both the run/stop command and speed command. A Drive terminal S5 input contact
closure (H/O/A = Hand) allows b1-01 to select Keypad/Operator as the speed
command source. This input contact is closed when H/O/A = Hand.
A Drive terminal S6 input contact closure disables PI mode.
Drive Terminal A2 is programmed for 0-10 VDC (Note - Control PCB DIP switch
S1-2 must also be OFF)
Drive Terminal A2 function is set to provide PI feedback for closed loop control
Each protocol requires the baud rate indicated in Table 5.2
Each protocol requires the Request to Send control indicated in Table 5.2
Drive communicates via protocol selected. 0: Modbus, 1: N2 or 2: FLN
