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