Discussion of Table 5.2 Option-Dependent Bypass Parameter Settings:
Drive Parameter Settings for Various Combinations of Bypass and Options
Notes:
See Appendix D, Communications, for additional information on serial communication.
Hand mode run/stop for Drive and Bypass is always via the front control panel HAND/OFF/AUTO switch.
The HAND/OFF/AUTO switch must be in AUTO position if serial communication is to be used to control the Drive.
For "monitoring only" of Drive parameters and operation, via serial communication, the user needs only to set-up the
H5-0X "Serial Com Setup" parameters. All other parameters may remain as they were factory programmed for the
Bypass unit and options.
Option L, LonWorks serial communication always requires DIP switch S1-1 (terminating resistor) to be ON.
" Options - None; Bypass with no options:
Hand mode speed command from Keypad/Operator.
Auto mode speed command input signal, 4-20 mA applied to Drive terminal A2.
Auto mode run/stop contact closure for Drive and Bypass applied to terminals TB1-3 and TB1-4.
" Options - None; Bypass with no options:
Hand mode speed command from Keypad/Operator.
Auto mode speed command input signal, 0-10 VDC applied to Drive terminal A2.
Auto mode run/stop contact closure for Drive and Bypass applied to terminals TB1-3 and TB1-4.

Parameter Setting
Result
b1-01 = 1: Terminals (default) Speed command source = Terminals
H3-13 = 1: Main Fref TA2 Specific speed command source = Terminal A2
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)
H3-02 = 0.0 Terminal A1 gain = 0.0 (To insure no stray signal level at this unused terminal)
H3-09 = 0: Frequency Bias Terminal A2 function is set to “bias” the terminal A1 input. Terminal A1 is not
used, therefore the A2 “bias” signal becomes the speed command.
H1-03 = 3: Multi-Step Ref 1
(default) A terminal S5 input contact closure selects d1-02 (keypad) as a preset speed. This
input contact is closed when H/O/A = Hand.
