Yaskawa P7B Drive Bypass - Manual (Page 101)

Programming 5 - 7
" Options - S "Speed Pot."; Bypass with speed potentiometer for speed control:
Hand mode speed command from speed potentiometer.
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.
" Options - G, H, L, Q, or V "Serial Communications"; Bypass with serial communication for
control:
Hand mode speed command from Keypad/Operator.
Auto mode speed command 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.
" Options - G, H, L, Q, or V "Serial Communications"; Bypass with serial communication for
run/stop control and speed monitoring:
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 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 = 1: Terminals (default) Speed command source = Terminals
H3-13 = 1: Main Fref TA2 Main speed command source = Terminal A2 and the Aux speed command
source = Terminal A1
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 = 2: Aux Reference (default) Aux Terminal (A1) function is set to be a speed command input.
H1-03 = 3: Multi-Step Ref 1 (default) A terminal S5 input contact closure selects Aux Terminal (A1) as a preset
speed. This input contact is closed when H/O/A = Hand.

Result
b1-01 = 0: Operator Speed command source = Keypad/Operator (d1-01)
H1-03 = 6C: Com/Inv Sel 2 A terminal S5 input contact closure allows b1-01 to select d1-01 (keypad) as a
preset speed. An open contact selects serial com for speed command and run/
stop. This input contact is closed when H/O/A = Hand.

Parameter Setting
Result
b1-01 = 0: Operator Speed command source = Keypad/Operator (d1-01)
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 = 2: Aux Reference (default) Terminal A2 function is set to be a speed command input. This setting also
gives terminal A2 priority over d1-02 for “preset speed 2”, see Programming
Manual.
H1-02 = 3: Multi-Step Ref 1
S4 must be jumpered to SN A terminal S4 input contact closure selects A2 as “preset speed 2” speed input.
The S4 input is jumpered to SN, therefore it is always closed.
H1-03 = 6C: Com/Inv Sel 2 A terminal S5 input contact closure allows b1-01 to select d1-01 (keypad) as a
preset speed. An open contact selects serial com for the run/stop command
(the serial com speed command is overridden by the preset speed above). This
input contact is closed when H/O/A = Hand.
H1-04 = 4: Multi-Step Ref 2 (default)
S6 must be jumpered to S5 A terminal S6 input contact closure selects d1-04 (keypad) as a speed input.
When open, the speed command is determined by “preset speed 2”. This input
contact is closed when H/O/A = Hand.
