Yaskawa E7B Drive Bypass - Manual (Page 122)

Programming 5 - 28
Options - J and S "Serial Communications" and "Speed Pot."; Bypass with PI Control and serial communication for run/stop
control and Setpoint input, with hand mode speed potentiometer:
Hand mode speed command from speed potentiometer.
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.
Options - L "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
Drive Operational Result
b1-01 = 1: Terminals (default) Speed command (Hand) and PI setpoint (Auto) source = Terminals
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 = 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
H5-08 = 0: Modbus, 1: N2 or 2: FLN Drive communicates via protocol selected
