YASKAWA E7LVD002 Technical Manual page 105

If you want the Drive to follow the speed command set by the digital operator: Use the HAND mode by pressing the
HAND key of the HAND/OFF/AUTO selector. The speed command can then be entered into the U1-01 monitor parameter in
the "-DRIVE-" Menu.
If you want the Drive to follow an AUTO analog speed command: Connect a 0 – 10 VDC or a 4 – 20 mA speed command
signal to terminals TB3-3 (positive) and TB3-1 (common). Select the AUTO position of the Hand/Off/Auto selector.
If you want the Drive to receive the speed command from serial communication: Set the parameters indicated in Table 5.2
for the desired serial communication option. Connect the RS-485/422 serial communications cable to terminals TB4-3 (R+),
TB4-4 (R-), TB4-1 (S+), and TB4-2 (S-) on the E7L PCB A2. The HAND/OFF/AUTO selector must be in the AUTO
position.
b1-02 Run Source
Setting
0 Operator
1 Terminals (factory default)
2 Serial Com
3 Option PCB
To successfully operate the Drive or Bypass and motor remotely, an external run command must be received by the Drive and
Bypass unit. Parameter b1-02 specifies from where the run command for the Drive will be accepted.
This parameter is by default set to "1: Terminals." This setting is required by the Bypass logic circuit.
To issue a run command from the control panel: Press the HAND key of the Hand/Off/Auto selector.
To issue a run command from a remote source, such as a BAS: The Hand/Off/Auto selector must be in the AUTO position.
A contact closure between terminals TB1-2 and TB1-9 will control the Drive or Bypass start and stop operation.
To issue a run command via serial communication: Set the parameters indicated in Table 5.2 for the desired serial
communication option. Connect the RS-485/422 serial communication cable to TB4-3 (R+), TB4-4 (R-), TB4-1 (S+), and
TB4-2 (S-) on the E7L PCB A2.
b1-03 Stopping Method
There are four methods of stopping the Drive when the Run command is removed.
Setting
0 Ramp to Stop (factory default)
1 Coast to Stop
2 DC Injection to Stop
3 Coast w/Timer
"0:Ramp to stop": When the Run command is removed, the Drive will decelerate the motor to 0 rpm. The rate of deceleration
is determined by the active deceleration time. The factory default Decel Time is in parameter C1-02.
