Yaskawa E7 Drive User Manual - Manual (Page 78)

Programming 5 - 4
b1 Sequence
The Sequence Group contains parameters associated with starting and stopping the Drive. Parameters involving the Run
Command, Speed Reference location, Stopping Method and Hand/Auto changeover are located in this group.
b1-01 Reference (Speed Command) Source Selection
In order to run the Drive and motor, the Drive must receive a Run command and a speed command. Parameter b1-01 specifies
from where the speed command is received when in the “Auto mode. Switching into the “Auto” mode can be done by pressing
the AUTO button on the digital operator while the Drive is stopped.
If you want the Drive to follow the speed command set by the digital operator: Use the “Hand” mode by pressing the hand
key or set b1-01= “0: Operator”. 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: Set b1-01= “1: Terminals”, and connect a 0 – 10 Vdc
speed command signal between terminals A1 and AC or a 4 – 20 mA speed command signal to terminals A2 and AC.
If you want the Drive to receive the speed command from serial communication: Set b1-01= “2: Serial Com”, and connect
the RS-485/422 serial communications cable to terminals R+, R-, S+, and S- on the control I/O terminal block. Be sure to use
this setting when using the L
ON W ORKS® option card.
If you want to use a network communication card other than L ON W ORKS® to input a speed command: Set b1-01= “3: Option
PCB”, and plug the network option board into the 2CN port on the Drive Control PCB. Consult the manual supplied with the
option board for instructions on integrating the Drive into the network.
b1-02 Run Source
Setting Description
0 Operator - Digital Preset Speed d1-01
1 Terminals - Analog Input Terminal A1 (or Terminal A2, see Parameter H3-13)
2 Serial Com - RS-485 Terminals R+, R-, S+ and S-
3 Option PCB - Option Board connected at 2CN
IMPORTANT
If a Run command is input to the Drive but no corresponding speed command is input, the Run indicator on
the digital operator will turn on and the STOP indicator on the digital operator will blink.
IMPORTANT
If b1-01= “3: Option PCB” but a network card is not installed in 2CN, an OPE05 Operator Programming
Error will be displayed on the digital operator and the Drive will not run.
Setting Description
0 Operator
1 Terminals (factory default)
2 Serial Com
