YASKAWA CIMR-F7Z44P0 User Manual page 80

To successfully operate the Drive remotely, an external run command must be received by the Drive. Parameter b1-02
specifies from where the run command will be accepted.
Although the Run Source and the Reference Source (b1-01) are normally taken from the same source (e.g. digital
operator, terminals or serial communication), this is not always the case.
To issue a run command from the digital operator: Set b1-02= "0: Operator", and use the HAND and OFF buttons to start
and stop the Drive.
To issue the run command from the terminals: Set b1-02= "1: Terminals", and select between 2-wire and 3-wire control
operation by doing the following:
2-Wire Control The factory default setting is for 2-wire operation. In the 2-wire configuration a closure between S1 and SN
will be interpreted as a Forward Run command by the Drive. A closure between S2 and SN will be interpreted as a Reverse
Run command. If both S1 and S2 are closed, the Drive will stop (decelerate to zero speed) and the digital operator will display
an EF (external fault) alarm (Flashing).
3-Wire Control When any of the multi-function digital input parameters, H1-01 through H1-05, is set to 0, terminals S1 and
S2 become Run and Stop, respectively. The multi-function digital input that was set to 0 will function as a Forward/Reverse
input for the Drive. When the Forward/Reverse input is open the Drive will run in the Forward direction and when the input is
closed, the Drive will run in the Reverse direction.
In 3-wire operation a momentary closure (> 50mS) of S1 will cause the Drive to run provided that S2 is held closed. The Drive
will stop anytime the S2-SN connection is broken. If the 3-wire configuration is implemented via a 3-wire Initialization
(A1-03= "3330: 3-Wire Initial"), then terminal S3 becomes the Forward/Reverse input.
To issue a run command via serial communication: Set b1-02= "2: Serial Com" and connect the RS-485/422 serial commu-
nication cable to R+, R-, S+, and S- on the removable terminal block. Be sure to use this setting when using the L
option card.
To issue the Run command via a network communication card other than L
Option PCB", and plug a option board into the 2CN port on the Control PCB. Consult the manual supplied with the option
board for instructions on integrating the Drive into your L
