9.1.3 Operation by Forward/Reverse Input Terminals
 How to start or stop operation by an input signal to the control circuit terminal block?
 How to switch between forward and reverse rotation by turning on/off the input terminal on the
control circuit terminal block?
 To perform forward/reverse rotation and stop operation using the forward/reverse rotation
input terminals on the control circuit terminal block, set the "RUN command input source
selection [A002]
*1
" to "Control terminal (01)" and assign "Forward rotation [FW]" and "Reverse
rotation [RV]" to "Input terminal function [C001] to [C007]".
 In the factory default state, "Forward rotation [FW]" is assigned to terminal 1 and "Reverse
rotation [RV]" to terminal 2.
The terminal assignments can be changed by configuring "Input terminal function [C001] to [C007]".
 The a/b (NO/NC) contact state can be changed for each terminal by configuring the "Input
terminal active state [C011] to [C017]".
 If the [FW] and [RV] terminals are both on at the same time, a stop command is issued. The
relationship between the [FW]/[RV] terminal input states and the RUN commands is shown in
the following table.

 For the inverter to start operation, a frequency command is required in addition to a RUN
command.

reserved variables <FW>/<RV> of the program operation function EzSQ are enabled and can
also respond to commands.
