Inverter operation control by EzSQ
 When setting the inverter run/stop command, output frequency, and acceleration/deceleration
time using the reserved variable of EzSQ function, set the respective command of RUN
command input source, frequency input source and acceleration/deceleration time input
source to "EzSQ".
However, if you want to operate EzSQ program but use Modbus communication as the
frequency input source, set the input source as desired. (EzSQ operation is available without
setting the input source to "EzSQ".)
