Chapter 6 Operation

6.6 Motor Operation
Both “Run command” and “frequency command” is necessary to run the motor. Motor does not run if one
of each is missing. For example, motor will not run when a run command is given, but a frequency
command is 0Hz. Additionally, the motor will not run if a FRS (free run stop) signal (and the like) is being
given.
NE-S1 series inverter has following way to set the run command and frequency command. (This is an
example of sink logic and uses internal control power supply.)
(A) Driving with the standard panel
RUN/STOP/RESET key on the standard operation panel is effective regardless of the setting of the
driving order method(A002). Thus, following driving method (1) to (3) is possible without an option if it is
factory default setting.
(1)Method to perform driving in RUN/STOP/RESET key and perform frequency setting in Multispeed
select
This is the operation method using Run command is given by "RUN/STOP/RESET key" & Frequency
setting is given by Fixed value such as 20/40/60Hz, Accel&Decel time is 10 seconds. If you don't need
to change such as Accel&Decel time, optional Operator is not required.) To set the Freq. setting, use
the Multi-speed frequency setting (1=60Hz),(2=40Hz),(3=20Hz).
