Setting frequency and start/stop
status are moved to Local mode
when switching from Remote
mode to Local mode.
Motor runs continuously like an
example.
When switching from Local
mode to Remote mode, setting
frequency and start/stop status
are determined by Remote
mode status.
The example shows the motor
runs continuously because the
Remote mode is “run” status.
To prevent from moving the setting frequency and start/stop status of Remote mode to Local mode,
the
H is set to “ ”(Disabled). In this case, key is effective only while stopping.
