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, REMLOC key is effective only while stopping.
