Note: The servomotor will not operate properly if the following signal lines are not wired correctly. Always
wire them correctly. Short the signal lines if they will be unused. The input signal selections (param-
eters Pn50A to Pn50D) can be used to eliminate the need for external short circuiting.

Note: IF an absolute encoder is being used, the servo will not turn ON when the servo ON signal (/S-ON) is

When the SEN signal is checked in monitor mode, the top of the LED will light because the SEN sig-
nal is high when ON.
