Turn ON the control power supply.
Make sure that the panel operator display is as shown below.
Check the input signal using the input signal monitor (Un005) from the panel operator. If the dis-
play is not the same as shown below, correct the input signal setting.
Note:
• If an absolute encoder is being used, turn ON the SEN signal. The servomotor will not turn
ON when only the servo ON signal (/S-ON) is input.
• When the SEN signal is checked using the monitor display, the top of the LED will light
because the SEN signal is high when ON.
• Input signals can be also checked using wiring check function of S.
