(4) Turn the power ON.
Turn the Servopack power ON. If the Servo-
pack is turned ON normally, the LED on the
Digital Operator lights up as shown in the fig-
ure.
Power is not supplied to the servomotor be-
cause the servo is OFF.
If an alarm display appears on the LED as
shown in the figure above, the power supply
circuit, motor wiring or encoder wiring is incor-
rect. In this case, turn the power OFF, then cor-
rect the problem.
Note: When absolute encoder is used, perform
the following procedures after turning ON
the power.
Set the bit E of Cn−01 to 1.
Set the number of encoder pulses (Cn−11)
to 1024.
Set the dividing ratio of encoder pulses
(Cn−0A) to 1024 or below.
Turn OFF the power once. Then turn ON
the power again after checking if the displays
of digital operator extinguish.
(5) Operate using the Digital Operator
