If the signal lines below are not wired correctly, the motor fails to rotate. Always wire
them correctly. (If signal lines are not to be used, short them as necessary.)
P-OT 1CN-42 Motor can rotate in forward direction when this input signal is at 0 V.
N-OT 1CN-43 Motor can reverse when this input signal is at 0 V.
S-ON 1CN-40 Servo is turned ON when this input signal is at 0 V. However, leave
the servo in OFF status.
(8) Turn servo (motor) ON.
Turn the servo ON as follows:
(1) Check that no reference has been input.
Speed/torque control mode :
V-REF (1CN-5) and T-REF (1CN-9) are at 0 V.
Position control mode:
PULS (1CN-7) and SIGN (1CN-11) are fixed.
(2) Turn the servo ON signal ON.
Set S-ON (1CN-40) to 0 V. If normal, the motor
is turned ON and the Digital Operator displays
the data as shown in the figure. If an alarm dis-
play appears, take appropriate action as de-
scribed in Appendix E List of Alarm Displays.
(9) Operate by reference input.
The operating procedure differs according to the Servopack control mode used.
Speed/Torque Control Mode
(This section describes the standard speed con-
trol setting.)
(1) Gradually increase the speed reference input
(V-REF, 1CN-5) voltage. The motor will rotate.
When a host controller such as a programmable controller performs position
control, it may be difficult to directly input the speed reference voltage. In this
case, constant voltage reference should be input once to ensure correct opera-
tion.
