(1) Secure the servomotor. Secure the servomotor to mounting holes to prevent it from moving during operation. Alternatively, install the servomotor on the machine and disconnect couplings and belts.
(2) Disconnect connector 1CN, then check the motor wiring in the power supply circuit. I/O signals (1CN) are not to be used so leave connector 1CN disconnected.
Note: When absolute encoder is used, connect the battery. Also, initialize the absolute encoder. See 3.8.5 Using an Absolute Encoder for details.
(3) Short the alarm signal circuit. Because connector 1CN is disconnected, the alarm signal prevents the power supply circuit from being turned ON. Therefore, temporarily short the alarm signal circuit.
(4) Turn the power ON. Turn the Servopack power ON. If the Servopack is turned ON normally, the LED on the Digital Operator lights up as shown in the figure. Power is not supplied to the servomotor because 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 incorrect. In this case, turn the power OFF, then correct 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 Operate the motor with the Digital Operator.
Check that the motor runs normally.
Refer to 4.2.2 Operating Using the Digital Operator.
(6) Connect signal lines. Connect connector 1CN as follows:
Turn the power OFF.
Retrun the alarm signal circuit shorted in the above stepto its original state.
