46
Cn-24,Cn-25 Electronic gear ratio (see page 81)
Cn-02 bit 0 Reverse rotation mode (see page 54)
If an alarm occurs or the motor fails to rotate during the above operation, connector 1CN
wiring is incorrect or the parameter settings do not match the host controller specifica-
tions.
In this case, check the wiring and review the parameter settings, then repeat step 1.
Refer to Appendix D List of Alarm Displays and Appendix C List of Parameters.
This is all that is required to complete step 1 (conducting a test run for motor without load).
Whenever possible, perform tuning associated with the host controller and other neces-
sary adjustments in step 1 (before installing the motor on the machine).
2.4.3 Step 2: Conducting a Test Run with the Motor Connected to
the Machine
After step 1 is complete, proceed to step 2 in which a test run is conducted with the motor
connected to the machine. The purpose of step 2 is to adjust the SERVOPACK according to
the machine characteristics.
Conduct a test run according to the procedure described below.
Purposes: S Autotuning
S Speed adjustment
SGDB
SERVOPACK Servomotor
Connect to the machine.
NOTE Before proceeding to step 2, repeat step 1 (conducting a test run for the motor without load)
until you are fully satisfied that the test has been completed successfully. Operation faults that
arise after the motor is connected to the machine not only damage the machine but may also
cause an accident resulting in injury or death. Therefore, all items including parameters set-
ting and wiring should be tested as conclusively as possible before step 1 is complete.
1. Check that power is OFF.
Turn the SERVOPACK power OFF.
