3-5 Test Run Procedure
3
If no problem is found during no-load run, connect the mechanical system and run the inverter with load
via the Digital Operator.
Mechanical system connection
Make sure that the motor has stopped completely before connecting the mechanical system.
Then, connect the mechanical system with the motor shaft securely to prevent the screws from
loosening.
Operation via digital operator
In case of abnormal inverter run, be prepared to press the STOP/RESET key on the Digital
Operator.
In the same way as you did during no-load run, stop the machine via the Digital Operator.
RUN mode checks
Start with a low speed and, while checking that the machine moves smoothly in a correct direction,
increase the Output Frequency Setting/Monitor (F001) value.
Check that there is no mechanical vibration and noise by varying the Output Frequency
Setting/Monitor (F001) and RUN Direction Selection (F004) settings.
Also, check, using the Output Current Monitor (d002) and DC Voltage Monitor (d102), that the
current/voltage is still far from the value at which a trip error occurs.
To operate the inverter with only basic parameters, refer to Section 5 Basic Settings.
To use applied functions such as the sensorless vector control, sensor vector control, speed control,
torque control, and position control modes, in addition to Section 5 Basic Settings. refer to
Section 6
Vector Control.
