3 Operation and Test Run
 Stopping the motor
After rotating the motor with no-load in the forward or reverse direction via the Digital Operator,
press the
Load Run
If no problem is found during a no-load run, connect the mechanical system and run the inverter with a
load via the Digital Operator.
 Connecting the mechanical system
Before connecting the mechanical system, make sure that the motor has stopped completely.
Then, connect the mechanical system to the motor securely to prevent the mounting screws from
loosening.
 Operation via Digital Operator
In case of unexpected abnormal inverter operation, be prepared to press the
Operator.
In the same way as during a no-load run, operate the machine at low speed and then decelerate to
stop via the Digital Operator.
 RUN mode checks
After checking that the machine moves in the correct direction and smoothly at low speed, set a
larger output frequency.
Check that there is no mechanical vibration and noise by altering the output frequency setting and
forward rotation (2: Touch panel operation (forward)) and reverse rotation (3: Touch panel operation
(reverse)) at 1st RUN Command Selection (F02).
Also, check the current, load rate and voltage values at Output current effective value (monitor
mode: 3_02), Motor Electronic Thermal (monitor mode: 5_62) and Main Circuit DC Voltage (moni-
tor mode: 5_01).
Check that the output current is up to 150% of the motor rated current.
Also, check that the electronic thermal load rate is sufficiently low to reach 100%.
Check that the DC voltage for 200-V class and for 400-V class is sufficiently low to reach 390 VDC
and 780 VDC, respectively.
Operation
To operate the inverter by only basic parameters, refer to Section 5 Basic Settings on page 5-1.
To use applied functions such as sensorless vector control, V/f control with speed feedback, torque
control, and simple position control, in addition to Section 5 Basic Settings on page 5-1, refer to
Section 6 Vector Control and Applied Functions on page 6-1.
