Trial Operation
5.2.6 No-load Operation
5 - 12
D
All set constants (motor constants) will be initialized if a fault occurs. Reset the constants from the be-
ginning when before starting autotuning again.
J
Unsuccessful Autotuning
When autotuning has not been executed correctly, “Tune Aborted” will be displayed. If this happens, input
the motor constants (E1-04 to E2-09) obtained from Steinbetz’s constant. For input details, refer to Techni-
cal Document EZZ0007798.
5.2.6 No-load Operation
The section describes trial operation in which the motor is operated from the Digital Operator with the motor
in the no-load state (with the motor not connected to the mechanical system).
J
Setting the Frequency Reference
Set the frequency reference on the frequency reference monitor in the operation mode.
The following is an operation example with the frequency reference set to 10 Hz.

Operation Using the Digital Operator
D
Press the RUN Key. The motor will start to rotate. (forward rotation)
D
Press the FWD/REV Key. The motor will rotate in the reverse direction.
D
Press the Stop Key. The motor will stop. (The RUN Key indicator will keep blinking until the motor
stops.)
D
The frequency reference can be changed, even during operation. When this is done, the frequency refer-
ence is changed as soon as the DATA/ENTER Key is pressed to input the set values.
D
If the Jog Key is pressed when the Inverter is stopped, it will rotate by the jog frequency (Factory setting:
6.0 Hz) only while the Key is being pressed.
J
Checking the Operating Status
D
After changing the frequency reference or the rotation direction, check that there is no oscillation or ab-
normal sound from the motor.
D
Check that no faults have occurred in the Inverter during operation.
5.2.7 Loaded Operation
After checking the operation under the no-load conditions, connect the load mechanical system and perform
trial operation with an actual load.
J
Connecting the Load System
D
After confirming that the motor has stopped completely, connect the mechanical system.
