• Make sure there are no issues related to safety around the motor and machinery.
• Ensure that all emergency stop circuits and machine safety mechanisms are functioning correctly.
Checklist before Operation
Before operation check the following items:
• Is the motor rotating in the forward direction?
• Is the motor rotating smoothly (no abnormal sounds or abnormal vibrations)?
• Is the motor accelerating and decelerating smoothly?

Perform a No-Load Test Run
This section explains how to perform a no-load test run.
1.
Set b1-01 = 0 [Frequency Reference Selection 1 = Keypad] or b1-02 = 0 [Run Command Selection 1 =
Keypad].

LED illuminates, and the motor runs at 6.00 Hz in the forward direction.
5.
Make sure that the motor is rotating in the correct direction and that the drive does not show a fault.
If the drive detects a fault, remove the cause.

Load Shaft)
6.
Push
to increase the frequency reference.
Change the setting value in increments of 10 Hz if necessary and examine the response.
7.
Each time you increase the setting value, use U1-03 [Output Current] to check the drive output current.
When the output current of the drive is not more than the motor rated current, the status is correct.
Example: 6 Hz -> 20 Hz -> 30 Hz -> 40 Hz -> 50 Hz -> 60 Hz
8.
Make sure that the motor rotates correctly, then push
will flash. When the motor stops, the LED will go out.
Change settings as needed according to how b1-01 and b1-02 have assigned the Run command source and
frequency reference.

Crane Application Setup Procedure
■
External Interlock
In applications where the system will be negatively impacted if the drive goes down, always create an interlock
between fault relay output and the Ready signal of a multi-function digital output.
Drive Ready
MFDO: The Drive Ready (READY) signal turns on when the drive is ready and running. The READY signal will
be switched OFF in the following situations if the drive cannot be operated, even when no fault signal is detected
or output, and even when the Run command is entered.
• The drive is de-energized
• During a fault
• There is problem with the control power supply
• There is a parameter setting error that will not let the drive run, although a Run command is entered
