Trial Operation

After the wiring is complete and the parameter settings have been made, conduct a trial
operation. First, in system check mode, check the motor's rotation direction without con-
necting a load (i.e., without connecting the mechanical system), and check to be sure
that the I/O signals are correctly wired. Then, connect the mechanical system, auto-tune
the system, and confirm that the correct operation pattern is performed. If an error
occurs during trial operation, refer to Chapter 4 Application and apply the appropriate
measures.

3-8-1 Trial Operation Procedure

Preparations
j Turning OFF the Power Supply
The power supply must be turned OFF and back ON in order for some of the parameter settings to go
into effect, so always turn OFF the power supply before starting.
j Leaving the Motor With No Load Connected
Do not connect a load to the motor shaft during trial operation in case the motor runs out of control.
j Preparing to Stop the Motor
Make sure that the power switch can be turned OFF or the RUN command can be used to stop the motor
immediately in case of trouble.
Actual Trial Operation
(1) Powering Up
With the RUN command OFF, apply an AC voltage.
After internal initialization, the mode will be the Monitor Mode.
Monitor display example:
Set the speed loop proportional gain (AJ2.) to approximately 1.0. (Match the gain with no load.)
1. Confirm the initial display (Monitor Mode) shown above.
2. Press the Mode Key twice to enter the Adjustment Parameters Edit Mode.
3. Press the Increment Key to display the contents of AJ2. (speed loop proportional gain).
4. Press the Shift Key and Data Key to enable the data to be changed. (The digit that can be changed
will flash.)
5. Press the Shift Key, Increment Key, or Decrement Key as required to change the setting to 1.0.
6. Press the Data Key to end the data change operation.
