Chapter 7 Trial operation
Introduce the process and operation steps of the trial run and the functions that are convenient to use during
the trial run.
7.1 Commissioning process
7.1.1 Process of servo motor test run
The steps of the trial run are as follows.
Steps
Content
1
Settings and installation
Set the servo motor and servo drive according to the setting conditions. First
of all, confirm the action when there is no load. The servo motor is not
connected to the mechanical system here.
2
Wiring, connection
Connect to the servo drive.
Confirm the action of a single servo motor. Here, CN1 of servo drive is not
connected.
3
Confirmation before commissioning
4
Connect to the power
5
Setting of Absolute Value Encoder
This setting is made when only servo motors with absolute value encoders
are used.
7.2 Inspection and Precautions Before Commissioning
In order to carry out the trial run safely and correctly, please confirm the following items before the trial run.
The setting, wiring and connection of servo drive and servo motor have been carried out correctly.
The power supply voltage for servo drive is normal.
The fastening parts of the servo motor are not loose.
When using servo motor with oil seal, the oil seal is not damaged. And oil has been applied.
When using servo motors stored for a long time, the maintenance and inspection of servo motors have been
completed.
For the maintenance and inspection essentials of servo motor, please refer to the manual for using servo
motor.
Servo motors with brakes have previously released the brakes. When releasing the brake, the specified
voltage (DC24 V) must be applied to the brake. Examples of circuits for commissioning are as follows.
7.3 Commissioning of Servo Motor Unit
The JOG operation function is used during the trial operation of the servo motor unit.
JOG operation refers to the function of driving the servo motor at the preset JOG speed (rotation speed)
without connecting the upper device and confirming the action of the servo motor.

Notes
The over-travel prevention function is invalid during JOG operation. At the same time of operation, the operating
range of the machine must be considered.
7.3.1 Confirmation before execution
To run JOG, the following confirmation must be made in advance.
The write inhibit setting of the parameter is not set to "write inhibit".
