8. Trial Operation

8.1 Preparations for Trail Operation
The procedure for trial operation is given below.

 

8.2 Inspections and Confirmations
To ensure safe and correct trial operation, check the following items before you start trial operation.
 Make sure that the Drive and Motor are installed, wired, and connected correctly.
 Make sure that the correct power supply voltage is supplied to the Drive.
 Make sure that there are no loose parts in the Motor mounting.
 If you are using a Motor with an Oil Seal, make sure that the oil seal is not damaged. Also make sure that oil has been applied.
 If you are performing trial operation on a Motor that has been stored for a long period of time, make sure that all Motor inspection and maintenance procedures have been completed.
 If you are using a Motor with a Holding Brake, make sure that the brake is released in advance. To release the brake, you must apply the specified voltage of 24 VDC to the brake.
A circuit example for trial operation is provided below.

8.3 Motor Operation without a Load
You use jogging for trial operation of the Motor without a load.
Jogging is used to check the operation of the Motor without connecting the Drive to the host controller. The Motor is moved at the preset jogging speed.

 

8.3.1 Preparations
Always check the following before you execute jogging.
 The main circuit power supply must be ON.
 There must be no alarms.
 The Servo must not be in Safe State.
 The servo must be OFF.
 The jogging speed must be set considering the operating range of the machine.
The jogging speed is set with the following parameters.

 

8.3.2 Applicable Tools
 Use the Panel Operator of the Drive
 Use the ESView V4 (Recommended)

 

8.3.3 JOG Operation
Use the Panel Operator of the Drive
Before performing the JOG operation by using the Panel Operator, you shall check and set the relevant parameters properly.
For the method of checking and setting parameters by using the Panel Operator, refers to the section 4.1.4 Parameter Setting Mode.

Following the below steps to jog the Motor.
Step 1 Press [M] key several times to select the Utility Function Mode. 

Step 2 Press [▲] key or [▼] key to select the function number Fn002. 

Step 3 Press [◄] key, and Panel Operator displays as below

Step 4 Press [M] key to Servo ON (supply power to Motor).
Press [M] key again to Servo OFF (not supply power to Motor).

Step 5 Press [▲] key or [▼] key to run the Motor in forward or reverse direction.
Press and hold [▲] key or [▼] key to run the Motor continuously. 

NOTE: The rotation direction of the Motor depends on the setting of Pn001.0 (CCW, CW). The figure above shows the default setting.

Step 6 Press the [◄] key to return to the display of the Fn002.

 

Use the ESView V4
The Motor will operate only while a button is clicked on the ESView V4.

Step 1 Select Run > JOG in the Menu Bar of the ESView V4 main windows

 

Step 2 Read and follow the precautions in the warning box, and then click OK.

 

Step 3 Set the below parameters on the JOG dialog box.

 Pn305 JOG Speed: set the speed for jogging the Motor.
 Pn306 Soft Start Acceleration Time: set the time it takes for the Motor runs to JOG speed.
 Pn307 Soft Start Deceleration Time: set the time it takes for the Motor stops from JOG speed

 

Step 4 Click Servo Off / Servo On for supplying power to the Motor

 

Step 5 Click the button or for running the Motor.

 

Click and hold the button or  can run the Motor continuously, and the Motor can stop running when you release the button.

 

8.4 Motor Operation with a Load
8.4.1 Precautions

 

If you will use a holding brake, observe the following precautions during trial operation.
 Before you check the operation of the brake, implement measures to prevent vibration from being caused by the machine falling due to gravity or an external force.
 First check the Motor operation and brake operation with the Motor uncoupled from the machine. If no problems are found, connect the Motor to the machine and perform trial operation again.
Control the operation of the brake with the /BK (Brake) signal output from the Drive.

 

8.4.2 Preparations
Always confirm the following before you perform the trial operation procedure for both the machine and Motor.
 Make sure that the Drive is connected correctly to both the host controller and the peripheral devices.
 Safety Function Wiring
− If you do not connect a safety function device, keep the Safety Connector plugged into the CN6 port, and the shorting pins on the connector remain in the default state.
− If you are using the safety function, remove the shorting pins on the Safety Connector, and connect the safety function device.
 Overtravel wiring
 Brake wiring
 Allocation of the /BK (Brake) signal to a pin on the I/O signal connector (CN1)
 Emergency stop circuit wiring
 Host controller wiring

 

8.4.3 Operation Procedure
Step 1 Enable the overtravel signals
Refers to the section 7.3.3 Enabling/Disabling the Overtravel Signal.

Step 2 Make the settings for the protective functions, such as the safety function, overtravel, and the brake.
 For details on connecting safety function signals, refers to Chapter 11 STO.
 For details on overtravel settings, refers to the section 7.3 Overtravel Limit.
 For details on holding brake settings, refers to the section 7.5 Holding Brake.

Step 3 Turn OFF the power supplies to the Drive.
The control power supply and main circuit power supply will turn OFF.

Step 4 Couple the Motor to the machine.

Step 5 Turn ON the power supplies to the machine and host controller and turn ON the control power supply and main circuit power supply to the Drive.

Step 6 Check the protective functions, such overtravel and the brake, to confirm that they operate correctly. NOTE: Enable activating an emergency stop so that the Motor can be stopped safely should an error occur during the remainder of the procedure.

Step 7 If necessary, adjust the servo gain to improve the Motor response characteristics. The Motor and machine may not be broken in completely for the trial operation. Therefore, let the system run for a sufficient amount of time to ensure that it is properly broken in.

Step 8 For future maintenance, save the parameter settings with one of the following methods.
 Use the ESView V4 to save the parameters as a file.
 Record the settings manually.
This concludes the procedure for trial operation with both the machine and Motor.

 

8.5 Program Jogging
You can use program jogging to perform continuous operation with a preset operation pattern, travel distance, movement speed, acceleration/deceleration time, waiting time, and number of movements.
You can use this operation when you set up the system in the same way as for normal jogging to move the Motor without connecting it to the host controller in order to check Motor operation and execute simple positioning operations.

 

8.5.1 Preparations
Always check the following before you execute program jogging.
 The parameters must not be written prohibited.
 The main circuit power supply must be ON.
 There must be no alarms.
 The Servo must not be in Safe State.
 The servo must be OFF.
 The range of machine motion and the safe movement speed of your machine must be considered when you set the travel distance and movement speed.
 There must be no overtravel.

 

8.5.2 Operation Description
Program jogging operation consists of two operation patterns (PJOG0 and PJOG1), you can set their relevant parameters respectively. Figure 8-1 shows an example of position-speed timing diagram in PJOG operation.

 

The Drive will operator the Motor repeatedly according to the parameter settings of the two operation patterns until you stop the program jogging operation manually.
You can set the parameters Pn164 and Pn168 to a negative value for reversing the Motor, so that there are four ways of the operation in the program jogging, as is shown in Figure 9-9. 

You shall set the Rotations (Pn164 and Pn168) and Max Speed (Pn165 and Pn169) to a proper value. If the Rotations is set too small or the Max Speed is set too large, it is possible that the maximum speed set cannot be reached. In this case, it is necessary to increase the Rotations or decrease the Max Speed.
