Before Contact

Q: What do I need to prepare before contacting us for after-sales service?

Please refer to the serial number first to contact us on support. Contact us the error codes or contents for any error.

Q: Why does the Robot still wobble slightly even after the fixed fixture is installed?
It is designed to protect the Robot motor and prevent gear damage during transportation.

Q: Where is the serial number and error code?

A serial number is labeled or incised mainly on the lower part of connectors of robot/aligner, and the side of the LED display of a controller.
Error codes are displayed on a controller's LED display.

Maintenance

Q: How often should do the Maintenance?

Recommend once a year, but depends on model type. Please confirm the Maintenance manual.

Troubleshooting

Q: The controller does not display anything after the power-on. Why？

Ensure that the power supply is as specified in the specification.
When the EMG terminal is open, the power will not be turned on.
Please check the interlock function and the power up procedure in the specifications.

Q: Why does the controller's fuse blow after powering on?
Because the controller's power supply has positive and negative polarity, please ensure the polarity is correct before wiring.

Q: The speed is changed using the teaching box, but returned to the original speed after the power-on again. Why?

You cannot change speed if the input speed value is out of the setting range.
Data writing is required after setting the speed.
Please follow the procedure to write to EEPROM.
See the Instruction Manual as the procedure varies depending on the models.

Q: Error 08 occurs when the robot is moved up and down with the arm extended. Why?

When the arm is extended, the vertical movement amount is restricted by the setting.
Check the operating range and change the setting of vertical movement amount in accordance with the Instruction Manual.

Q: Why is the speed of the G-series robot very slow when executing ORG to return to the origin after clearing an error?
Because the G-series robot has a movement restriction zone. Once the arm leaves this zone, the speed will return to normal. return to normal.

Communication Software

Q: No response is returned by using the communication software. Why?

1.If other software is running, close it.
2.Ensure that the communication port of PC is opened.
3.Ensure that the opened port is available.
4.Ensure that the communication cable specifications are the same as those 5.specified in the Control Specifications.
6.Ensure that the select switch is set to position 0.
7.Ensure that the display of the teaching box is off.
8.The communication is not available with the teaching box on.

Q: How do I back up the controller data?

You can save data to PC with the accompanying software JELDATA3 and the dedicated communication cable.

How to use JEL DATA3?

Q: What is "body number"?

A body number is an identification number to identify the corresponding controller to output commands when several controllers are connected.
In a standard setting, a robot is set to body number 1 and an aligner to body number 2.

Q: How should the machine body numbers be assigned when configuring the Robot, flipping , and Aligner at the same time?
Robot as No. 1, flipping as No. 2, and Aligner as No. 4.

Q: Why does an abnormal alarm occur and cannot be cleared after 5-axis horizontal 
multi-joint clean room robot GTFR installation is completed and power is supplied?
5-axis horizontal multi-joint clean room robot GTFR is equipped with 
CE safety standard configurations. Please refer to the circuit configuration in the specifications for

Q: Why can't 5-axis horizontal multi-joint clean room robot GTFR use function block?
5-axis horizontal multi-joint clean room robot GTFR has switched to being controlled by 
JEL DATA 5 software, which does not support this function.

Air entered from the supply port generates the Cyclone effect.
Supply air is discharged to the atmosphere between the suction surface and the wafer.
As a result, an air layer is generated between the cyclone pad and the wafer, which enables to lift the wafer without contact.

Characteristics：

Bernoulli pad type or Cyclone pad type is selectable depending on the wafer condition.

1.Bernoulli pad type

● Low cost end-effector for thin or warped wafers
● Capable to handle various sizes or types of wafers
● Wafers can be lifted with low stress to minimize damage
● Thickness of the end-effector can be reduced

2.Cyclone pad type

● Cyclone pads (Dia: 25mm; Thickness: 2.5mm) are used
● Capable to handle various sizes or types of wafers, and available for the Bernoulli type aligner
● Stronger holding of wafers compared to the Bernoulli type end-effector

Edge-grip end effectors

are used to secure the outer edge of the wafer with multiple clamps.

The wafer can be fixed in place using methods

such as cylinders or springs.

This technique is suitable for transporting wafers where contact

with the processed surface is not allowed, as well as for transporting

thin wafers such as MEMS wafers.

When vacuum adsorption could cause stress on the adsorption surface and potentially damage

the wafer, edge gripping is preferred.
