Some of these issues can be a simple quick fix, and some may need a technician to conduct serious inquiries: When tachho technicians see this code it is usually a simple fix, it is usually because the unit is not plugged in correctly. So check your plugs first. Drives will continue only as long as there is sufficient power in the link circuit.
Check fuses, the connection and the controller. Do not run drives for longer periods of time at full load because the fan switched off. Hit the reset key once, if the fault does not occur again immediately DO NOT repeatedly hit the reset key as it may cause further damage to motor and drive modules.

Quite possibly a break in the fiber optic cable. The ring is now initialized. This message allows detection of an intermittent break in the fiber optic ring. To continue, activate the clear input.
If error continues, replace fiber optic cable.
Ensure that the DSS card address is properly selected and has not changed. But can the problem be from fiber optic mamual supply? But Why do interrupt the beam exactly when the driver give output?
Please can you give me more information and comments? Hi Yunus, I believe with the fiber optics being connected in series, you will only get the fault on the drive that has the issue.

Make sure that there are no breaks in the fiber optic transmit and receive cables also be sure that they are connected to the proper terminal. The transmit should go to the receive on the atcho drive and vice versa. It is common to have the tips of the fiber optic cable to have fractures but not be broken all the way through.
This type of problem is very difficult to diagnose without being on site at your facility. I am having a slight issue with an Indramat drive unit. Can i please have some advice on what could be causing the problem? I presume this be a short circuit but not sure as to whether this could be within the motor or drive unit?
It could also be a symptom of a bad output and the DC bus will run right to the IGBT which would also throw that fault.

To add to that comment, this is a feature you want working because if there is a bad short circuit anywhere, allowing to enable may cause catastrophic damage to the unit, potentially past the point of any kind of repair.
If you have the equipment in house, I would recommend swapping for another unit of the same model number to verify that your problem is in the drive, and not something from the motor or power supply throwing that fault.
I hope this is a help for you. If you need further assistance, or would like to send a unit in for evaluation, please call or go to http: I also have a small panel with 5 indicators which i believe all need to be on.
Thankyou very much for the advice.
