DKS-DDS-DDC: Troubleshooting Drive Errors

Drives play a key role when it comes to handling the speed and torque of electric motors. When using an industrial motor, users and technicians are likely to encounter various errors that may affect their performance. It is important that the operators know the causes and ways to solve these errors. Here are some of the important, common drive error codes that you need to look out for when operating a motor and how to resolve the issues.

".."

The two-dot error refers to the "Watchdog" error. It refers to the non-functional processor in the DKS. It pops up either when the drive lacks a software module, or it has mechanical problems. This can be resolved by installing or replacing the software module or replacing the DKS.  If you’re in need of replacing or repairing your DKS, you should contact Wake Industrial and see about our same-day shipping options.

"18"

This is the “Amplifier Overtemperature Shutdown" error that means the power output stage has an outrageously high temperature detected in the power output stage of the DKS. Before the error, the “50 amplifier over temperature” will appear for 30 seconds before the drive shuts down.

The cause of the error is either the built-in blower on the equipment is not working, or the climate control systems have problems. The problems can be resolved by replacing the DKS, fixing the enclosure climate control system, or the enclosure size.

"19"

The error refers to the overheating of the motor. This can be resolved by having a close look at the motor layout. If the systems have been in use for a prolonged period, then you should check for particles such as dirt, friction, and any physical masses that may have made their way inside the drive systems. You can also monitor the wire to the motor temperature control X6/1; and X6/2 for a proper ground connection or a break.

"20"

This "20" error indicates the bleeder over-temperature shutdown. This appears when regenerated power has become too high. The operator should change the processing cycle and opt for a DKS that has a higher-rated current to address the problem. You can browse the detailed selection of DKS motors Wake Industrial offers here.

"22"

This means the signals on the motor encoder/feedback should be monitored. The error appears when the feedback cable is defective, or it is disconnected. This issue can be addressed by inspecting the feedback cable for any physical crimps or issues. If there is no issue with the cable, the motor will need be inspected next.

"24"

The DKS shows the "24" error if a phase current has exceeded the value of 1.5. If it appears, then look for problems in the motor cable or consult with a supervisor regarding the input parameters.  

"25"

The "25" error flashes when the DC bus voltage reaches a high value (Ud > 475 V). The drive gets temporarily switched to a torque-free state to protect the power stage of the DKS. The causes of this error are the regenerated energy of the braking motor could not be converted quickly enough by the bleeder resistor, or the bleeder circuit was defective. To resolve the error, the operator should opt for a DKS having a higher-rated current. Replacing the DKS is also a recommended troubleshooting solution.

Here's a summary of the error codes, their causes, and troubleshooting tips.

 

Code	Meaning	Causes	Troubleshooting Tips
26	Undervoltage Error	DLC glitches, malfunctioning of the DKS, input power problems	Inspect logic to enable the driver and replace the malfunctioning DKS
68	Brake Fault	The supply voltage for the brake gets produced in the DKS, improper connection or short circuit of the brake or loose or improper connection of the motor	Inspect the supply voltage and the motor cable. Replacing of the motor and DKS
76	Absolute Encoder Error	Incorrect position initialization	Clear the error (establish axis reference), monitor if the new traverse command will cause damage, and inspect the reference position
81	Defective RAM Program	Hardware error in the servo motor drive	The servo drive should be replaced
83	Error in reading the drive data	Hardware glitch in the servo drive	Replace the servo drive
91	Configuration Error	Incompatible hardware and software configurations along with defective, not installed, or incorrect insertion of the plug-in cards	Inspect the plug-in cards or servo drive per the configuration label and replace the software or hardware
92	Uncalibrated Absolute Encoder	The parameters have not been specified and there are defects in the DSF feedback.	Specify or confirm the parameter. The motor should be replaced if required.

 

You can streamline the manufacturing process better by proper error identification. Diagnosing and resolving the motor drive issues only enhances the performance of your servo motors. You can keep your motor operating in top-notch conditions and extend the lifespan of your machinery via preventative maintenance.  If you’re still having trouble, issues, or need a replacement DKS, get in touch with Wake Industrial today.
