What to do if DURKOPP ADLER Sewing Machine shows internal EEprom defective?
If the internal EEPROM is defective in your DURKOPP ADLER Sewing Machine, replace the control.
What to do if the sewing motor plug (AMP) is not connected on my DURKOPP ADLER 867 Sewing Machine?
If the sewing motor plug is not connected on your DURKOPP ADLER Sewing Machine, check the connection and plug it in if necessary. You may also test sewing motor phases (R= 2.8 ?, high impedance to PE). Replacing the encoder, sewing motor, or the control might also resolve the issue.
Why is my DURKOPP ADLER 867 Sewing Machine showing a low voltage failure?
If your DURKOPP ADLER Sewing Machine shows a low voltage failure (1st threshold), it means the mains voltage is below 180V AC. Check the mains voltage, stabilize it, or use a generator to resolve this issue.
What to do if DACextension box is not responding on DURKOPP ADLER 867 Sewing Machine?
If the DACextension box is not responding on your DURKOPP ADLER Sewing Machine, check the connection cables and the LEDs of the DACextension box. A software update might also be necessary.
What to do if DURKOPP ADLER Sewing Machine shows low voltage warning?
If you're getting a low voltage warning on your DURKOPP ADLER Sewing Machine because the mains voltage is below 180 V AC, you should first check the mains voltage. If it's consistently low, consider stabilizing the mains voltage or using a generator to ensure a stable power supply.
What to do if sewing motor encoder plug (Sub-D, 9-pin) is not connected in DURKOPP ADLER 867 Sewing Machine?
If the sewing motor encoder plug is not connected on your DURKOPP ADLER Sewing Machine, connect the encoder cable to the control using the correct connection.
What to do if DA stepper card 2 is not responding on DURKOPP ADLER 867 Sewing Machine?
If DA stepper card 2 is not responding on your DURKOPP ADLER Sewing Machine, check the connection cables and the LEDs of the DACextension box. A software update might also be required.
How to fix software version error on DURKOPP ADLER 867 Sewing Machine?
If you encounter a software version error on your DURKOPP ADLER Sewing Machine (DAC classic only), try updating the software. If the issue persists, consider replacing the control.
Why is speed limited due to insufficient mains voltage on DURKOPP ADLER 867 Sewing Machine?
If the speed is limited on your DURKOPP ADLER Sewing Machine due to insufficient mains voltage, check the mains voltage.
What to do if DA stepper card 1 encoder plug (Sub-D, 9-pin) is not connected on DURKOPP ADLER 867?
If the DA stepper card 1 encoder plug is not connected on your DURKOPP ADLER Sewing Machine, connect the encoder cable to the control using the correct connection.
