The external pulse encoder (IPG/HSM) is defective or not connected. Please check the cable connection to the control box! If necessary, replace the IPG/HSM.

The voltage at the B18 socket can be changed from 5V to 15V using parameter F362, or a jumper on the circuit board, depending on the type of control box. The impulse encoders (IPG/HSM) are only designed for 5V and can be impaired or damaged.

For more details, a second error number is shown toggling in the display:
001 Wrong counting of G-Pulses
002 Signal for internal Sync is missing
003 No Sync after one rotation (positive direction)
004 No Sync after one rotation (negative direction)
005 Signal of external Sync is missing
006 Commutation error

The Line voltage is too low, or the time between power Off and power On is too short. Check if the power cord is connected securely to the power outlet. The fault can be triggered by a defective contact or by a short-term power failure of the line voltage.

The motor does not reach the desired speed

• Check, if the machine is mechanically blocked or hindered. (Run/sew without material)
• Check all connection cables and plugs on the machine.
• The error can occur, when trying to sew too thick/strong material. Where applicable, modify the gear ratio of the drive belt in order to obtain a higher torque. Keep the maximum permissible motor speed in mind!
• Verify, that the motor is sufficiently dimensioned for the application.
• Verify, that the correct motor parameter F-467 was selected. (AB6xx, AB425S)
• Check, if the tension of the drive belt is too high/too low.
• Install a different motor of identical build, to check if the motor intself is defective.

Control disturbed by lack of grounding or loose contact.

• If the error occurs sporadically, check whether the controller is sufficiently grounded, or if the mains supply has possible loose contact.
• If the error occurs immediately after power on, you must send in the control for repair.

Motor transistor overtemperature (AB600A, AB220A, AB320A, DA320G, FP220A, FP320A)

• Check, if the machine is mechanically blocked or hindered. (Run/sew without material)
• Check all connection cables and plugs on the machine.
• The error can occur, when trying to sew too thick/strong material. Where applicable, modify the gear ratio of the drive belt in order to obtain a higher torque. Keep the maximum permissible motor speed in mind!
• Verify, that the motor is sufficiently dimensioned for the application.
• Verify, that the correct motor parameter F-467 was selected. (AB6xx, AB425S)
• Check, if the tension of the drive belt is too high/too low.
• Install a different motor of identical build, to check if the motor intself is defective.

24 V power supply unit overload
The error indicates that a connected load of the 24V power supply requires too much power. First, remove the 37-pole connector. If the error no longer occurs, you need to check the connected magnets or solenoids. If the error is still displayed, remove gradually all other cable connections from the controller. If the error is still displayed, the controller must be repaired.

Too much data for the EEPROM or Flash memory
Please send the controller for repair.

EEPROM or flash memory defective
Please send the controller for repair.

Output transistor short circuit (Output FL, VR, M1, M2, M3, oder M4)
The error indicates that a connected solenoid or valve has a short circuit. First, remove the 37-pole connector. If the error no longer occurs, you need to check the connected magnets or solenoids. If the error is still displayed, the control must be repaired.

Power transistor thermal overload
One of the connected magnets or solenoids requires more power than permitted. Thereby, the thermal load of the transistor is too high. Remove the 37-pole connector from the controller. If the problem does not appear anymore, check the connected loads. If the error is still visible, remove all connecting cables. If the error still appears, the controller must be repaired

Output transistor short circuit on M5, M6, M7, M8, M9, M10, or M11
The error indicates that a connected solenoid or valve has a short circuit. First, remove the 37-pole connector. If the error no longer occurs, you need to check the connected magnets or solenoids. If the error is still displayed, the control must be repaired.

Thread cutter did not reach the end position
During the thread cutting operation is a timer running. If the thread trimming was not completed by the time monitoring the output is switched off in order to prevent destruction of the magnet. Check the setting of the needle up position and change them if necessary.

Mains overvoltage: The mains voltage is greater than 290 V rms.
If the error message occurs sporadically, power surges are present. This can be caused by the activation of voltage generators in case of power failure. This is not a fault of control, but a protection mechanism to prevent the destruction of the power input of the control. If the fault is always shown, the controller must be sent for repair.

Internal communication error with intermediate circuit
Please check with us or an authorized service center, if a possibly software update is available. If not, the control must be repaired.

001 ERRVAR_STARTINIT HighSide not programed or not running
002 ERRVAR_INITPARATOZWK HighSide no responese during parameter communication
003 ERRVAR_SENDTXDFRAME1 HighSide no responese during parameter communication
004 ERRVAR_SENDTXDFRAME2 HighSide no responese during parameter communication
005 ERRVAR_MOTORTEST_VAL1
006 ERRVAR_SENDTXD Highside-Processor no response

Mains voltage too low: The mains voltage was less than 120 V eff.
If the error message occurs sporadically, low mains voltages is the problem. This can be caused by a poor power supply. This is not a fault of control, but a protective mechanism to ensure trouble-free running of the motor. If the fault is always shown, the control must be sent for repair.

The indirect d.c. converter could not be loaded on the necessary voltage
Probable cause is a too frequent switching on / off the power in a short time. Switch off the control and  let it cool down. This may take up to 3 minutes depending on the outside temperature. If the problem still occurs frequently, please contact us!

The indirect d.c. converter voltage is higher than 450V
Possibly the braking resistor has failed. The controller has to be repaired!

No motor is connected, inverter is defective or a motor phase is missing
Check the motor cable or replace the motor. If the fault is still present the control must be sent for repair.

The motor speed is too high
The set maximum speed was exceeded. Check the encoder cable of the motor, or replace the motor completely. If the error is not gone, the controller must be repaired!

Error in the 5 V power supply
Remove all connected cables. If the error is gone, check the connected consumer. If the error is still present, the controller must be sent for repair!

The EB401 analog value out of range
Check the connection of the EB401. Replace the EB401. If the error still exists, the controller must be repaired!

Reference sensor not recognized
Please check whether the external reference sensor (IPG/HSM) is plugged in or is defective. If you do not need a reference sensor you can deactivate the function (F270=0).

Handwheel sensor not recognized
Please check whether the external handwheel sensor is plugged in or is defective.

Wrong error number
An unknown or wrong error number was set by software. Please contact us.

Variocontrol Timeout
The variocontrol display is not reacting. The busy signal from the display is on for at least 5sec. Please try to replace the variocontrol (in most common cases V820). Another reason for problem is that you have to power off the control box at least for 5sec before power on.
