Zoje Error Codes, SunStar and JACK H2, A2S Explained

Written by Aashu, owner of Stitch Partner. These Zoje error codes and the JACK and SunStar lists below come from official manuals, and we have supplied machines and spares to tailors and garment units since 1989.

Short answer: Chinese servo machines share a pattern: codes about voltage (low or high supply), motor blocked (jam or plug) and encoder or hall signal (motor plug). Check the mains, free the handwheel, reseat the motor plugs, then restart. The exact code numbers differ by model, so use the right table below.

First, note the exact code on the panel. Then switch off and reseat the plug named in the table. After that, restart and test on scrap cloth. However, if the same Zoje error code returns, stop restarting, because repeated faults can damage the board. Instead, check the motor cable and the supply voltage. Finally, replace a part only when the plug, cable and supply are fine.

JACK H2 (Err-xx)

Err-01 hardware overcurrent; Err-02 software overcurrent; Err-03 low voltage; Err-04 overvoltage when stopped; Err-05 overvoltage while running; Err-07 current detection circuit; Err-08 motor stuck; Err-09 brake circuit; Err-12 initial motor angle; Err-13 encoder signal; Err-14 main board EEPROM; Err-15 motor overspeed; Err-16 motor reversal; Err-18 motor overload; A-UP head tilt alarm. Fix pattern: switch off, wait 30 seconds, restart; replace the controller if it repeats.

JACK ZB-A2S (numbering differs from A4)

Err-01 hardware overcurrent; Err-02 software overcurrent; Err-03 undervoltage; Err-04 overvoltage; Err-05 current detection circuit; Err-07 motor stalled; Err-08 brake failure; Err-09 panel communication; Err-10 motor initial angle; Err-12 motor encoder signal missing; Err-13 main board EEPROM; Err-14 EEPROM fault; Err-15 motor overspeed. Compare with the A4/K4/A5 table, where Err-08 means motor blocked.

JACK JK-T1377E

Err-01 and Err-02 overcurrent (switch off 30 seconds, replace controller if repeated); Err-03 undervoltage; Err-04 and Err-05 overvoltage; Err-06 solenoid wiring; Err-07 current detection; Err-08 motor jam (check the motor plug and foreign objects); Err-09 brake circuit; Err-10 panel communication; Err-11 needle-stop signal (check the synchronizer plugs); Err-12 motor angle detection; Err-13 motor hall signal; Err-23 locked rotor.

Zoje error codes: WR580

Code Meaning What to do
E10 Under-voltage while running Check earthing and the current sampling circuit
E11 Motor HALL_A signal lost Check the motor plug
E12 Motor overload Check for a stuck machine, frequent stop-start
E13 / E14 / E16 EEPROM, current detection, OZ circuit error Control board service or replacement
E15 Pedal zero position over limit Set the pedal zero again
E17 Motor rotating in reverse Check phase order and signal line
E18 Motor test angle error Check phase order; motor stuck

SunStar and Zoje error codes: SPS/E-BS1201H bartack

Er03 needle bar position; Er04 drive limit; Er05 and Er55 cannot reach X origin in time; Er06 Y origin; Er07 ROM version mismatch; Er13 fan failure; Er14 main motor type recognition; Er15 synchronizer contact error; Er16 origin cable missing or XY sensor fault; Er36 low air pressure. Origin and synchronizer faults are usually sensors or cables.

Which part fixes Zoje error codes?

Voltage codes need a stabiliser first. Motor and hall codes point to the motor cable, then the motor. For a full set, see our universal direct-drive servo motor और यह servo control board. Source: Zoje WR580 manual.

To prevent these faults, first keep the machine clean and oiled. Also, use a stabiliser, because unstable mains voltage causes many codes. In addition, never pull on the plugs, since loose or damaged cables cause repeat errors. Moreover, switch off before you unplug anything. Therefore, a few minutes of care each week saves costly repairs. Finally, keep a note of every code and the date, so you can spot a pattern.

However, some faults need a technician. For example, a burnt smell or a blown fuse means you should stop at once. Similarly, repeated overcurrent codes point to a failed part. Because of this, do not open a live control box. Instead, send us the model number and code on WhatsApp. Then we can suggest the right part quickly.

अक्सर पूछे जाने वाले प्रश्न

Do JACK H2 and A4 share the same codes? They are similar, but not identical. Err-08 is motor stuck on both, however other numbers differ.

What does Zoje E11 mean? The hall signal from the motor is lost. So reseat or replace the motor plug.
