Cause of The Problem
Status and Measurement
ER0. 9
1. Machine solenoid shorted.
2. Main board’s power transistor is faulty.
Motor still can run, but all output signals and Operation box’s pattern sewing function will be invalid
Please check machine’s solenoids, if any resistance value is 2 Ω less.
Please check all the power transistors, which related to machines’ solenoids.
ER0. 11
1. If parameter【121.ANU】 is set ON, but Auto Needle Up is
malfunction when the power turned on.
Motor still can run, but it automatic starts the clutch mode. All Constant-stitch sewing pattern and trimmer
wiper function will be invalid.
Check Synchronizer’s up position’s signal.
Check main board’s Synchronizer circuitry.
ER0. 14
Using PSU signal without sewing material when【106. PSN】= OFF
Motor stops.
Please check「PSU」sensor circuitry and its signal.
ER0. 15
Using PSD signal without sewing material when【106. PSN】= OFF
Motor stops.
Please check「PSD」sensor circuitry and its signal.
ER0. 51
1. Motor overloads for more than 20 seconds during one sewing.
2. Motor’s coil is defective.
3. Machine head is too crude to rotate smoothly.
Motor stops.
Please check to see if machine head is too heavy to sew.
Please check to see if the sewing material is too thick to sew.
Please check motor’s coils to see if defective.
Please check machine head to see if too crude to rotate smoothly.
Motor rotation icon in display is halting & not moving:
1. Safety switch is either faulty or bad connection.
2. Parameter【075. SFM】setting not match the machine head model.
Motor stops.
Please check the safety switch.
Please check parameter【075. SFM】 setting, make sure it match machine head’s safety switch

POWER OFF
1. AC power shut down or bad connection.
2. Main board OI 1 detect circuitry faultiness.
Motor stops
Please check AC power and connection.
Please check the main board OI circuitry.
EM STOP
1. An emergency stop signal activated when Parameter
【149. IND】= ES.
Motor stops emergently
Please check condition of「IND」signal.
Only restarting power can normally run (it).
