Corrective
• Check for stiff movement
• Replace encoder
• Replace motor
• Replace encoder
• Replace the control
• Replace encoder
• Check if plugs have been mixed up
• Check the wiring in the machine distribu-
tor and change it if necessary
• Check for stiff movement
• Replace encoder
• Replace motor
• Replace the control
• Perform software update
• Check selection of class
• Check motor phase and PE for low-
impedance connection
• Replace encoder
• Replace sewing motor
• Perform software update
• Check selection of class
• Check for stiff movement
• Replace encoder
• Replace motor
• Check reference switch
• Disconnect the stepper motor plugs;
if error persists, replace control
• Disconnect motor plug; replace control if
error is not corrected: Replace the control
