10.2.2 Error messages
Code Possible cause Remedial action
1000 Sewing motor encoder plug
(Sub-D, 9-pin) not
connected
• Connect encoder cable to
the control, use correct
connection
1001 Sewing motor error: Sewing
motor plug (AMP) not
connected
• Check connection and plug
in, if necessary
• Test sewing motor phases
(R= 2.8 Ω, high impedance
to PE)
• Replace the encoder
• Replace sewing motor
• Replace the control
1002 Sewing motor insulation
fault
• Check motor phase and
PE for low-impedance
connection
• Replace the encoder
• Replace sewing motor
1004 Sewing motor error:
Incorrect sewing motor
direction of rotation
• Replace the encoder
• Check plug assignment
and change, if necessary
• Test motor phases and
check for correct value
1005 Motor blocked • Eliminate stiff movement in
the sewing machine
• Replace the encoder
• Replace the motor
1006 Maximum speed exceeded • Replace the encoder
• Perform reset
• Check machine class
(parameter t 51 04)
1007 Error in the reference run • Replace the encoder
• Eliminate stiff movement
in the sewing machine
1008 Encoder error • Replace the encoder
