(Sub-D, 9pol) not connected
• Connect encoder cable to
the control, use the correct
interface
1001 Error Sewing motor error
Sewing motor plug (AMP) not
connected
• Check connection and
plug in
• Test sewing motor phases
(R = 2.8 Ω, high impedance
to PE)
• Replace encoder
• Replace sewing motor
• Replace control
1002 Error Sewing motor insulation error • Check motor phase and PE
for low-impedance
connection
• Replace encoder
• Replace sewing motor
1004 Error Incorrect sewing motor direction
of rotation
• Replace encoder
• Check motor plug
assignment and change it if
necessary
• Check wiring in machine
distributor and change it, if
necessary
• Test motor phases and
check for correct value
1005 Error Motor blocked • Eliminate stiff movement in
the sewing machine
• Replace encoder
• Replace sewing motor
1006 Error Maximum speed exceeded • Replace encoder
• Perform reset
• Check machine class (t 51
04)

1010 Error External synchronizer plug
(Sub-D, 9-pin) not connected
• Connect cable of external
synchronizer to control,
make sure that interface
(Sync) is correct
1011 Error Encoder Z pulse missing • Switch off the control, use
handwheel to turn, and
switch on the control again
• If error is not corrected,
check encoder
