4. Quickly speed setting
在In the standby interface, short press the or to set the speed. Short press the
to increase the speed by 100RPM (value increases by 1), short press to decrease
the speed by 100RPM (value decreases by 1), long press ( ) to realize rapid
increase (decrease), the setting parameters are saved automatically.
5. Needle stop positions setting
Long press in the standby interface to set the needle stop positions, and the
parameters will be saved automatically.
6. Parameters setting
Long press and (for around 3S) in the standby interfaceto enter the parameter
setting interface. The first digit nixie tube displays "F" and the second digit nixie tube
does not display (hereinafter referred to as "F interface", which is one of the setting

After entering the F interface, press to change the parameter number, press to
show the corresponding parameter value, and then press to change the parameter
value; If the parameter value is modified, press to save, shows "oK" (as shown in
Figure 6-4), and return to the current serial number display interface. If the parameter
value is not modified, directly return to the current serial number display interface. In
the setting interface, the motor operation will exit to the standby interface.
6.1 Speed controller model modification
Taking speed controller model selection as an example, long press and (for
around 3S) in the standby interface to enter the parameter setting F interface (as
shown in Fig. 6-1), and then short press to change the serial number to B to display
the default parameter value 0 (as shown in Fig. 6-2, corresponding to the flat sewing
computer model). If you want to modify the parameters, you can press to change the
parameter value to 1 (as shown in Fig. 6-3, corresponding to ZB simple type), and
then short press to save. After "oK" is displayed, the parameters are modified
successfully. Then return to the standby interface, power off and replace the governor.
When the power on panel shows no error, the governor is replaced. If there is an error,
please check whether the speed controller model matches or not.

Note: if the error alarm cannot be removed according to the advice, please contact the
manufacturer in time.
If the above problems cannot be solved, please contact the
maintenance personnel.
E4 Abnormal motor Hall
signal
Please check whether the motor encoder plug connection is
reliable, whether the encoder signal wire is broken, and
whether the pin exits or deforms.
E5 Abnormal locator signal
Please turn the hand wheel. If the alarm cannot be eliminated,
turn off the power and power on again. If the alarm cannot be
eliminated, please check whether the encoder / positioner plug
connection is reliable;
Abnormal Hall of motor positioner;
(if the positioner is damaged or the positioning function is not
required, when E5 is reported, press for 3S to close the
needle stop function).
E6 Abnormal speed
controller
If E6 alarm is flashing, please check if the speed controller's
type is match with the b parameter (default matching with the
computerized lockstitch machine type),and adjust the b
parameter to match with the current speed controller.
If E6 alarm is always on, please check whether the speed
controller is inserted and whether the plug-in / pin is loose or
falls off;
If the alarm cannot be eliminated, replace the governor; If the
alarm still cannot be eliminated, the signal of the control box
speed controller may be abnormal. Please contact the
maintenance personnel.
E7 Head safety switch
alarm

(110V control box). If so, please adjust the power supply
voltage to the rated voltage before starting the machine (220V
control box rated voltage: 220V, 110V control box rated
voltage: 110V).
EC System undervoltage
Immediately cut off the power supply and check whether the
power supply voltage is lower than 110V (220V control box) /
55v (110V control box). If so, please adjust the power supply
voltage to the rated voltage before starting the machine (220V
control box rated voltage: 220V, 110V control box rated
voltage: 110V).
EJ Current detection circuit

machine head can be turn on and off normally. If it keep in off,
please replace the button of the machine head.
(the alarm will automatically turn off the complementary stitch
function, but will not affect the motor operation. The alarm
will be cleared automatically after 30s or by pressing )
