1. Safety Precaution
When install and operate HVP-20 MINI Servo Motor, precaution must be taken as the following.
This product is designed for the industrial sewing machines and must not be used for other purposes.
(1). Work environment :
(a). Power voltage:
Only use Power Voltage indicated on the name plate of the HVP-20 in ±10 % ranges.
(b). Electromagnetic pulse interference:
To avoid the abnormal running, please keep the product away from the high electromagnetic
machine or electro pulse generator.
(c). Temperature:
1. Please don’t operate in room temperature is above 45°C or under 5°C
2. Avoid operating in direct sun light or outdoors area.
3. Avoid operating near the heater.
4. Avoid operating in the area which humidity is 30% less and 95% more, also keeps away from
dew area.
(d). Atmosphere:
1. Avoid operating in dusty area, and keeps away from corrosive material.
2. Avoid operating in evaporative or combustible gas area.
(2). Safety in installation :
(a). Control box: Follow the instruction in this manual for proper installation.
(b). Accessories: Turn off the power and unplug the cord before mounting any accessories.
(c). Power cord:
1. Avoid power cord being applied by heavy objects or excessive force, or over bend.
2. Power cord must not set to be near the V-belt and the pulley, keep 3 cm space or above.
3. Check the outlet voltage before plugging the cord, make sure it match the voltage shown on
the name plate of the HVP-20 in ±10 % ranges.
Attention : If the control box is AC 220V system, please don’t connect to the AC 380V
power outlet, otherwise the error code will occur. If that happened,
please turn off the power switch immediately and check the power voltage.
Continue supply the 380V power over 5 minutes might damage the fuses
(F1,F2) of EMI board and burst the electrolytic capacitors (C4,C5) of power
board and even might endanger the person safety.

(d). Grounding:
1. To avoid the static interference and current leakage, all grounding must be done.
2. Use the correct connector and extension wire when connecting ground wire to Earth and
secure it tightly.
(3). Safety in operating :
(a). When turn on the machine in the first time, use low speed to operate and check the correct
rotation direction.
(b). During machine operation, don’t touch any moving parts.
(c). All moving parts must use the protective device to avoid the body contact and objects insertion.
(4). Safety in maintenance and repairs :
Power must be turned off first, when:
(a). Uninstall the motor or the control box, or plug and unplug any connector.
(b). Turn off the power and wait 5 minutes before opening box cover.
(c). Raising the machine arms or changing needle, or threading needle. (Shown as above)
(d). Repairing or doing any mechanical adjustment.
(e). Machines rest.
(5). Regulation in maintenance and repairs :
(a). Maintenance and repairs must be done by trained personnel.
(b). Don’t cover up motor’s ventilation, it can cause motor over heated.
(c). Don’t use any objects or force to hit the product.
(d). All spare parts for repair must be approved or supplied by the manufacturer.
(6). Danger and Caution Signs :
Risks that may cause personal injury or risk to the machine are marked with
this symbol in the instruction manual.
This symbol indicates electrical risks and warnings.
(7). Warranty information :
Manufacturer provides a limited warranty in respect of the products covered for a
period of 18 months for any defects arising in the normal course.

(4). Speed control unit Forward / Backward function & force adjustment :
Delivery condition the inside torsion spring “E” is in position „1“.
After the adjustment of the outside springs (chap.3) the inside torsion spring (E) can be adjusted additionally.
a). Machine with foot lifter:
For machines with foot lifter solenoid, the lower blade of the spring must be placed in position1.
This causes a clear position for pedal half heeling position for sewing foot lifting without thread trimming.
The thread trimming will follow with pedal full heeling.
In this position of the spring blade the pedal force forward is lower than in position 2.
Attention: The parameter 70 has to be set onto OFF for machines with foot lifter solenoid.
b). Machine without foot lifter:
For machines without foot lifter solenoid the spring blade can be brought from position 1 to position 2.
Push with a small screw driver through the hole (F) and the blade will jump from position 1 to position 2.
The pedal forward force is higher in position 2 than in position 1.
Attention:
1. For machines without foot lifter solenoid the parameter 70 has to be set onto ON, that the thread trimming
happens in half heeling position of the foot pedal.
2. The reverse positioning of the springs blade (E) from position 2 to 1 can only be made after opening of the
speed control unit housing from inside.

(a). Install the synchronizer with the copper
screws on the machine head.
WARNING:
The screws must be copper, if using iron, it will cause the needle positioning
abnormal and also cause the 2 magnets in the hand wheel to be demagnetized.
(a). Install the N pole and S pole magnets inside the hand wheel.
WARNING:
The N pole magnet has a red dot on the magnet.
If the N pole and S pole magnets installed incorrectly, it will cause the up and

(a). Install the hand wheel on the machine head shaft, align the screw of the hand wheel on the flat area of
the machine head shaft and secure all related screws.
WARNING:
Make sure that the hand wheel don’t touch the synchronizer (leave a 0.5 mm space),
or else the synchronizer will be damaged by the friction during sewing.

WARNING: Please leave
a 0.5 mm space between
the synchronizer and the
hand wheel..

(8). Needle position adjustment :
Index dot
(a). After installing the synchronizer, toe down the pedal
and let the machine running few stitches, then check
the needle position.
(b). If motor stop at up position, the top white dot on hand
wheel should be aligned with the index dot on the
sewing machine.
Note : The dots in some machine head’s hand wheel
have different colors or different locations.
