SM645-1P & SM645-2P ENDURO™ PRO SERVO MOTOR WITH
POSITIONER USER INSTRUCTIONS
Congratulations!
You have purchased the Enduro™ Pro SM600 series motor that pays for itself with a remarkable 60%
to 80% energy savings compared to clutch motors. With the high and rising cost of electricity, you just
can’t afford to run a clutch motor any longer. The power and dependability of the brushless Enduro™
Pro SM600 series is adequate for light duty sewing.
Please read these instructions carefully before installation, operation or maintenance.
General Introduction
The Enduro™ Pro SM600 Series Servo Motor is designed to meet almost all basic light duty requirements
of various commercial sewing machines. It utilizes extremely powerful rare-earth Neodymium permanent
magnets. The motor produces almost no noise, saves energy and is brushless, speed adjustable and
durable. It provides a high starting torque even at low speed or from a complete stop.
By using a modern technologically advanced microprocessor, Hall sensor and Pulse-Width Modulation
technology, the Enduro™ Pro SM600 series can be set to rotate at different maximum speeds, in either
normal or reverse directions, and can start with different accelerating speeds. It will stop automatically with
any interruption such as in-line voltage, electrical surge, radio frequency interference or overloading. It
is fully protected by the software and will give error messages indicating which problem is encountered.
It even works well in environments with an unstable electrical power supply.
CAUTION
1. Remove your foot from the pedal when turning the power ON.
2. Turn the power switch OFF before replacing or threading the needle.
3. Turn the power switch OFF when leaving the machine.
4. When performing maintenance on the sewing machine, turn the motor power switch to
the OFF position. Remove the power cord from the back of the motor to completely
disable all power to the sewing machine.
5. Always ground the grounding wire.
6. Always turn off the power switch before connecting or disconnecting each connector.
7. To avoid an accident, do not alter this motor and control box.
Warranty
This product is covered with a 1 year limited warranty. If the motor fails to perform its designed function
due to manufacturer’s defects, contact the place you purchased it from for repair or replacement.
This warranty does not cover defects due to dropping, power surge, spikes or misuse.
Installation
Put the mounting bracket of the motor upwards to the bottom of the tabletop and x the motor to the
tabletop with the bolts provided. Connect the treadle rod with the connecting rod joint. Install the female

Wiring
For 110 volt single phase motor follow the diagram below:
For 220 volt single phase motor follow the diagram below:
ENGLISH - 3
Note: When wiring the motor to the power source, connect both the black and white wires to
achieve 220 Volts (green to ground). If you are in an area (China / Europe) that supplies 220 Volts
from a single lead, then connect the power source to the black wire. The white wire will then be the
neutral and the green wire will be the ground.
Setting Up
Turn on the power switch located on the switchbox. The display
will show "P.d", which means the motor is in "ready" status,
ready to work or be set.
default "ready" status
Ready Status
"P.d" is the factory default "ready" status setting and means the
needle position setting is POSITION DOWN. "P.d" is "ready"
status while default setting is not changed.
default "ready" status
Once the needle position setting is changed to "P.u" (which
means the needle position setting is POSITION UP), then "P.u"
becomes the "ready" status.

1. The "slow period time" = 128 milliseconds
* X, (slow starting setting), X = 0~9 (as setting up in
the motor).
2. Example: The treadle is depressed approximately half way down producing a motor speed
of about 2,000 RPM and if the Slow Starting is set at 9, then the time from 0 to 2000RPM is
theoretically 128 milliseconds X 9 = 1152 milliseconds, plus the electrical-mechanical delay
which is about 0.8 seconds.
3. If the Slow Starting is set at 0, the "real starting time" and time from 0-2000RPM is about 0.8
seconds, which is due to the unavoidable electrical-mechanical delay.

Either "P.d" or "P.u" will indicate
"ready status, depending on how
the needle position is set.
is POSITION DOWN when the sewing machine is stopped.
This is the default factory setting.
b. Press "▼/ ▲" to switch the setting of the needle position
between either UP or DOWN.
default "ready" status
When positioner sensor is set correctly to the UP position and you stop sewing, the needle will stop
at the UP position. If you then heel the treadle, the motor will rotate to put the needle in the DOWN
position.
When the position sensor is set to the DOWN position and you stop sewing, the needle will stop at the
DOWN position. If you then heel the treadle, the motor will rotate to put the needle in the UP position.
Error Messages and Trouble Shooting
When an error message appears on the display the motor will stop automatically to protect the electronics
of the motor and most importantly, to protect the motor circuit board.
If an error message occurs be sure to repeat the action that caused the error message. Many times if
you reactivate the treadle and start the motor again, the error message will clear indicating this was a
False error message requiring no further action.
There are two types of error messages:
1) False error messages
2)
True error messages if the error is repeated.
False errors messages are common in areas where the electricity being supplied is unstable due
to uctuations, interference and spikes in electrical power supply to the motor. If these False error
messages happen quite often it is recommended to contact a local electrician to see if the power
supplied to the motor can be ltered. Doing so will eliminate False error messages.
True error messages do occur occasionally indicating a problem with an electrical component, the
motor circuit board and on a very rare occasion, a faulty motor.

9 - ENGLISH
E1: Motor Control Error
1. Most E1 error messages occur because of unstable power being supplied to the motor.
• Release
the motor. If the E1 error message no longer appears this was a False error due to unstable
power.
2. If the E1 error message continues to appear:
• Replace the motor circuit board with a new motor circuit board. Once the motor circuit board
is replaced the E1 error message should no longer display.
3. If
the E1 error message still appears after changing the motor circuit board, this is a very rare
occurrence due to a faulty motor.
E2: Motor Phase Signal Error (Hall Sensor Error)

1. It is possible to receive an E2 error message from unstable power which means it is a False
error and the problem should resolve on its own.
2. Check
Pin connector / socket), to make sure the 5 wires are connected to the board properly.
3. If the E2 error message continues to appear the motor is faulty and will not function properly.
E3: Motor Protected Against Over Current
1. It is possible to receive an E3 error message from unstable power which means it is a False
error and the problem should resolve on its own.
2. Usually
by a heavy load when sewing. When this happens, more and more electrical current is driven to
the motor until the electrical current exceeds the amount allowed by the motor. If this happens,
the E3 error message is displayed and the motor is stopped to protect the motor from overload
or burn out.

E4: Circuit Board Error in Memory Reading and Writing
1. It is possible to receive an E4 error message from unstable power which means it is a False
error and the problem should resolve on its own.
2. If the E4 error message continues to display it indicates a faulty motor circuit board.
• Replace the motor circuit board and the E4 error message should no longer display.
E5: Display Module and Control Module Communications Error
1. It is possible to receive an E5 error message from unstable power which means it is a False
error and the problem should resolve on its own.
2. E5 error message indicates a faulty LED display
• Check connections on the LED display module to be sure it is securely fastened to the motor
circuit board. If the E5 error message no longer displays, then the connection to the motor circuit
board was loose.
• If the E5 error message continues to appear then replace the LED display module (No. SM627
for 2 digit readout) and the E5 error message should no longer display.
3. If the E5 error message continues to appear it indicates a faulty motor circuit board.
• Replace the motor circuit board and the E5 error message should no longer display.

E6: Pedal Position Sensor Error
1. It is possible to receive an E6 error message from unstable power which means it is a False
error and the problem should resolve on its own.
2. While
abnormal, it is possible to get the E6 error message. This is most common because of a faulty
treadle sensor, misalignment of the sensor versus blocker, or improper operation such as the

• Check the snap on connector of the treadle sensor and be sure it is securely attached. If the
E6 error message no longer appears the connector was loose.
• If the E6 error message continues to appear, then replace the treadle sensor (Dual channel
sensor for positioner motors No. SM76), and the E6 error message should no longer display.
• When replacing the treadle sensor be sure it is properly aligned. If the treadle sensor is not
aligned properly you may have a problem with the motor continuing to run after releasing the
treadle (see diagram of Proper Replacement of Treadle Sensor).

3. Check the relative position of the sensor
and light blocker. If the light blocker is in a
position that has blocked the light when the
treadle is not pushed down, the motor will
rotate. Adjust the blocker position if necessary
by loosening the screw and tightening it again.
2. Check the channel sensor. It should have
a red light when the cable is connected to the
motor circuit board and the motor is powered
on. Check the cable connection if there is no
red light.
4. Change the sensor if necessary by
unscrewing and reinstalling the two screws.
Then connect the cable to the motor circuit
board. The red light should appear when the
motor is powered on indicating it is working.
