SM1050-2 ENDURO™ ELITE NON-POSITIONER SERVO MOTOR

USER INSTRUCTIONS

Congratulations!

You have purchased the Enduro™ Elite SM1000 series motor that pays for itself with 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
eries is exceptional. This workhorse just won’t quit.

Please read these instructions carefully before installation, operation or maintenance.

General Introduction

The Enduro™ Elite SM1000 Series Servo Motor is designed to meet almost all basic heavy duty and
continuous use requirements of various industrial 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.

™

Elite SM1000

By using a modern technologically advanced microprocessor, Hall sensor and Pulse-Width Modulation
technology, the Enduro™ Elite SM1000 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
plug of the cable from the switch box into the power inlet socket in the back of the motor box.

Wiring

For 220 volt single phase motor follow the diagram below:

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 roughly a circle with a running blinking bar, which means
the motor is now in "ready" status, ready to work or be set.

Slow Starting Speed
Setting up Number 1

1. The "slow period time" = 128milliseconds * 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.

Option A - Setting Slow Starting Speed via Motor Control

a. Keep "▼" button pressed for several seconds, until LED

display indicates "SET.0".

b. Press "▲" button 1 time to indicate "SET.1", which means

"Setting up No. 1".

c. Press "▼" button and LED indicates "SOT.X" (X is 0-9).

Press "▼/▲" to adjust from 0 to 9 according to your own

application. 0 means the quickest. 9 means the slowest. The

manufacturer’s default setting is 0.

d. Setting will be automatically saved 5 seconds after no buttons

are pressed. The motor returns to "ready" status.

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.

A complete and current listing of error messages and trouble shooting can be found at www.endurosaves.com.

E1: Motor Control Error

1. Most E1 error messages occur because of unstable power being supplied to the motor.

• Release the pedal when the E1 error message occurs, then push down again to activate
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 the Hall sensor signal connector and socket (HER indicated) on the circuit board (Five
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.
There is no repair possible and the motor must be replaced.

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, the E3 error message occurs when the motor rotation is stuck by something or blocked
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.

• Remove the obstruction that is prohibiting rotation and the E3 error message should no longer
display.

3. If nothing is blocking the sewing process and the motor can turn freely and the E3 error message
is displayed, it is likely a faulty motor circuit board.

• Replace the motor circuit board and the E3 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. SM109

for 4 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.

ENGLISH - 9

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 the motor is on and the pedal position signal received by the motor circuit board is
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
treadle is already pressed down before the motor is turned on.

• Check the alignment of the sensor versus blocker on the treadle sensor plate. Adjust the position
of the blocker if necessary (see diagram of Proper Replacement of Treadle Sensor).

• 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 (Single channel
sensor for non-positioner motors No. SM68), 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. If after replacing the treadle sensor and the E6 error message continues to appear the motor
circuit board is likely faulty.

• Replace the motor circuit board and the E6 error message should no longer display.

1

1. Remove the 4 screws on the treadle sensor
plate.

3

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

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.
