Hi, Can you use the treadmill speed controller ? Or you could by a AC/DC invertor drive , http://www.inverterdrive.com/group/DC-Thyristor-Drives/SSD-507-Eurotherm-Shackleton-Rapier-Drives-503-504/default.aspx
Thats a link for a possible option for you , you often see them in exchange and mart or Craigs List .
hope this helps, please rate accordingly .

I have a herritage t101, it displays the Ls error and has no drive whatsoever but was working a few month back


The SCR lower board is designed with diagnostic LED lights. The LED's are color coded according to
their specific function. Green indicates a properly operating treadmill; the green lights should always
be ON when power is supplied to the treadmill. Yellow indicates a treadmill function. Red indicates a
treadmill malfunction. Here is a list of each LED and what it signifies:
MOTOR (yellow) - The MOTOR LED illuminates when dc (direct current) voltage is sent to the drive
motor. The LED gets brighter when the dc output is increased.
RLC (yellow) - The RLC (R = Reactance / L = Inductance / C = Capacitance) LED illuminates when
the filtering system is properly working. The filtering system includes the capacitor and filter choke. If
there is a short in either component then the RLC light will not come on.
DN & UP (yellow) - The DN and UP LED lights tell us if the elevation DN and UP relays are
functioning properly. When the LED lights, it tells us that the relay has energized and is sending high
voltage (110vac or 220vac) to the elevation motor.
AC PWR (green) - The AC PWR (Alternating Current Power) illuminates when AC line voltage is
delivered to the treadmill. It then passes through the in-line fuse (110)/s(220) and lights the AC PWR
LED.
+12V (green) - When the proper AC voltage is delivered to the treadmill, passes through the in-line
fuse/s, through the full wave bridge rectifier (changes AC to DC), through the transformer (steps down
DC to +12vdc) then the +12V LED lights.
This the board LED, who control the signal for Main Motor+Elevation Motor. You must see, the LED DN+ UP( both will be Lit) in any position down or Up.
2) The RELAY board is designed with diagnostic LED lights. The LED's are color coded according to
their specific function. Green indicates a properly operating treadmill; the green lights should always
be ON when power is supplied to the treadmill. Yellow indicates a treadmill function. Red indicates a
treadmill malfunction. Here is a list of each LED and what it signifies:
AC PWR (green) - The AC PWR (Alternating Current Power) illuminates when AC line voltage is
delivered to the treadmill. It then passes through the in-line fuse (110)/s(220) and lights the AC PWR
LED.
VDC (green) - The VDC LED will light when it receives DC voltage from the DC power supply.
DN & UP (yellow) - The DN and UP LED lights tell us if the elevation DN and UP relays are
functioning properly. When the LED lights, it tells us that the relay has energized and is sending high
voltage (110vac or 220vac) to the elevation motor.
UPSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper display
board to the elevation UP relay. This low voltage dc is what energizes the coil of the relay.
DNSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper display
board to the elevation DOWN relay. This low voltage dc is what energizes the coil of the relay.
BELTSW (green) - This LED will illuminate when the low voltage dc is delivered from the upper
display board to the belt (motor start) relay. This low voltage dc is what energizes the coil of the relay.
SPD (yellow) - The SPD LED flashes on and off (relative to speed) when the speed sensor is
operating properly.
PWM (yellow) - This LED will light when the upper board is sending a speed signal to the PWM.
Both the PWM LED and BELTSW LED must be lit for belt movement.
Finally this this Relay Board, the Each Led will be Lit, for any Relai control for DN down, or UP elevation motor. Use the contact cleaner, you can find it in R .Shack.
see the diagram attached.

The Steps for Newer Style Console Calibration:

  1. Locate the calibration area on the rear or underside of the console (a hole, near the console's center, that goes through to the electronics board. (This hole should not have a screw in it.)

  2. Insert a pencil (eraser end), into the hole and feel around for the cal button (will click when pressed).

  3. Press the button 2 times (with the pencil eraser). The first click should show CL11 in the console, the second click should show CL21.

  4. If the process was done correctly, and CL21 appears in the console, you are in "calibration mode." The next few steps consists of pressing buttons on the console and observing settings. This will not require any other tools.

  5. Press ENTER. CL22 should display in the TIME window and (??) in the SPEED window.

  6. Press ENTER. CL23 should display in the TIME window and (??) in the SPEED window.

  7. Press ENTER. CL24 should display in the TIME window and (??) in the SPEED window.

  8. Press ENTER. CL25 should display in the TIME window and (??) in the SPEED window.

  9. Press ENTER. CL26 should display in the TIME window. You should then see the letter "E."

  10. Press ENTER. You should see "SS" or "55" in the console.

  11. Push the STOP/START button. For safety, at this point, you should step off, or be off, the treadmill.

  12. Push the ENTER button. The walking belt should start to move, accelerate to maximum speed, then stop on its own.

  13. When the belt stops, the incline should self test by raising to its highest incline position, then lowering back down to its lowest position.

  14. Once the incline test is complete, push the POWER button 2 times. The unit should shut off and the console should go completely blank. If this happens, the treadmill is done calibrating and is ready for use.

  15. If the letter "F" appears in the SPEED or INCLINE window when the power button is pressed 2 times, the treadmill is indicating a failure somewhere either in the SPEED or INCLINE (depending on the window the "F" appeared in).

Motor tripping out power supply


The input to your treadmill is about 120 volts Ac. The output from the board will be about 30 Ac. Almost nothing on there will be measured in DC. Your particular issue is your motor controller. It needs to be replaced.

Principle of speed control on treadmill motors


Different manufacturers may employ different speed control techniques, related mostly to accuracy and cost. However, this link is probably representative of many PWM (pulse-width--modulated) controls. There are other ways to control speed and torque.
