C. SVMC series wiring diagram

1. Svmc series wiring diagram

2. Gerneral Wring For MQCON Controller and CA

Remark: all black wire is the same point with battery negtive and all ground is the same with battery negtive.

D. SVMC controller software interface

E. SVMC series wiring diagram

1. Orange ignition. : the wire should be connectted to battery positive.

2.1. H-brake: If the purple wire connect to 12V,the controller enter brake status, when it disconnect with 12V,the controller quit the brake status.

2.2. L- brake: If the Yellow wire connect to 0V(Battery negtive),the motor stop running.

High brake wire connect with 12v brake wire of hand brake/foot brake; low brake wire connect with ground wire.

High brake and low brake cannot using in the same time.

3. Reverse:If the white wire connect to 0V(Battery negtive),the controller enter reverse status,twist the throttle, the motor will spin in back direction. When the white wire disconnect with 0V,the controller quit the reverse status.

4. 3 speed function

3- speed mode(Botton):

When select the 3 speed(button )in the software. use a button(which can be reset by itself) to connect the pink wire and ground wire. 
Push it and release ,the speed gear will change according as follows: 3-2-1-2-3-2-1-2-3-…… 
When power on ,the controller is in 3 gear mode (high speed mode).
3 speed (switch):

When select the 3 speed (switch) in the software.
Use such switch to realize the 3 speed(switch) mode.

If 3 speed (switch) mode selected, 
a. Connect the pink and ground wire.
b. Enter high speed mode
c. Connect the transparent and ground wire. Enter low speed mode
d. Disconnect pink ,transparent wire and ground ,enter middle speed mode

5. 0-5v e-brake throttle:

Use a seperate throttle to connect to the teminal above.
Please select the “ Ebrake-throttle ” mode, When spin the throttle ,the controller will enter the e-brake mode , the brake strength will follow the the throttle positon. the max streng can be set from ” Electric brake phase current ” as following.

6. Motor termperature function.

The controller support kty83-121 termperature sensor from motor inside. The function can be enabled or 
disabled from the software.

7. MQCON controller can be connected with computer by usb cable or conneted with phone by bluetooth, the computer interface is just same with the phone app interface.

Connect with computer

Before connected with computer ,please install usbdrive and volume software provided by the controller manufacturer


The usb cable should be connected in right way as the following picture showed:

For information about “ how to use computer to set the parameters ” , Please ask seller for document ” MQCON controller application user manual” and “ MQCON(Sabvoton) FOC Controller "
Parameter Manual-EN ” 
The controller can communicate with the phone app.

For information about “ how to use phone bluethooth to set the parameters ” , please ask seller for User manual.
8.  Hall angle ---the most important parameter for MQCON controller. 
Different type motor should use different angle in controller.
If use improper angle , the motor may not run in best status.
When the user does not know the “hall angle ”in advance , the user should get the paramenter by using automatic testing function in the software . if the user know the parameter in advance ,just enter the right angle. For svmc series controller ,if used QS V1 or V2 type motor ,the hall angle is about 65. If use QS V3 type , the angle is about 250.

F. Additional notes:

1. All RTN pins are internally connected.

2. Meter function is to copy either of hall sensors.

3. Above pin definition is for classical type controller.

Pls. Contact with sales first if you don't know how to connect the controller with motor and other parts.

3. CT-22 programable LCD speedometer

4. Throttle with 3 speed slide switch

5. DC-DC converter 

Please noted:

Optional appearance, drawing, performance curve/test report are available.
