I’m building a lawnmower using 2 Jazzy Electric Wheelchair motors, 2ea Lead Acid batteries 12VDC connected in parallel for a 24VDC source controlled with a Flysky-FS-CT6B-2-4Ghz-6CH-RC-Transmitter. Receiver is connected to motor driver as: CH1 (Left & Right) to S1 and CH2 (Forward & Reverse) to S2. DIP sticks are as: 1=Off, 2=On, 3=Off, 4=On, 5=On, 6=On. When using the R/C, both M1 & M2 outputs modulating progresivly up to a 100% power (verified with DEScribe PC software , but (here is the problem), M2 start to move a bit, then doesn’t move at all. M1 is works as should be. Without moving the joystick M1A&B shows 7.9Vdc and M2A&B no voltage present. Any suggestions???
To verify if the issue is caused by the motor, please could you try swapping both motors and see if the behavior is the same?
What are the specifications of the motors?
Also, make sure your remote is calibrated when powered up.
Make sure the center position of the joystick is the zero.
Have you tried the Independent mode with DIP switch 4 to OFF?
I forgot to mention on my original message that I already tried 3 things; 1) I swapped motor’s cables from M1 & M2 respectively obtained same output described, this make me to something is wrong with M2’s output. 2) Also, I tested both motors connecting them directly to battery and both are working fine. 3) Tried DIP config: 1=Off, 2=On, 3=On, 4=On, 5=On, 6=On as suggested for R/C mode on Start Guide.
Related motor’s specs: I’m using PRIDE Motors P/N DRVASMB7120034 & 35 (Left & Right). 350 watts continuous / 1250 watts peak ratings. 4 pole brushed dc motors. Rpms are ROUGHLY 120rpm at 24vdc / 60rpm at 12vdc. Insul Class: F.
About transmitter is a self calibrate so I always make sure to turn “ON” transmitter before power up the motor driver and joystick is at zero position as well the trims.
Regarding moving DIP switch #4 to OFF position, Should I make any changes on motors cables connections related to M1 & M2 outputs?
Please, make sure your power source is 24V.
Also, note that 1250 watts peak power at 24V means it can draw 52A. This is way over the specifications of the Sabertooth 2X32.
Have you tried the driver with smaller motors to make sure it works fine?
Please, provide a picture of your wiring, it would help to figure out if DIP #4 would change something.
I tried to turning switch #4 OFF; It moves the motors OK but just once per channel. Meaning, when moved the joystick FWD & REV [channel 1], just moves Motor #2 (responding correctly to joystick movement) & nothing on motor #1. Then when moved joystick left & right [channel 2] just moves Motor #1 (responding correctly to joystick movement) & nothing on motor #2. (Hopefully I explained myself…)
