Running servo in opposite direction

Hello,

I have an application for this servo motor:

DDTS380 400KG/CM Large Servo 24V Power Supply Precision Servo High Torque x-top.

I have two of these servos working together, I need one to change the direction of rotation. Can I do this by reversing the control wires? Please attached

Technical Parameters:

  • Rated voltage: DC 24V (12V-24V can work, 12V torque and speed are halved)
  • No-load current: <500MA (load current 5-10A, it is recommended to use 10A or more than 10A switching power supply or battery, the greater the power supply current output capacity, the better)
  • Limit angle: 1200-1700US: about 90 degrees; 500-2500US: about 288 degrees (Pulse width determines the angle. If you need other angles, please increase or decrease pulse width by yourself, the maximum is about 288 degrees)
  • Control mode: 1.0-2.0 MS pulse: suitable for model airplane remote control receiver control; 0.5-2.5 MS pulse: suitable for multi-channel steering gear controller control (pulse frequency: 50-333HZ)
  • Materials: * Gears and shafts: alloy steel, hardened steel, aluminum alloy; * Shell: aluminum alloy
  • Servo weight: about 880g
  • Speed: 0.5S/60° (equivalent to 20RPM)
  • Mechanical life: >300,000 times (370 hours)/(30KG/CM)
  • Torque limit: 400KG/CM (Broken gear load, it is not recommended to work at this torque)
  • Starting torque: 380KG/CM (short-time work)
  • Conventional torque: 140KG/CM (can work for a long time)

Thanks,
Jeffrey

Negative, Jeffrey,

The servo’s angular position is determined by the pulse width of the drive signal. Given these specifications:

1200-1700US: about 90 degrees; 500-2500US: about 288 degrees (Pulse width determines the angle. If you need other angles, please increase or decrease pulse width by yourself, the maximum is about 288 degrees)

The servo is approximately centered with a pulse width of 1500 microseconds. It has the ability to rotate +/- 144 degrees from center when the pulse width is 500 (minimum) to 2500 microseconds (maximum). For more information about RC servos may I recommend this Arduino page. Please look for the animation that shows servo position based on pulse width.

You mentioned “working together.” Does this imply the servos are mechanically connected together to drive a large load? If yes, this can cause problems as each RC servo typically has a slightly difference in angular position for a given pulse width. When mechanically placed in parallel they may work against each other like an unmatched team of horses. The resulting current may be high and the servo motors may overheat.

Best Wishes,
