Sabertooth 2x10 RC User`s Guide

1. your robot gets flipped upside down It can connect to either a OV 5V signal for automatic flip correction or an R C channel usually channel 5 or 6 for radio controlled flip correction Mounting Sabertooth 2x10 RC mounts with four 4 40 machine screws included on a 1 5 x 2 hole pattern For best thermal performance it should be mounted with the bottom aluminum heat spreader connected directly to a metal chassis if possible Indicator LEDs The red Error LED will light to indicate overheating or current limit The green Status LED will glow dimly when power is applied and brightly when a radio signal is present The green Status2 LED will flash out the detected number of lithium cells when lithium mode is enabled Options All options are set by using the option switches Mixing mode With switch 1 in the UP position the controller is in mixed mode Switch 1 in the DOWN position as shown turns mixing mode off Note that Flip Switch 4 only affects Motor 2 if mixing mode is off Exponential If switch 2 is in the UP position the controller will be in exponential mode This makes the response less sensitive in the center This is useful to bring very fast robots under control If Switch 2 is in the DOWN position as shown exponential is disabled and the response is linear Lithium Mode Switch 3 in the DOWN position as shown enables Lithium mode for use with Lithium batteries This will shut the controller down at 3 0 volts per ce2. Sabertooth 2x10 RC User s Guide Input Voltage 6V to 25V 2s to 6s lithium Output current Up to 10A per motor Peak output current Up to 15A per motor Weight 1 10z 32 grams Size 2 3 x 1 8 x 75 DimensionEngineering Sabertooth 2x10 RC is designed for combat robots from 160z to 121b and general purpose robots up to 100Ib It controls two motors in mixed or independent modes Its synchronous regenerative drive allows for high efficiency operation and recharges your battery when you slow down or reverse It is internally protected from damage due to overheating and over current Installation Overview Battery connections The positive usually red wire connects to the B terminal and the negative usually black wire connects to the B terminal Using a polarized mating battery connector such as Deans Ultra is recommended to ensure a reliable connection Motor connections Connect Motor 1 to the M1A and M1B terminals and Motor 2 to the M2A and M2B terminals Fwd CH1 connector This connector controls the forward backwards motion of your robot in Mixed mode and Motor 1 in independent mode It is usually connected to the elevator channel on an R C receiver Turn CH2 connector This connector controls the turning motion of your robot in Mixed mode and Motor 2 in independent mode It is usually connected to the aileron channel on an R C receiver Flip connector This connector is used to reverse the steering if
3. ll preventing damage to a Lithium battery pack The detected cell count is flashed on the Status 2 LED Switch 3 should be in the UP position when using NiCd NiMH or lead acid batteries Flip control Switch 4 in the UP position sets flip to R C mode When R C mode is set the bot s steering will be reversed if the R C pulse is 1500us or longer Switch 4 in the DOWN position as shown sets flip to digital input mode If you are not using the Flip channel if your bot is not invertible set switch 4 to DOWN Auto Calibrate Switch 5 in the UP sets auto calibrate mode In auto calibrate mode the neutral position is read at power up and the endpoints are automatically detected This maximizes your useful stick travel and allows use with pistol grip transmitters with 70 30 throttles Switch 5 in the DOWN position always uses 1000us for full reverse 1500us for stop and 2000us for full forward Timeout Switch 6 in the UP position enables timeout If no signal is received for 1 second the controller turns the motors off This prevents your bot from driving away if you get interference If Switch 6 is in the DOWN position timeout is disabled and the controller will run at the last commanded speed until a new command is given This is useful when running from a microcontroller like a Basic Stamp
