multiple
modes
The AX2550 may be connected to two motors which will react to commands received on two input channels. Using these
two channel inputs, the motors can be commanded independently or in a combined fashion to accommodate the most com-
mon drive and steering methods in robotic vehicles.
command
Independent Speed Commands
In this mode, each of the two motors is
commanded independently of the other.
This operating mode is best suited for
generic motor control applications.
Mixed Speed/Steering Commands
In this mode, the motors work in combina-
tion to move and turn a vehicle by combin-
ing the forward/reverse command informa-
tion and the left/right steering information.
This mode of operation provides a cost
effective method for moving and steering
tank-style robots and underwater vehicles.
Speed and Position commands
In this mode, one channel is used to con-
trol the forward/reverse motion of the vehi-
cle. The other channel is used to make the
motor work like a position servo which can
be then connected to a steering column.
This mode is the most energy efficient as
no power is lost to friction due to skidding.
Ch1 controls Motor 1’s speed
Ch2 controls Motor 2’s speed
Ch1 and Ch2 are mixed to control
Motors 1 & 2 in coordination
Ch1 controls Motor 1’s speed
Ch2 controls Motor 2’s position
Ch1 controls Motor 1’s position
Ch2 controls Motor 2’s position
Dual Position Commands
In this mode, each channel independently
controls the angular position of one motor.
The heavy duty servos built in this way can
be used to control throttle, brakes, and
steering of life-size vehicles or animate any
large and heavy structure.
