Motor Outputs tab
These settings affect the operation of the motor outputs in all modes.
Current Limit
This setting sets the maximum current for the motor output. If the system tries to draw more current
than the setting, the output duty cycle will be reduced. For Sabertooth 2x32, each motor output can be
limited individually in a range between 0A and 64A. This is a soft current limit, and will slow acceleration
but allow motor motion to continue. There is also a fixed hard current limit above approximately 70
amps which protects the Sabertooth from a shorted motor.
Current Limit Smoothing
This setting changes how quickly the current limit responds. More smoothing will cause the Sabertooth
to ignore small overcurrent spikes for smoother operation.
Dead time
This is the length of time that the motor will stay in a regenerative braking mode after a stop command
is sent. After this delay, if the motor is still being commanded to stop, the motor output will shut down
to conserve power. Any command that would move the motors will immediately wake the Sabertooth
from this shutdown state.
Deadband
This is the range of input signals that the Sabertooth considers to be a zero speed input. If the setting is
left at Default the setting varies depending on the operating mode. For example, in Analog mode the
default deadband is from 2.375 to 2.625 volts. If the setting is changed to Custom, text boxes will
appear. Enter your desired deadband in these fields and this deadband setting will be used in all modes.
