Analog Control
Analog Mode
Analog mode is used when controlling RoboClaw from a potentiometer or a ltered PWM signal.
In this mode S1 and S2 are set as analog inputs. The voltage range is 0V = Full reverse, 1V =
Stop and 2V = Full forward.
Analog Mode With Mixing
This mode is the same as Analog mode with the exception of how S1 and S2 control the attached
motors. When used with a differentially steered robot, mixing mode allows S1 to control the
speed forward and backward and S2 to control steering left and right.
Analog Mode with feedback for velocity or position control
Analog Mode can be used with encoders. Velocity and/or Position PID constants must be
calibrated for proper operation. Once calibrated values have been set and saved into Roboclaws
eeprom, encoder support using velocity or position PID control can be enabled. Use Ion Studio
control software or PacketSerial commands to enable encoders for RC/Analog modes (see
Conguration Using Ion Studio).
Analog Mode Options
Option Function Description
1 TTL Flip Switch Flip switch triggered by low signal.
2 TTL Flip and Exponential Enabled Softens the center control position. This mode is ideal
with tank style robots. Making it easier to control from
an RC radio. Flip switch triggered by low signal.
3 TTL FLip and MCU Enabled Continues to execute last pulse received until new
pulse received. Disables Signal loss fail safe and auto
calibration. Flip switch triggered by low signal.
4 TTL FLip and Exponential and MCU
Enabled
Enables both options. Flip switch triggered by low
signal.
5 RC Flip Switch Enabled Same as mode 1 with ip switch triggered by RC signal.
6 RC Flip and Exponential Enabled Same as mode 2 with ip switch triggered by RC signal.
7 RC Flip and MCU Enabled Same as mode 3 with ip switch triggered by RC signal.
8 RC Flip and Exponential and MCU Enabled Same as mode 4 with ip switch triggered by RC signal.
