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 center points are calibrated at start up 
unless disabled by enabling MCU mode which sets the center at 1v. The RoboClaw will auto 
calibrate these ranges on the y unless auto-calibration is disabled. If a voltage smaller than .5v 
or larger than 1.5v is detected the new voltage will be set as the minimum/maximum.
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 dierentially 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.
