| Please notice that the response curves for the NON-MIXED
operation MUST be programmed. Leaving the relevant jumpers off in the
NON-MIXED mode results in indeterminate response curves. The
"NON-MIXED" portion of the chart refers to "select curve
from above". Use the "STEERING
INPUT CURVES" in "MIXED MODES-Separate Curves" for
Motor #1 input S, and the "THROTTLE INPUT
CURVES" for Motor #2 input T. The curve(s) labeled
14 are a good choice. For robot speed control applications do NOT select a "NONE" Deadband curve like curve 4.
Add J2 to get the NON-MIXED operation and set JP7,8,9 to suit
acceleration and braking. Longer acceleration times are easier on mechanical
components and starting currents imposed upon the battery. For competitive
robots do NOT attempt to change the PWM rate, leave JP18 in place for 338 Hz.
