• Once the Kp setting for marginal stability is found, reduce the Kp value by about one-
third (i.e., nal Kp = marginal stability Kp * 2/3).
• If using Speed Mode Express, enter this Kp value for the Kp parameter in the Speed
Mode Express menu.
• Set the Max Speed, Accel/Decel, Soft Stop Speed, Position Hold, and Brake Type
parameters back to their original values.
1.5 In the Speed Mode » Response menu, adjust the Accel and Decel Rate parameters as necessary
while moving the throttle to dierent positions (i.e., neutral to full throttle, half throttle to full
throttle, full throttle to half throttle, full throttle to neutral, neutral to low throttle, etc.).
1.6 In the Speed Mode » Response menu, adjust the remaining Brake Rate parameters as necessary
while reversing the throttle input (i.e., full throttle forward to low throttle reverse, full throttle
forward to full throttle reverse, full throttle reverse to low throttle forward, etc.). If a brake input
is present in the application (Brake Pedal Enable = On) continue adjusting these Brake Rates by
applying dierent amounts of brake throttle (i.e., full throttle forward, then apply full brake or
full throttle forward, then apply low brake, etc.).
1.7 e parameters in the Speed Mode » Response » Fine Tuning menu typically do not need to be
changed as the default values work well in most applications.
2 − Torque Mode Tuning
2.1 Set the Torque Mode’s Max Speed to the application’s maximum motor speed (rpm).
Programmer: Torque Mode » Max Speed (0x391D)
2.2 Set the Typical Max Speed to the expected maximum motor speed (rpm).
Programmer: Motor Setup » Typical Max Speed (0x3543)
2.3 e Torque Mode’s Kp, Ki, and Kd parameters typically do not need to be changed as the default
values will work well in most applications. ese parameters control how tightly the controller
limits the speed of the motor to the programmed Max Speed.
