6 — TUNING GUIDE
c. Kp and Ki typically do not need to be changed as the default values will
work well in most applications. If you want to adjust Kp (for looser or tighter
following of the speed trajectory set by the accel, decel, and brake rates),
follow the procedure in step “c” in the Speed Mode tuning section.
d. Adjust the Accel Rate and Decel Rate as necessary while moving the throttle
to different 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.).
e. Adjust the Brake Rate 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.).
1 - SPEED MODE tuning (see pages 27–30)
a. Adjust Max Speed to the maximum speed the motor should turn in the vehicle
application; this speed setting corresponds to an input of full throttle.
b. Adjust the Typical Max Speed (page 48) to the approximate maximum speed
that the motor will spin. This is usually the same value as the setting for Max
Speed, but some applications have a Max_Speed_SpdM that changes (in
the VCL software). If the Max_Speed_SpdM changes, set the Typical Max
Speed to the highest speed the motor is expected to reach. This value does
not need to be set precisely since it will not change motor performance. Typi
-
cal Max Speed sets a reference point for the “rate” parameters (accel, decel,
brake rates), so that applications that have a changing Max_Speed_SpdM
will not experience changes in the rates (because the rates are referenced to
the unchanging Typical Max Speed value). Once you set the Typical Max
Speed parameter you should not readjust it without adjusting all the rate
parameters as well.
c. Kp typically does not need to be changed as the default value will work
well in most applications. This parameter controls how tightly the ac
-
tual motor speed will track the requested speed trajectory (speed trajec
-
tory is set by the accel, decel, and brake rates).
If you want to adjust the Kp (for looser or tighter following of the speed
trajectory), follow these guidelines.
• Set the following parameters. Before setting them, make a note
of their present (default) settings so you can return them to
these original values at the end of this procedure.
*
If your vehicle has an EM Brake, set the Brake Type (page
42) to 1. This setting will release the EM Brake as soon as
interlock is asserted.
*
In the Speed Mode
» Response menu, set all the accel and
decel rates to their fastest values (0.1 seconds); this allows
better observation of the system response.
