SPEED MODE — SPEED CONTROLLER MENU
PARAMETER ALLOWABLE RANGE DEFAULT DESCRIPTION
Max Speed
Max_Speed_SpdM
0x383A 0x00
100 – 24000 rpm
100 – 24000
4000 rpm Denes the maximum requested motor rpm at full throttle. Partially
applied throttle is scaled proportionately; e.g. 40% applied throttle
corresponds to a request for 40% of the set Max Speed Value.
Note:
• The maximum motor rpm is subject to the lower of the three
rpm constraints.
Kp
Kp_SpdM
0x3831 0x00
0.0 – 200.0
0 – 16384
30 % The proportional term (Kp) determines how aggressively the speed
controller attempts to limit the speed of the motor to Max Speed.
Larger values provide tighter control.
If Kp is set too high the system may experience oscillations as the
controller tries to control speed.
Setting Kp too low may result in an overshoot beyond Max Speed.
Ki LS
Ki_SpdM
0x382F 0x00
5 – 100 %
50 – 1000
30 % The Ki LS parameter sets the Ki for low vehicle speeds. The integral
term (Ki) forces zero steady state error so the motor will run at
exactly the commanded speed. Larger values provide tighter control.
High gain values may cause the system to experience oscillations
as the controller tries to control speed.
If the gain is set too low, the motor may take a long time to
approach the exact commanded speed.
Ki HS
Ki_HS_SpdM
0x382C 0x00
5 – 100 %
50 – 1000
30 % The Ki HS parameter sets the Ki for high vehicle speeds. The integral
term (Ki) forces zero steady state error so the motor will run at
exactly the commanded speed. Larger values provide tighter control.
If the gain is set too high, oscillations may occur as the controller
tries to control speed.
If the gain is set too low, the motor may take a long time to
approach the exact commanded speed.
Speed Mode Parameter menus
Speed Mode oers the highest number of motor response parameters. Note, pertaining to the optional
Speed Mode Express parameters within the Speed Mode menus as noted above, always use the VCL
parameter name as shown in the selected Curtis Integrated Toolkit
TM
control mode selection. Within
the parameter menus are read-only monitor variables (~ italicized below), which are helpful when
setting parameters and their eects.
