CONTROL MODE SELECT
PARAMETER ALLOWABLE RANGE DESCRIPTION
Control Mode Select 0 – 2 This parameter determines which control method will be in effect when
programming motor response:
0 = SPEED MODE EXPRESS
1 = SPEED MODE
2 = TORQUE MODE
Contact the Curtis distributor or support engineer if there is interest in a
non-generic control method. Note: Such a case will almost always require
time, which may delay any immediate project’s time-frame over the
standard options.
NOTE: Do not change this parameter while the controller is powering the
motor. Any time this parameter is changed a Parameter Change Fault (fault
code 49) is set and must be cleared by cycling power; this protects the
controller and the operator.

PARAMETER ALLOWABLE RANGE DESCRIPTION
Max Speed 100 – 10000 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.
If Max_Speed_SpdMx is set <10 rpm (through VCL or CAN), the throttle
request is zeroed.
NOTE: The maximum motor rpm is subject to the constraints on page 26.
Max_Speed_SpdMx 100 – 10000
0x3840 0x00
Kp 0 – 100% Determines how aggressively the speed controller attempts to match
the speed of the motor to the commanded speed. Larger values provide
tighter control.
If the gain is set too high, the application may experience oscillations as the
controller tries to control speed. If it is set too low, the motor may behave
sluggishly and be difcult to control.
Kp_SpdMx 0 – 8192
0x3841 0x00
Ki 5 – 100% 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, the application may experience oscillations as the
controller tries to control speed. If it is set too low, the motor may take a long
time to approach the exact commanded speed.
Ki_SpdMx 50 – 1000
0x3842 0x00
Accel Rate 0.1 – 30.0 s Sets the rate (in seconds) at which the speed command increases when
throttle is applied. Larger values represent slower response.
Accel_Rate_SpdMx 100 – 30000
0x3843 0x00
Decel Rate 0.1 – 30.0 s Sets the rate (in seconds) that is used to slow down the vehicle when the
throttle is reduced. Larger values represent slower response.
Decel_Rate_SpdMx 100 – 30000
0x3847 0x00
Brake Rate 0.1 – 30.0 s Sets the rate (in seconds) at which the vehicle slows down when brake is
applied or when throttle is applied in the opposite direction. Larger values
represent slower response.
Brake_Rate_SpdMx 100 – 30000
0x3848 0x00
