Compensation Menu
Use the Compensation parameters to congure the motor resistance that the controller applies to
compensate for the following conditions:
• Increased load caused by uneven terrain.
• e operator releases the throttle to neutral at near-zero speeds while the vehicle is on a slope.
e following table describes the parameters on the Compensation menu.
Note: For steps on conguring these parameters, see Adjust IR Compensation on page 68.
MOTOR SETUP MENU — COMPENSATION MENU
PARAMETER VALUES DEFAULT DESCRIPTION
IR Comp 0-100% 70% Sets the resistance that the controller applies to compensate for
increased load caused by uneven terrain.
The value is a percentage of the System Resistance parameter.
See page 52.
Higher values increase the vehicle’s ability to overcome load
disturbances, while lower values provide smoother operation.
Anti-Rollback Comp 0-125% 90% Sets the resistance that the controller applies to prevent rollback
when the operator releases the throttle to neutral while the speed
is near zero.
The value is a percentage of the System Resistance parameter.
Higher values provide more hill-holding force.
Speed Sensor Menu
e following table describes the parameters on the Speed Sensor menu. For more information on
using a speed sensor, see page 25.
MOTOR SETUP MENU — SPEED SENSOR MENU
PARAMETER VALUES DEFAULT DESCRIPTION
Speed Sensor Enable [PCF] On/Off Off Species whether the speed sensor function is on.
When Speed Sensor Enable is on, Analog 6 is used as the
sensor’s input and Switch 6’s state is always off.
Limit Max Speed On/Off On Species whether the controller uses the speed sensor to limit
the vehicle’s maximum speed.
The Max Speed parameter denes the maximum speed.
Encoder Fault Threshold 5-50% 25% Sets the threshold above which the controller will report an
Encoder Fault.
The controller reports this fault when the motor’s duty cycle is
higher than the threshold and the controller does not receive any
pulses from the speed sensor.
Pulses/Rev 1-32 16 Sets the speed sensor’s pulses per revolution. The controller uses
this value to calculate the vehicle speed.
Max Speed 100-6000 RPM 3000 RPM Sets the maximum speed of the motor, in RPM, to which the
controller limits the vehicle when Limit Max Speed is on.
Note: To monitor the vehicle speed, use the Motor RPM eld; see
page 59.
