Throttle %: This displays the throttle position as percent of
maximum position.
Throttle Voltage: This displays the wiper voltage from the throttle
potentiometer.
Current: This displays the net amperage to the drive motor.
RPM: This displays the output rpm of the wheel motor.
Phase A and B rpm: These are the effective rpm’s of the A and
B phase encoders within the wheel motor. They represent the
frequency of the PWM signal.
Interlock (Seat Switch): This represents the status of the seat
switch. A value of “1” indicates the switch is closed and the operator
is seated.
E-Stop: This represents the E-stop switch. A value of “1” indicates

of the wheel motor. The motor has an internal temperature sensor
and reports this value to the Drive Controller.
M11 Temp Cutback %: This represents the percentage of power
available to the motor when reduced due to an over-temperature
condition within the motor, to protect the motor.
