Parameter
Description
In mot cmp
Sets the indoor motor compensation which is the calibration value
used to compensate speed control for varying terrain, also known as
Power On Demand (POD). Set to 0 for no speed control
compensation.
To calibrate:
Step
Action
1
Set In mot cmp to 0
2
Set In FWD spd to 50%
3
Drive at full throttle on flat terrain and measure vehicle
speed
4
Drive at full throttle on a moderate incline and increase
the In mot cmp until the vehicle’s speed matches the
speed measurement in step 3
5
Verify that PWM is not 100% (monitor PWM in the
Debug menu)
6
Is PWM is 100%?
 If yes, reduce FWD speed and continue with step 3
 If no, continue with the next step
7
Reduce the In mot cmp value by 20% to allow for
temperature tolerance of the motor and controller
Setting this parameter too high can result in an
over compensated drive motor that may behave
erratically. Please seek advice from your
manufacturer or dealer before attempting to
calibrate this parameter. This feature should
typically only be used by the manufacturer.
