Fine-tuning
Depending on the application further fine tuning may be required to maximize performance on an incline.
The following parameters have the default values indicated below. – These are theoretically optimal values given a correct value
of motor compensation determined for the lowest armature temperature that is likely to be encountered in normal operation.
- Enhanced Motor Compensation (Down) = 150%
- Enhanced Motor Compensation (Up) = 130%
- Enhanced Motor Compensation (Up) Gain = 1%
This parameter is used to fine tune the vehicle performance when stopping on a hill after driving in the Up direction. It is
programmable between 100% and 200% in steps of 1%.
If the vehicle rolls backwards after the tiller is released and before the solenoid brake is engaged, increase the value of
Enhanced Compensation (Up) in steps of 5%.
If the vehicle rolls forwards after the tiller is released and before the brake comes on decrease the value Enhanced
Compensation (Up) in steps of 5%.
If a perfect performance cannot be achieved, i.e. roll-back cannot be eliminated, then choose the best value of Enhanced
Motor Compensation (Up) and move on to adjusting the next parameter, Enhanced Motor Compensation (Down).
Enhanced Motor Compensation (Down)
This parameter is used to fine tune the vehicle performance when stopping on a hill after driving in the Down direction. This
parameter is adjustable between 100% and 200% in steps of 1%.
Drive the vehicle down the incline at full speed and release the tiller.
The vehicle should come to a complete stop just before the solenoid brake is engaged.
If the vehicle is still moving when the solenoid brake engages, increase the value of Enhanced Motor Compensation (Down) in
steps of 5%.
If the vehicle recoils (momentarily drives in reverse) before the solenoid brake engages, decrease the value of Enhanced
Compensation (Down) in steps of 5%.
Enhanced Motor Compensation (Up) Gain
This parameter is used to fine tune the vehicle performance when stopping on a hill after driving in the Up direction. If, at this
stage, the performance is satisfactory, then do not adjust this parameter.
Enhanced Motor Compensation (Up) Gain is programmable from 0 to 100 in steps of 1%.
Drive the vehicle at full speed up the incline and release the tiller.
If the vehicle rolls backwards after the tiller is released and before the brake engages, increase the value of Enhanced Motor
Compensation (Up) Gain until the roll-back after stopping on the incline is satisfactory.
Be aware that the resistance of the motor will alter with the temperature of the motor.
Parameter values determined with a hot motor may need to be verified and possibly
retuned when the motor has cooled down.
