Calibrating Adaptive Load Compensation; Tool) - Invacare LiNX Service Manual

Invacare® LiNX
be calculated manually, from observation, or automatically
with Adaptive Load Compensation (ALC).
Invacare recommends adding the motor resistance
values automatically, using Adaptive Load
Compensation. Adaptive Load Compensation is a
process that learns the resistance value of each
motor automatically, individually and with mΩ
accuracy. Because a separate and accurate resistance
value is applied to each motor, the wheelchair's drive
performance is significantly improved.
Adaptive Load Compensation is enabled by default,
so the Motor Resistance parameter value is not used.
For more information about ALC Calibration application
with iOS tool, refer to 5.3.1 Calibrating Adaptive Load
Compensation (iOS tool), page 46.
For more information about ALC Calibration application
with PC tool, refer to 5.3.2 Calibrating Adaptive Load
Compensation (PC tool), page 46.
After learning the motor resistance values with ALS
Calibration application, drive the wheelchair and observe its
performance over various surfaces and at different speeds.
Open Chair Setup –> Modules –> Power Module.
If the wheelchair does not perform as desired, the effect of
the adaptive load compensation can be adjusted using the
Load Compensation Percentage parameter:
• reduce value of this parameter if wheelchair drives
more aggressively than anticipated.
46
• increase value of this parameter if wheelchair drives
more sluggish than anticipated.
Load Compensation Percentage is only applied when
Adaptive Load Comp Enabled is set to on.
5.3.1 Calibrating Adaptive Load Compensation (iOS tool)
If the electronics or the motors have been
changed, you need to calibrate the Adaptive Load
Compensation (ALC).
1. From Home screen click on Chair Setup.
2. Click on Power Module.
3. Scroll down to Power Module – Load Compensation
section.
4.
Click on Go To ALC Calibration.
5.
Tap on Start Tuning.
6. Follow instructions on the screen.
5.3.2 Calibrating Adaptive Load Compensation (PC tool)
If the electronics or the motors have been
changed, you need to calibrate the Adaptive Load
Compensation (ALC).
