Compensation

A compensation factor can be programmed for lift accelerators 1 and 2, lift switches 3 and 4, and
the power steer input (if configured).
The compensation factor is designed to help keep a constant lift speed or power steer assist level
under varying load conditions.
The compensation feature works by calculating how much extra motor voltage is needed to keep
the motor speed constant. The calculation uses the motor current and the relevant personality to
determine the extra motor voltage required.
To set the compensation factors for the lift accelerators or switches you should first set the desired
unloaded speed using the maximum speed personality for the lift input in question. The next step
should be to activate the lift under full load and increment the compensation personality until the
desired full load speed is achieved.
The following personalities may be programmed to provide compensation for the relevant inputs:
