Temperature Rollback Maximum
To protect the Power Module from overheating, a thermal roll-back algorithm
reduces the output current when the Power Module becomes too hot.
Temperature Rollback Minimum is the temperature at which the thermal
roll-back starts.
Temperature Rollback Maximum is the temperature at which the thermal
roll-back limits the output current to zero.

4.3.4.8 Halve Turning Gain
Parameter Possible Values Default Rev HHP Lite Std Adv
Halve Turning Gain No / Yes No A -
Halve Turning Gain halves the values of the
Turning Speed @ Maximum (5.3.7.9) and
the
Turning Acceleration (5.3.7.11) parameters for every Drive Profile (for more
information on
Drive Profiles see 5.3.2).
This allows lower turning speeds and acceleration without a loss of resolution.
Enabling Halve Turning Gain is particularly useful for high speed chairs and Front
Wheel Drive chairs where low turning speeds are required.

Non-Linear Turn (section 5.3.7.13).
Note:
Wizard 5 uses the value of the Halve Turning Gain parameter to
determine the Power Module Revision (Rev –, or Rev A). Set this
parameter to Yes if you want to use the Rev A parameters. If the
Halve Turning Gain parameter is set to No, the Wizard will assume that
the program is meant for a "Rev–" Power Module, and will return all
Rev A parameters to their default values before it writes the
parameters to the Power Module.
