RANGE
On/Off
Enables/disables the patented Auto-Trim feature; see page 4.
Sets the motor trim, allowing for straight line tracking despite differences
in motor characteristics. Setting this parameter to zero provides no steering
correction.
On/Off
Enables the controller's algorithm for determining whether a drive motor
is not connected.
On/Off
Enables the controller to use open motor test data to determine the
resistance of the attached motor.
5–50 %
Sets the amount of current applied during open motor detection and motor
R measurement, as a factor of controller current limit.
If open motor detection is required but not automatic motor resistance
measurement, this should be set to the minimum value. If motor R
measurement is required, this must be set high enough for the motor
resistance measurement to have adequate resolution to get an accurate
measurement, typically 30–50%.
0–477
Sets the actual system resistance (motor + brushes + wiring + connections)
used for load compensation and speed estimation for motor 1.
It is important that the value set here is taken directly from the Motor
Test described below.
0–477
Sets the actual system resistance (motor + brushes + wiring + connections)
used for load compensation and speed estimation for motor 2.
It is important that the value set here is taken directly from the Motor
Test described below.
0–90 A
Sets the level to which the motor current will cut back if the motor's
thermal protection threshold is exceeded.
Sets the estimated time that the motor can withstand maximum drive
current before overheating.
When the motor overheats, the drive current is cut back until it reaches
the programmed Motor Current Rating. The Motor Cutback Gain
determines how quickly this cutback will occur, once the Time at Max
Current has expired.
Gear softening allows smoother transitions between forward and reverse
and is more noticeable when the chair is tuned aggressively (i.e., with
extremely fast accel/decel rates and max speeds).
A gear softening value of 100% provides maximum softening, and a
value of 0% eliminates the feature.
On/Off
Allows using only the M1 brake output to drive two 12V brakes in series.
