Notes:
The time that the R
HINO
2 will deliver the maximum sustained current to the
motors is limited by the Stall Timeout parameter (4.4.5.11).
To protect the electronics of the R
HINO
2, the maximum current will be reduced
further if the controller becomes too hot.

 
The
R
HINO
2 can deliver an additional current ( Boost Current ) of 10A (DS90), and 20A (DS120,
DS160) for the Boost Time of up to 10 seconds, to overcome transient loads such as starting
on a hill, climbing obstacles, etc.
If the Boost Time is reached, then the current is limited to Current Limit.
Before the current can reach the Boost Current value again, the motor current must stay
below the value of Current Limit for at least twice as long as it was above Current Limit.
4.4.5.11 Stall Timeout
Parameter Possible Values Default HHP Lite Std Adv
Stall Timeout 0 – 51s 15s   
If the throttle is deflected but the scooter can not drive because
It is on a slope that is too steep, or
It tries to climb up a curb that is too high, or
It is trapped,
then the maximum current (as set by the Current Limit parameter) will flow through the motor
continuously, because the motor is still trying to drive. This situation is called motor stalling.
Motor stalling can cause motor damage when the motor becomes too hot. To prevent
motor damage, the
R
HINO
2 disables drive after Stall Timeout seconds of maximum continuous
current.
If a stall timeout occurs, the scooter performs an emergency stop and the Status LED shows
Flash Code 4 (see section 5.2 for flash code descriptions). The scooter does not drive. To reset
the fault, turn the scooter off and turn it back on again.
