Situation 2: “M2-1 Control Mode “Spd/Torq”” = 1 (Torque control mode) and “M1.5-1 Hill hold enable
”Off/HH/S””=0 (No Hill Hold)
In this case the controller acts to control the torque and no hill hold is selected, thus the parameters “M1.5-2 Hill hold
time ”HHTime””, “M1.5-3 Restraint hill hold speed ”HHspeed”” and “M1.5-4 Restraint hill hold torque threshold
”HHTrqTH”” won’t be active.
End of braking in Torque control Mode and no hill hold
The following list describes the “end of braking” steps:
1. the speed decreases according to “M1.1-3 Neutral brake torque “NBrake”” (if neutral braking is happening) or
to “M1.1-9 Foot brake torque “FBrake”” and the “Brake pot %” value (refer to “M1.7-1 Brake pot minimum
voltage level “BrkMin”” and M1.7-2 Brake pot maximum voltage level “BrkMax””) (if foot brake is operated);
2. when speed is below setting “M1.2-1 Speed threshold to enter End-of-Braking (EoB) mode ”SpdThEoB””, the
controller reduces brake torque in a smooth way (proportionally to speed) to assure a smooth stop operation;
3. when speed is below “M1.2-2 Zero speed threshold ”ZSpdTh””, the vehicle is let coast with the controller giving
power to the motor until “M1.2-3 Neutral brake-end delay “NBrkEnd”” time is elapsed;
4. the controller stops giving power to the motor and the vehicle is let coast or roll on slope (if any) unless
mechanical brake or electromechanical brake is applied.
During the end of braking operation, If pedal brake is removed and a direction selected with accelerator pedal demand
(add foot switch in case of ride vehicle) the vehicle will start to move in the selected direction.
