+ Speed/ - Speed Around a Reference:
•When the run command is given, the motor will reach the speed reference following the acceleration ramp.
•A pulse on + speed or - speed will change the motor speed. The motor will change speed following AC2 or DE2.
•If the Speed reference is changed, the ratio between the speed reference and the speed adjusted by + speed or - speed will be constant. This ratio is limited by the parameter (SRP).
•Adjustments around the setpoint using + speed and - speed are made following the AC2 and dE2 ramps.
