+ Speed/ - Speed Around a Reference:

• When the run command is given, the motor will reach the speed reference f ollo wing the a cceler ation

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 t he speed ref erence and the speed ad justed b y

+ 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.
