Figure 6-18 Behavior of the motor when "jogging"
After switching on, the motor accelerates to the setpoint, jog 1 or setpoint, jog 2. The two
different setpoints can, for example, be assigned to motor clockwise and counter-clockwise
rotation.
When jogging, the same ramp-function generator is active as for the ON/OFF1 command.
