8.2.2
Running the motor in jog mode (JOG function)
The "Jog" function is typically used to slowly move a machine part, e.g. a conveyor belt.
With the "Jog" function, you switch the motor on and off using a digital input. When the motor
is switched on, it accelerates to the jogging setpoint. There are two different setpoints
available, e.g. for motor counter-clockwise rotation and clockwise rotation.
The same ramp-function generator acts on the setpoint as for the ON/OFF1 command.
