Jogging
The "Jog" function is typically used to temporarily move a machine part using local control
commands, e.g. a transport conveyor belt.
Figure 6-18
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.
