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.
Figure 8-8 Behavior of the motor when "jogging"
The inverter must be ready to start
before you issue the "Jog"
control command. If the motor is already switched on, then the
"Jog" command has no effect.
8.2.8
Switching over the inverter control (command data set)
In several applications, the inverter must be able to be operated from different, higher-level
control systems.
Example: You control the motor either from a central control system, via fieldbus or from a
local control panel.
